Looking through the Index moves | Analyzing Weightage based Segments

One of the perennial questions that’s in my mind as an Index trader is “What caused that move?” - We at NiftyScalper have been down several rabbit holes to find the answer, hopefully there is some light at the end of this “Market Internals” tunnel.

One of the things we are experimenting at the moment is looking at the index in segments.

Below are the three segments that you can see.

Segment 1 - HeavyWeights - In Red - 60% Weightage

Segment 2 - Mids - In Yellow - 22 % Weightage

Segment 3 - Bottoms - In Blue - 18% Weightage

Creating these segments helps us see the Index in a different light. One of the initial beliefs which we had about constituent stocks is that the bottoms which constitute 18% of weightage may not have much predictive value for the index, but we are learning something new about that belief, which I would share further down in this post.

Lets go back to the initial question that we started with “What caused this move?” - When I ask that question do note that I am usually looking at those Short time frame swings or trends which last anywhere between 45 mins to an hour.

To answer that question we look at the Average % Change of Prices of Constituents stocks in the above three segments of the Index. Do note, the Red line is the HeavyWeights, Yellow the Mids and Blue the Bottoms.

Image 1

To make it distinct visually I have drawn these boxes. Look at the first box in Image 1. That upward spike and the up move thereafter, it was the heavyweights which caused it, also notice the other two segments in the same time window, they are clearly diverging.

If you ask “Who caused that Up move?” - The answer clearly is the “HeavyWeights”. And if you ask who caused that down move - The answer clearly is the - “Mids” and the “Bottoms”. You will notice almost all through the day that was the pattern, the Heavyweights were trying to puss the index up and the Mids and Bottoms were pulling it down. Now lets look at another day.

Image 2

This is a sort of range bound day with a mild downward bias, as you can see the HeavyWeights were flat and a bit positive too holding up above the Zero line, where as it was the Minds and the Bottoms who were pulling in the index down.

What I have learnt so far about Index moves is this

1) Constituent Stocks oscillate between the two states of “Convergence” and “Divergence”.

2) The state of “Divergence” can also cause a directional move depending on the strength of the segments and the degree of the move in terms of Price change.

3) We get to see more stronger moves when there is “Convergence”. For instance we may have had an upward trend in the Index in the Morning session, by mid day you may see a Divergence in the segments, for instance say - the Minds and the bottoms are pulling the index down - now there are two possibilities either they (Minds and the Bottoms) converge with the Heavyweights and move up or the Heavyweights converge with the Mids and the Bottoms and move down.

These are pretty much the things which happen in the Index all through the day.

Now the question would be - How does this help in Trading?

1) Looking for developing divergences helps in identifying the beginning or an end of a move. Divergences can start with the Bottoms as well, and in some times the other two segments can catch up.

2) Knowing which segment is in control also helps in making an assessment of the possible degree of the move.

3) Past patterns can be used to predict the future. Machine learning and data science can be of use here.

Hope you found this useful!.

Segmented Cumulative UpVol-DownVol | Making of Trend Days

As traders we are always fascinated by trend days, for novices it a great day, for the ones who trade reversions to the mean, its dreadful.

In this post we look at what happens in the underlying stocks on Trend Days.

The indicator that we have chosen to analyse trend days is a % Cumulative Upvol-Downvol for a Segment of Stocks. There are three segments of stocks that I have taken.

Segment 1 - Top 10 Stocks By Weightage - Constituting (60%) - Solid/Red/Green - Top

Segment 2 - Next 15 Stocks By Weightage - Constituting (20%) - Dashed/Red/Green - Mid

Segment 3 - Next 25 Stocks By Weightage - Constituting (20%) - Solid Yellow - Bottom

So what do you see here?

a) You need the Top Segment to be trending.

b) If the Mid segment goes along with the Top good.

c) Bottom Segment unless makes a massive impact , does not really matter.

Does it matter which Trading Room you join?

Choosing your Trading Room can be as exacting as Choosing your life partner

Are you part of a Trading Room? Or looking at which one to go with but not too confident where to put your money? Well having run a Trading Room and being part of a few well known ones, I’ve come to understand that there are a few things you need to consider before you have your pick.. As they say Birds of a feather flock together, so here’s how to find your nest..going with the bird metaphor!

Your Trading Worldview - What beliefs do you hold dear to you and what are you willing to let go? Gann numbers or Elliot Wave; Market profile/Orderflow or Market Internals? Quant based or Qual based trading...you see where i’m going with this. Seldom have i come across Trading rooms serving all and being good at it. See what aligns with your worldview before joining a Room

photo-1425421640640-64c4debea1b4.jpg

Learning Environment - Telling vs. Learning. Some Trading rooms ‘Tell’ you what trades to take and when, so you are more an implementer of their trading decisions and there are other Trading Rooms which may focus on working through a process that is consistently called out, so you are not just executing trades but also understand the logic behind taking a particular trade. One way to know if it is the later, is to look for consistency in the trading process/rules being followed. Do you understand why a trade was taken or cancelled. How do they rationalize losses? Do they provide reasons?

Metrics & Tracking - What gets measured gets done. Any room that is brave enough to put out their performance chart, every day, consistently , ‘Respect’. Day trading is like any other business, you need to run an end of the day tally, else how would you know which days you do better? whether there is a correlation between your green days and other factors like range etc? Any room which shies away from it , is not being true to the game.

Integrity - Claims vs. Reality. Timing is key here. Tall claims based on Hindsight Analysis are for newbies and seasoned Trading Rooms would stay clear of it and instead would be able to show real time decisions taken in the Room. Bet on that!

Look before you leap - Ask for a trial - any Room that is confident of giving you one, darn sure they know their business. It’s that clear.

Trading Instruments - Jack of all; Master of None. How does that sound? I will be a little hesitant to put my money there. Prefer to work with specialists and experts, in one or two areas . Know your instruments and chose your Trading Room partner. Side note: Did you know : In an Indian context trading Futures makes less sense compared to Options esp. intraday. Just saying, time you get that nuanced in understanding this game.

Trade Setups - What's your Risk appetite?What RIsk Reward ratio are you comfortable with?40 point SL ?30 point SL?10 point SL? And add to that the holding period, and the scene changes completely: Intraday vs Positional or Swing, both approaches have very different risk levels and risk management approaches. Choose a Room that aligns with your Risk appetite ratio

Charting & Live Screencast - This is a kicker. All trading rooms boast of proprietary indicators. Guilty as charged. But hey, there is a method to the madness. Does the Room take the effort to explain these indicator and point out why a certain decision was taken , have user manuals explaining these indicators and finally do they have enough back tested data in support of these indicators..then you have a winner.

Trust this helps you sieve through the noise and pick your Trading Partner. it’s not that you are going to be wedded for life so go ahead and walk down the aisle. Happy Trading.

Putting Losses in Perspective - Structuring a Trading Plan to include the Edge

In the previous post we talked about what an edge is and how do we know if we have one?

If you are beyond that, it means you have crossed a big milestone, as most (90%) of people that I know, can't get past that.

But knowing about an edge is hardly sufficient to make it work. You also need to know how and when to execute trades in the context of that edge. We will not get much into all aspects of execution today, but focus more on the “Rules” for execution i.e the Trading Plan

Think of the following questions before you create a trade plan

  1. What are the prerequisites for you to enter the trade - Meaning what are the the confirmatory elements that you need. It could be defined in terms of factors like - Price Range, Time of the Day, volume levels etc. any measurable variable

  2. Would you wait for a confirmation on all variables or there is a prioritization among them, or weightage.

  3. Would you enter all at once or would you scale in / pyramid into the position?

    1. How much would go in the first tranche and the subsequent?

So you put the trade - and next

  1. What would you do if

    1. You don't get a fill

    2. You get a partial fill

  2. Where would you Stop Loss be?

    1. Is it going to be dynamic or static?

  3. Are you going to Exit in full size or you would scale out in parts?

    1. How would you determine the scale out ratio?

    2. What if the price reaches 90% to your target and does not move beyond? Would you wait for up your Stop loss or Cover?

    3. What would be the buffer/variance where you will cover your trade even if it does not hit the target precisely.

      1. On what basis would you cover or hold?

Having answers for all these questions, answers informed by data i.e. - ought to be your next milestone

Putting Losses in Perspective - Do you have an Edge?

One of the fundamental reasons for losses in trading can be traced to lack of an “Edge”. But then you would ask me what is an Edge?

To me a trading edge is -

An ability to isolate a condition or a set of conditions among a market variable or a set of market variables - that has a non random way to evolve over a specific period of time.

I remember reading somewhere, but I cannot place it where - it said - “If you can’t explain your trading edge, you don’t have one” - Let me take it to the next level

If you do not know the statistical a) probability of the set of (prerequisite) condition/s that need to occur b) the probability distribution of the outcomes once the conditions (a) occur.

If you cannot articulate both then in my world you do not have an edge.

It’s quite possible that you are a veteran and even though you cannot articulate your edge, you have internalized it over a long period of time. But that according to me is a long winded route and I would personally prefer to be in the know of my edge.

So coming back to losses, the reason we need to be able to articulate our edge is - in the event of a loss, we need to know if its a part of our larger probabilistic framework or is it something which is beyond that. We need some objective reference. For example if you have a loss streak of 5 days, you need to know its statistically “normal” in your trading system or is it an anomaly.

In other words, your understanding of the variables of your edge helps you put your trading outcomes in a measurable context.

In the same breadth, it also helps us understand if the market regime itself is changing, and helps us adapt better.

So the next time you make a loss you know who to catch first?

Putting Losses in Perspective | Introduction

“I just want to breakeven”

“I just need to recover my last loss”

“I just need one move in my direction and I will be in profit”

“Let me widen my stop loss I’m sure the price will turn in my favor”

How about these lines?

“I should have stuck to my strategy/my rules”

“I should to have got out earlier with little losses and instead I stuck around”

“I should have closed my trades than choosing to go positional…big mistake”


Sounds familiar? The ongoing chatter in a loss making mind. Sometimes it’s there during the trade and more often, after a loss making day!

As much as we credit ourselves as rational beings capable of making sound decisions, literature proves otherwise. We are just a Rider on the Elephant, and if and when there is a disagreement the Elephant usually wins.

But then in the real world, sometimes it's not just the rider and the elephant, it could also be the terrain, the skills of the rider, or the elephant itself, and a whole lot of other factors.

This is an introductory post of our month long exploration on dealing with losses, we will look at the genesis of losses and what is it that we can do manage, minimize and make peace with it.

Losses in trading can happen due to a lot of reasons, sometimes they can be point one specific focus area like emotions etc? but most often they are combinatorial. It could be emotions plus an infra issue. or execution plus a trading strategy issue.

To look at losses, and to be really at peace with it, you need to isolate the causes, you can make peace with your losses only and only if you are damn sure that it’s a part of your system, and adheres to your trading system’s win/loss rate and size.

Its like this, you have a headache, and you wonder why do I have this headache - on a spectrum of causes, on one end it could be dehydration and on the other extreme it could be a brain tumor. Now for you to be at peace and ignore the headache you need to be damn sure it’s only dehydration and not a malignant brain tumor. (Sorry if that sounds morbid, losses can be equally bad)

Dehydration in trading will be a “loss that is part of the trading plan” and Brain tumor will be everything else.

In the coming weeks Kavitha and I will spend some time on strategies, methods and models to manage losses both behaviorally and financially.


Through the Looking-Glass, & what NiftyScalper found there | Market Internals - Part 3

This is the third and last post in this series,

Part 1 - Here

Part 2 - Here

**Read about what RSI is over here

In this post we will look at the good old RSI Indicator which has been re-purposed to be used as, both a trend indicator and an oscillator.

The math - We took the top 25 stocks (by weight-age) of NIFTY 50 and Averaged their RSI Value. So we have a Average RSI of the top 25 stocks vs. RSI of NIFTYFUT or RSI of 50 Stocks. Since the 25 stocks have close to 80% weight-age the cross over of the Average RSI and NIFTY RSI acts as a trend Indicator.

Notice the RED colored (NIFTYFUT RSI) Crossing over the Yellow Dotted line of (Average RSI).

We also back-tested for ideal Oversold and Overbought levels - you will see it marked with Blue colored markers in the images below. Typically a RSI Absolute Difference of 10 - 12 i.e (NIFTY RSI - Average RSI)

So here you have a Market Internal based Trend Indicator + Oscillator all built into one since indicator.

There are several other setups for trading pullbacks using this indicator, but thats for another day..

Please do not ask for the RSI Period settings on this one, but its no rocket science. Also, at NiftyScapler we don’t use any of these three indicators in Isolation.

Educational Explainers - Lead Lag Effect - NIFTY

Last week we looked at what Indexes are (Over here).

This week we are investigating the lead-lag relationship between Spot price and Future prices in NIFTY.

So what does academic research and years of observing the market tell us? The verdict is out..

Allegory of the Cave, Order-flow and Price Discovery

There is this interesting story called “Allegory of the Cave” by Plato.

The story in a way describes what happens to people when they are blinded by a context and fail to see the world outside of it.

I was reminded of it as I saw my twitter feed yesterday.

Instance one below

Next one here

Both the posts allude to the idea that

a) We spotted big buying at that level thanks to Orderflow.

b) Big buying led to the turn in the price.

Point b) is the key. One needs to get an handle on that, and one needs to ask fundamental questions there.

So the question to ask is -

Did the buying happen because the price turned or the price turned because the buying happened?

Yes, that question sounds a lot like Socrates’s Euthyphro Dilemma.

But let me not deviate.

Back to the question.

“Did the buying happen because the price turned or the price turned because the buying happened?”

To answer this question we will turn to what the researches say,

The idea is to understand the location of “Price Discovery” - If price discover happens in the Futures, then we can say - Price turned because buying happened.

However, if the location of price discovery happens to be Spot/Cash market, then it’s the other way round - Buying happened because the price turned.

So what’s the case with NIFTY, where does Price Discovery happen in NIFTY - Spot or Futures ?

Read this post for the evidence - https://www.niftyscalper.com/blogs/2019/1/21/lead-lag-volatility-spillover-effects-some-evidence-from-academic-literature

Kavitha and I will talk about it in our upcoming Explainer tomorrow.

As I sign out - Don’t for heaven’s sake look at the shadows and imagine a non-existing world.

Lead-Lag / Volatility Spillover Effects | Some evidence from academic literature

One of the most fundamental concepts one needs to understand as an Index Trader is that of Lead-Lag effect. I have been reading through several academic papers to get a grasp of it. Here are some that stood out.

Notice the difference between NIFTY and the other markets, I rest my case here.

Through the Looking-Glass, & what NiftyScalper found there | Market Internals - Part 2

In the previous post here we looked at the NiftyScalper Advanced Relative Strength Indicator which is a Price based internals indicator, in this post we will look at the next piece of the puzzle ie Volume.

If you read about internals for the US Markets you will come across something called NYSE UpVol and NYSE DownVol, more about it here.

Unfortunately our indexes don’t broadcast this info. But what do you do when you need something badly and cant get it, you build it.

Yes, that’s what we did, we created our own NIFTY UpVol-DownVol indicator for the top 25 stocks.

Do note that, instead of a ratio we decided to look at the Net Volumes as we would also get a sense of liquidity/participation along with the direction.

CumValue - Cumulative UpValue-DownValue; CumVol - Cumulative UpVolume-DownVolume

As you can see in the above image, there is a massive net sell in the volumes of the constituent stocks, now follow the price action in the next 30 to 45 minutes. Lets move to the next idea.

Based on a suggestion from a fellow trader and friend Navdeep we came up with a variant of NIFTY UpVol-DownVol which we call NIFTY UpValue-DownValue, here we look at not just the volume but Value i.e Volume * Price. This helps us normalize for situation where the volumes could be skewed due to higher or lower face values of stock prices. It also helps us recognize situations where only a few key stocks try to pull the index up or drag it down.

Look at the image below

You an see there was buying that was initiated, perhaps in a few stocks (quite heavily) hence reflecting in the Up-Down Value but Up-Down Vol remains in the red. As you would imagine this was a narrow range day with a tug of war between a few heavy weights and rest of the index.

As I sign off, I must contend that I these Internals based Indicators have really saved me a lot of head and heartache. I am able to filter out contexts that I don’t want to trade, quite well.

Update: 16th Jan’19

I found a similar spike in the CumVol, this time on the upside as discussed in the first image. Notice the price action after that.

Pullback vs. Reversal | Can Market Internals Help?

Those of you who follow the blog regularly know that we at NiftyScalper have been working on creating tools to look at NIFTY Market Internals as a way of understanding the index moves better.

In this post I will spend some time on one aspect which if learnt can make a massive difference in your p/l.

We will look at understanding what is a Pullback and how do we know that its not going to turn into a Reversal.

What is a Pullback?

A pullback is a micro-counter-trend within a macro trend. Micro and Macro are time references, and for scalpers and day traders it can be 5 to 10 mins for Micro and 45 to 60 minutes for macro.

Pullbacks can be great opportunities to scalp so long as the macro trend continues.

What is a Reversal?

A reversal is a move which starts like a micro-counter-trend move, however does not go back to the initial macro trend and can potentially be the beginning of a counter-macro-trend.

I don’t want to hear your stories as to how many times what you thought was a pullback turned into a reversal, and that was the end of it, for some people I know that was the end of their trading account. Especially if you don’t have your stops in place instead have ‘hope’.

Given such grave and potentially devastating outcomes of what was essentially a misread price pattern, we at NiftyScalper thought why not check if Market Internals can help us with increasing our odds of identifying ‘potential’ reversals.

If you have questions about the market internals based indicator that I am referencing here, read this post.

Look at this image below. If you notice from the point which I have marked with a blue dot, the % of stocks below 1SD of VWAP which is the red line has been inching up, along with price also rising, almost crossing over the green line (% of stocks above 1SD of VWAP). Which is obviously a sort of divergence. From that point onwards, I would be wary of pullbacks as the strength of the move, in terms of the number of stocks supporting it is waning. So this was one way of looking at it.

NIFTY Futures 28t Nov’18

Lets look at this next chart, same day, same time frame. The blue dot is a common time reference across both charts.

The Red and Green line here are from a slightly different Market Internals indicator where we look at Standard Deviations from a 45 Minute Mean Price. As you can clearly see here, this one is far more pronounced, the % of stocks above 1SD of 45 Min Mean has been downward sloping as the price makes new highs and peaks.

You can see or yourself, as the support from internals declines, the probability of a pullback being just a pullback also declined.

To me it looks like there is a story here, something to follow up on.

I will keep you all posted. Till then Trade safe folks!

Finding 'edge' through Data Curation

When we talk of ‘edge’ in trading it essentially means, what is it different that you or your system has which would lead to an ‘alpha’ in terms of returns. One way to extend that question is to ask ourselves, as to what are the sources of that edge?

To me having a more deeper and nuanced understanding of the contexts and setups that I trade, exponentially adds to my edge. To get a better sense of my contexts, one of the practices that has massively helped me in my trading, is curating setup specific data. This is a lot of work, let me tell you. Sometimes it’s very difficult to train the computer to do what we humans can do intuitively, which means a lot of it is manual labor.

Let me try to give you a sense of what I mean, if you follow my blog you would know that, these are the three setups that I trade.

NIFTY - Scalping Set-up - 01 - Opening Spikes & Opening Drive

NIFTY - Scalping Set-up - 02 - Mid-Day Mean Reversion

NIFTY - Scalping Set-up - 03 - Afternoon Range Extension

Now each of these setups have their nuances and details, like

a) At what time did the entry get signaled? Is that time range bound? Is there a seasonal skew to it?

b) Range breakouts on VIX? Time and Amplitude.

c) What is the average size of the pullbacks that in the setups you trade?

d) What is the ideal holding time for your some of your setups, based on the length of the trends?

A lot of these computations are possible only if you have specific data. Therefore, this is a practice that we follow in-house and for our clients - i.e. to capture such data so as to run tests on it.

Here is a mini snapshot of the data. (Disclaimer : The snapshot may make no sense whatsoever without context)

This practice when followed over long periods of time can give you a gold mine of data, which (I believe) can add to your trading expectancy.

ATR (Average True Range) vs. ADR (Average Day Range) | What they don't tell you

I was having this conversation with a coachee of mine, who was bent on using ATR instead of ADR as a reference for trading and I had to help him understand the difference and the context as to what is relevant where, and why I lean towards ADR. Below is an excerpt of what I told him.

The case for ADR

First things first - What is ADR - ADR is simply the average of intraday (High-Low) value. This excludes Gaps.

So - What is ATR? - Here is a better explanation. Essentially ATR is a range calculation which includes Gaps as it calculates from PDC (Previous Day Close).

So it essentially boils down to the significance of Gaps.

Let’s digress a bit to understand why do we use Range as a reference.

To me Range is a good indication (of / or a proxy for) volatility. You will see that for yourself, if you follow VIX, as VIX increases, so does range (Ref. the plot below). By including Gap in the calculation we may get an incorrect and irrelevant view of the intraday volatility.

Based on Past 60 Days’ data - NIFTY Futures and INDIAVIX

As an Intraday trader I am concerned only about what happens between the Open and Close. That is what is my playing field. I am not a positional trader to take advantage of or get affected by Gaps.

So the next question to ask is? Is there a correlation between the size of the gap and the ADR for the day? This would determine if including GAP data helps us in any way.

I did a quick math by calculating the Correlation Coefficient with Gap size as an independent variable and (ADR) Range as a dependent variable and I get a score of 0.36. Take a look at the scatter-plot below.

Based on Past 60 Days’ data - NIFTY Futures

As you can see there is no linearity in there.

So given that there seems to be no correlation between Gaps and ADR, I would recommend using ADR and not ATR,

ATR is relevant in markets or products were Gaps have a correlation with Range, which does not seem to be the case with NIFTY.

However, I do keep an eye on the Gaps, but that is more from a perspective of understanding if there is a visible change in the market structure, more on it later.

Here is a snapshot of the data that I reference during the day. It gives me a clear sense of the developing range with references of Previous day and a 20 day Look back period.

What are Market Internals & Why should you bother?

Before we delve into what Market Internals are, lets ask another question to ourselves - Why does a (Stock Market) Index move?

To understand that we need to move to one level deeper and ask as to - What is an Index?

What is an Index? - An Index is a weighted average value derived from a set of constituent stocks, ie the price of the constituent stocks. So if the prices of the constituent stocks go up the Index which is nothing but an average of those prices would also go up, and the same would happen if the prices of the stocks go down.

In a way we have now answered the question - Why does a (Stock Market) Index move? - An index moves because the prices of the constituent stocks change.

These changes can happen over various time frames. Within a few minutes? Sometimes hours, days, years and so on. But the phenomenon is the same - Prices of Constituent Stocks Change leading to a change in the Index Value.

Now with that sorted, lets move to the concept of Market Internals - Market Internals refers to the data derived from the constituent stocks, which could be used to understand the Index’s structure and strength better.

One way to think of Market Internals is to think of it as Instrument Panels in a Cockpit. If The Aircraft has to fly the way it ought to, all the reading on the instrument clusters need to be within a threshold.

Same is with an Index. If the Index is expected go up then the “Instrument Clusters” ie the Market Internals need to align in a particular way.

Lets take an example -

^NIFTY has 50 Constituents. Their Weight-ages look like this. The top 10 stocks account for close to 60% of the Index, the next 15 add up to 20% more, and the last 25 add up to another 20%.

In other words, being an index with just 50 stocks of which 10 stocks constitute close to 60% of the index makes it a very top heavy index.

This NSE Replica by Equity Master is a nice tool to give you a sense of what they call NIFTY Sensitivity. What it tells us is - For a given change in the price of Stock A how much will the Index Move. Lets look it up for HDFCBANK

For reference lets take the last one on the list HindPetro

HDFCBANK has a 15x more impact on the Index compared to HPCL.

Hope you are with me so far? - We are still exploring what Market Internals are?

Back to where we left.

Lets say you are an Intraday Trader and you expect the market to go from 10600 to 10700 today. A good 100 point move. For such a move to happen? What do you think would happen under the hood? Can HDFC bank be down say by 2% and a few other heavy weights are down or perhaps flat, would we still get a 100 point upside move. As you would guess the chances are quite less.

Like wise what if you see that the top 8 stocks by weightage are all nice and green, trending up - Now what would be the odds of getting that 100 point move? Quite good right.

Lets look at another aspect, what if the trading volumes in the top 10 are quite light compared to its 20 day average? Do you think we would have a trending high range day?

What if the to 10 and the next 15 stocks are going in opposite directions? Do you think we would get a trend day?

I hope you get the drift. Market Internals are these variables or data which are generated by the constituent stocks, analyzing which can help us understand the overall state or health of the market.

If you look at the US Markets esp. NYSE you will see that the exchange broadcasts live Market Internals like NYSE Tick - Which is the number of Stocks Upticking minus the number of stocks Downticking. In lie markets it gives you a sense where in which direction the skew is. This data can be in turn back-tested to identify thresholds of Intraday tops and bottoms. It should not be confused with Advance Decline Indicator which references the Previous Day Close for its calculation. Where as the Tick uses the previous close.

It would look like the one in the image below.

Image Courtesy - RedlionTrader

Second, they have something called NYSE Upvol and DownVol, which is broadcasted as two separate values, but many platforms allow you to plot the difference ie Upvol-Downvol. Which tells us which side is volume skewing i.e How much volume is associated with the Upticking stocks vs how much of it is with the Downticking stocks.

As Intraday Index Traders we in India miss out on this vital informational edge. Not calling it a Holy Grail but nevertheless extremely important to gauge the mood of the market.

As they say what do you do if you cant find what you want? You build one.

In the following weeks we will look at the various Market Internals based Indicators which we have created for our use at NiftyScalper.

Market Profile & Order-flow Charts | Revisited

A few days back I received a comment on the blog about Market Profile and Order-flow as a tool which offers an edge in the market.

Here is the comment.

And here are my previous articles about the same.

Part 1 & Part 2

I thought it’s important to explain to novices as to how the “information flow” in stock market works and which is what is the foundational reason behind price moves in an Index.

Disclaimer: My comments here are only in the context of Indexes and specifically about NIFTY 50 and NIFTY FUT

So let’s start with the basics

What is an Index? - An Index is a Collection of Stocks which are weighed together to arrive at an aggregate value. This weightage is based on market cap of the constituent stocks for NIFTY. If you want to have a look at the constituent stocks and their weight-age, this is the place.

What makes an index move up or down? - Say the average range of the index is 100 points, why does it move so much? It moves because its constituent stocks move. Say for instance if the top 5 stocks by market cap - Reliance, HDFC, HDFC Bank, ITC, Infy etc. move down the market will move down, and visa versa.

Now that we know what is an Index and why does an Index move up or down, lets get to some nuances here.

What is “Information Flow” and what is its relevance here?

Information flow is about the direction of causality for price discovery in a given market. If that sounds a bit wonkish - it essentially means, in the context of an Index, what moves first, and what causes what. Does the future prices move ahead of Spot? or it is the other way around. There are different statistical ways of measuring the the strength and direction of causality, but that is beyond the scope of this post, look up “tests of causality” if you are interested, if you are even more interested look up Judea Pearl’s work. Oops! Sorry for that diversion, back to Information flow and price discovery.

So to repeat, there can only be two types of informational flows

a) (Stocks) Spot -> Index Futures - Spot prices lead Futures

b) Index Futures -> (Stocks) Spot - Futures prices lead Spot

Like everything else, its more about which type of information flow is more dominant in a given market. Its not necessarily binary.

As I pointed out here, for NIFTY its type (a) which is more dominant (Image below from 2) Reference). Which is not true for all markets though, for instance the S&P 500 works on type (b) logic.

If you are wondering as to why does it happen, well there are tomes of academic papers on that, but it boils down to two factors largely, one is cost/barriers to trading in a given product, and relative volumes.

So to sum this point while type (a) is a fundamental reason for index moves, type (b) can also happen and may provide a minor edge to the participants.

Hope you all are still with me.

So far we looked at

1) What is an Index? 2) Why does it move/What causes its moves?

Now lets get to the topic of this blog post.

Market Profile and Order-flow Charts. I will not spend time in explaining the basic concept of Market Profile and Order-flow, that I did in the previous posts, do refer to them for the basics. But here I am going to explain Order-flow more than Market Profile. Both are unrelated but for some reason a lot of sellers and vendors offer them together. Let’s move on.

Let’s understand the process flow of an order, i.e. an order you put to buy or sell one lot.

  • Buy/Sell Order Placed by you ->

  • Order goes to Broker’s OMS (Order Management System) ->

  • Then goes to Exchange’s OMS ->

  • Finally reaches the CLOB (Central Limit Order Book) ->

  • Order now gets queued based on Price and Time priority (Depending on Market or Limit Order type) >

  • Finally once it matches another Buy or Sell order it gets executed.

If you notice I have not used the word order-flow anywhere yet in this sequence of events. The reason being, only after an order is executed we get to see the Order-flow Information i.e. Bid/Ask Volume traded at a given Price.

To reiterate Order-book (LOB - Limit Order Book) comes first and Order-flow later.

^LOB is the information that you see in the Market Depth window of your trading platform

So in a way Order-flow is stale info. Its all done and over by the time you see it (*Assuming what you see is what it is).

If someone claims that there is a “Predictive Edge” in Order-flow they are essentially claiming that “if X volume at bid or ask happens at a given Price” it means the price will go further up or down.

For a second ignore predictive edge, even a statistical edge will do? Show me one Order-flow based back-test and I would be happy to update my views here.

If this is not enough, you also need to understand how Level 1 Data Feeds work.

None of the feeds in India give you tick by tick data, we don’t have the infrastructure as retail traders to receive it, what data-feed providers like TrueData, GDFL and E-signal give is a Per Second Aggregate of Ticks. So what you see in an order-flow is an *aggregate information for a second or as some call it “Snapshot Data”. Which can never be accurate, to put it differently its not meant to be, there will always be “missing” info. in it.

And lastly always ask yourself, if Order-flow info had such an edge, why wouldn’t these indicator sellers keep it to themselves and print money.

Personally, I have used and tested both Order-flow and Order-Book information to the extent it’s possible with retail level latency and infrastructure and have not found any edge there.

So to sum it all up, Order-flow, if at all has an edge, it would be in a market with type (b) information flow, which we are not. And secondly, in markets with type (b) information flow, you might-as-well use Order-book Info. why would you want to look at stale order-flow info.?

This is all I had to share, hope it helps you, saves a bit of your time (by helping you avoid rabbit holes) and more importantly your money.

Behind the ‘veil’ of Price | Indicators that signal market microstructure dynamics | Part 4 of 4

In the first three parts of this series we looked at indicators which give us a sense of the microstructure activity of an instrument. In this last and final part, we will try to put it all in context.

Lets’ start with the first principles, the key to all that we are discussing is to see - if LOB (Limit Order Book)/Microstructure dynamics leads price change? If so, is the lead time ‘tradable’. What I mean here is, if it leads by a fraction of a second, then it’s not easy to trade on that signal, we need a lead time within which we can execute a trade.

Another way of articulating the first principle is - What moves price esp. Index Futures? What is the direction of causality as the academicians would say? Does spot/cash market lead futures or is it the other way round?

The reason it’s important to get a handle on this is, because the tools that one would design or use would need to be completely different.

For instance if the Index Futures lead price discovery, then it makes good sense to use Orderbook/Microstructure information as that would ideally precede the move in price. However, if it’s the spot or the cash market that leads, then you may want to look at indicators that capture the bias within the index constituents.

 If you look at the academic literature that examines lead-lag relationships between index futures and spot, you would find indexes which fall on either ends of the spectrum in terms of their bias, almost all would be bidirectional at some points. It seems the degree of participation from Individual Investors, Domestic Institutional Investors and Foreign Institutional Investors has an effect. I am sure there are many other structural reasons which influence this lead-lag effect.

Evidence for NIFTY suggests a Spot to Futures direction of causality.

 

Now that we have some sense of the direction of causality, I leave it to you figure out, which indicators (in a shorter time frame) would better predict NIFTY Futures. It’s also worth exploring if this lead time between the Spot and futures market is “tradable”.

Behind the ‘veil’ of Price | Indicators that signal market microstructure dynamics | Part 3 of 4

Part 1

Part 2

In this part we will explore the third indicator that I use which helps us in understanding the dynamics that happens in the Limit order-book before large moves, in a way this is one those “predictive” indicators as it signals oncoming volatility a few minutes before it actually does – The Average Bid-Ask Spread.

In the slack room, I call it SOS – No not “Save our Ship” but “Spikes on Spread” – Which indeed is an SOS signal if you have any positions on, as it signals one to be alert.

Before we get to the mechanics of this indicator, one needs to have a basic understanding of how the Limit Order book (LOB) works.

So if you look at the L2 market depth, this is how it would typically look at a given moment (Graphically i.e.)

 

Now let’s see what happens when a Market Order hits the book. In this example a Market Buy Order hits the book.

The contracts marked in Yellow are the one which are consumed by the Market Order. Now do compare the spread in the two illustrations. In the first one we have a spread of 1 and in the second, because of the market order coming in the spreads doubles to 2. Now let’s see what happens next.

As you can see in the above illustration, the limit orders (Bids) come in to fill the spread. This Expansion-Contraction of spread due to market orders coming in can happen and can be observed over different timeframes. But the concept remains the same.

Microstructure academicians also call this the Liquidity Cycle or more specifically the Make – Take Phases

Typically you have shorter “Take Phases” and longer “Make Phases”, which fits in with the fact that we would typically have lesser market orders compared to limit orders.

With theory covered now let’s move to practice.

Look at the NIFTY Futures 1 minute time frame chart (Date – 8th May’18)

On the top pane is NIFTY Futures Price, the second pane has Average Bid-ask spread as a Histogram aggregated for each minute. On the Second pane is a 5 minute (Orange) over 45 minute (Grey) SMA of the Spread, the last pane has Volume rate which we’ve looked at already in part 1 of this series.

If you notice the spread for NIFTY Futures oscillates in a range of 0 to 2.

So how do we use this indicator?

Observe the spread from 12:05 to 12:45 – If you see the price has largely been range bound but the spread moved from the upper band to the lower band – Remember the concept of “Take Phase”?

My conjecture is this is a period where liquidity takers are sort of sweeping the book, the price remains range bound up till the point where adequate liquidity exists, the moment there is an imbalance we see large moves or volatility come in, and as these initial bursts come in, perhaps herd and threshold behaviour takes over causing extensions of these moves.

Since this indicator is like an oscillator with a fairly defined range – it’s easy to spot deviations and be prepared for an upcoming move, however one must remember this indicator does not predict direction all that it does it predict volatility.

As of now I am still testing and collecting data to do back-tests on this indicator, so I do not have any statistics to support my claim, but people in the slack group know – how often I call out an ‘SOS’ and how accurate or inaccurate it turns out to be.

The usual disclaimer applies to this indicator as well – this indicator  is to be used within the context of the market structure and in combination with other indicators discussed in this series.
