Introducing Order Flow on FYERS Smart Charts

[cESDZke3Fi (Shashank Singh)]

Hey Anmol

For a trade, the feed gives us the traded price, traded quantity timestamp etc.

Broadly, we look at where the trade was executed relative to the order book at that point, along with a defined approach for trades that fall between the bid and ask. The same inputs follow the same logic, and this is applied consistently across instruments and timeframes.

Your point about the bid and ask moving around the time of execution is absolutely valid. It can have a bearing on the classification, and we account for this deliberately in our approach.

While we’re happy to explain the overall methodology and concepts, we won’t be able to share the exact rule set, including the precise book state used, fallback logic, and handling of individual edge cases. That involves our internal engineering work and is also part of what differentiates our implementation. We’d rather be transparent about that than give you an incomplete answer.

A cosmetic update request. When displaying the Delta display the + or - sign also, similar to cumulative Delta you are displaying. This will make it easier to read irrespective of feature any color theme enhancements in future.

Fixed Range Volume Profile, Fixed Range Market Profile, Session based Market Profile (Daily, Weekly, Monthly), Session based Volume Profile - these tools will make very suitable setup for us. Thank you.

Thanks for the detailed response. I appreciate the transparency regarding the proprietary nature of the implementation.

However, I think there is an important distinction here that needs to be made very clearly.

You’ve confirmed that FYERS receives the traded price, traded quantity, timestamp, etc., and then looks at where the trade was executed relative to the order book and applies a defined approach to classify it as Buy or Sell.

If that is the case, then what FYERS is presenting in the Order Flow charts is not actually Buy/Sell trade data in the literal sense — it is FYERS’ inference of the aggressor side of each trade.

A stronger or more sophisticated inference algorithm does not change that fundamental distinction.

So I want to ask this very directly:

Does NSE actually send FYERS an explicit aggressor-side / Buy-Sell flag for each executed trade — YES or NO?

If the answer is NO, then wouldn’t it be more accurate to describe the Buy/Sell figures in the Order Flow charts as “inferred buyer/seller initiated volume” rather than actual Buy/Sell volume?

For example, suppose NSE reports:

Trade price: ₹100.00
Quantity: 500
Timestamp: 10:15:23.456

If there is no exchange-provided aggressor-side field attached to that execution, then there is no direct information in that trade itself saying “these 500 were buyer-initiated.”

FYERS has to determine that retrospectively from the surrounding order-book state and its own logic.

And this is precisely where the issue becomes important: the moment you introduce an inference layer, the resulting Buy/Sell classification is no longer raw exchange Buy/Sell data — regardless of how good the inference algorithm is.

I completely understand not disclosing your proprietary rule set. I’m not asking you to reveal your IP.

I’m asking for clarity on the nature of the data itself:

Are we looking at exchange-provided aggressor-side data, or FYERS-derived aggressor-side estimates?

Because those are fundamentally different things, particularly for traders using Order Flow, Footprint and CVD analysis to make decisions about actual buying and selling pressure.

I think this distinction deserves to be made explicitly to FYERS users.

Hello Team,

I’m really impressed with the introduction of the Order Flow Chart on FYERS. It’s great to see such useful features being added—keep up the good work!

My trading strategy is based on the 3-minute time frame, so the currently available 5-minute data is not very useful for my analysis.

I kindly request you to consider adding an option that allows users to customize the candle time frame, particularly the 3-minute time frame.

This would make the Order Flow Chart even more useful for traders who follow different time-frame-based strategies.

Thank you for your continued efforts and support.

Best regards,
Pavithra

Hey Rohit, thanks for the kind words! Sharing the link to our support article on Delta and Cumulative Delta, which should help you understand this better,
