An order flow app for NSE: what TBTflow shows, what it costs, and what it refuses to do

People search for order flow software for NSE and find tools built for other markets, or a list of apps described in the same adjectives. This page answers a narrower question honestly: what TBTflow shows for Indian F&O at tick resolution, what it costs, what it deliberately does not do, and who should not buy it.

What it shows

Who is buying and who is selling, in rupees. Every trade print, signed buyer- or seller-initiated, for about 210 NSE cash stocks, about 208 stock futures and the NIFTY and SENSEX futures. From that: futures order flow in rupees, cash flow with block prints set aside, and sweeps that take several price levels at once. How a trade is signed is explained in how our data is built.

The order book behind the price. Five levels on each side, live, and what happens to them: size added, pulled, or eaten by aggressive trades. Absorption, when heavy aggressive volume meets a price that will not move, is shown as a description, not a call.

Big prints as they happen. An event ledger of single trades above a size floor, with the side that initiated them and whether price moved; a huge print with no price change is labelled a negotiated cross.

The index read three ways at once. NIFTY through its cash stocks, its futures and its options together, with the futures basis, VWAP context, open-interest build-ups and Gamma Terrain for the option structure.

Free, without a card: 17 live price and volume scans behind an email sign-in (the full list), the end-of-day build-up lists, and every expiry recap.

What it costs

₹899 a month or ₹7,999 a year, each with a 7-day free trial, or a ₹1,099 pass. Setting up the trial runs a ₹5 check that is refunded automatically. No broker tie-in, no execution, no commission. Details at /subscribe.

What it deliberately does not do

It does not give buy or sell calls, targets or stop-losses, and it is not registered with SEBI as an adviser or research analyst. It does not place orders. It does not show a reading as an edge until that reading has passed a test written down in advance; the ones that failed are removed.

Who should not buy it

Anyone who wants to be told what to buy, anyone who trades only from a candle chart and will not look at the book, and anyone trading markets outside NSE and BSE. TBTflow is for the trader who wants to see who is doing what on the tape, right now, and decide alone.

How to judge any order flow app, including this one

Ask four questions and expect numbers. How is a trade signed as a buy or a sell, and was that rule tested? How many levels of the book, for how many instruments? Is the data from a live feed or a delayed snapshot? Does the app publish the record of its own readings, including the ones it removed? TBTflow's answers: against the previous trade, tested on live NIFTY futures; five levels for about 420 instruments; live, tick by tick; yes, in how our data is built and on the detector page.
