Read the whole F&O market in one glance.
GammaFlow scans every F&O stock each minute. You see which way breadth is leaning, where open interest is building, and the order-block zones on the stocks moving hardest. It runs in your browser, on your own Angel One account.
What you see every minute
One screen, three panels. Breadth on the left, every stock ranked in the middle, the strongest setups on the right.
Market breadth
Every F&O stock drawn as a line from the open, with the count of advancing and declining names and the leading and lagging sector.
Open interest build-up
Price and futures OI read together, so each stock is tagged as long build-up, short build-up, short covering or long unwinding.
Order-block zones
For the strongest movers, the last unmitigated order block on the 1-minute chart, with VWAP, delta, support, resistance and the nearest liquidity level.
Ranked long and short candidates
Stocks are scored on strength, OI, delta and VWAP hold. The ones that line up on every count are listed with their zone and levels.
Choppy filter
Names going nowhere are set aside on their own, so the ranked lists only hold stocks that are actually trending.
Market X-ray
A second view that plots every stock by price change against OI change, so the four build-up types separate at a glance.

Questions
Do I need an Angel One account?
Yes. GammaFlow reads market data through your own Angel One SmartAPI login. Other brokers are planned.
How do I get a SmartAPI key and TOTP?
Log in to the Angel One SmartAPI portal, create an app to get your API key, and enable TOTP for your account. Both are free.
Does GammaFlow place trades for me?
No. It is a screener. It reads market data and shows you what it finds. Every trading decision and order is yours.
Why does it run in the browser?
So your credentials and market data never sit on our server. The scan runs on your device using your own API session.
Can I use it on my phone?
Yes. The scanner adapts to small screens. A laptop gives you all three panels side by side.
What happens when my plan ends?
The scanner stops loading until you renew. Day passes do not renew automatically. Monthly plans renew on the billing date unless you cancel.
