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. Live market data is included. No broker login, no API keys.

Simulated session for illustration. In the scanner each line is a real F&O stock, updated every minute.

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 a broker account?

No. Live market data is included in every plan and in the free trial. You only need an email address.

How does the free trial work?

The first time you sign in with an email, you get 30 minutes of the full live scanner. No card needed. One trial per person.

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.

How fresh is the data?

Prices and open interest refresh about every 15 seconds during market hours. The order-block maths runs on your device, so it stays quick.

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.
