Strikes with unusual 5-minute volume bursts — and whether that flow looks like fresh opening positions or churn.
What Options Activity shows
Unusual options activity for NIFTY, BANKNIFTY and SENSEX — the strikes whose volume is bursting right now. Raw volume alone is misleading, because the at-the-money strikes always dominate it. This page instead compares each strike's 5-minute volume against that strike's own recent run-rate, surfaces the outliers, and then pairs each burst with the open interest change behind it to tag whether the flow looks like fresh opening positions or two-way churn.
How to read it
- Volume burst — how many times the strike's normal 5-minute run-rate is trading. A 10× burst at a quiet OTM strike says far more than heavy volume at the ATM.
- Character — the burst's classification — opening flow when volume arrives with an OI build (new positions), churn when volume spins without OI following (intraday scalping, rolls).
- Strike and side — where the flow hit and whether it favoured calls or puts — bursts clustering on one side of one zone is positioning, scattered bursts are noise.
- Session context — when the bursts landed. A cluster into a level break reads differently from one drifting through lunch.
Frequently asked questions
Volume that is large relative to that specific strike's own recent behaviour — not large in absolute terms. Every strike gets its own baseline run-rate, and a burst means trading is running well above it in the last few minutes.
Because raw volume rankings are always topped by the same at-the-money strikes, every day, telling you nothing. Normalising by each strike's own baseline is what lets a genuinely anomalous OTM strike surface above the permanently-busy ATM.
Not by itself. A burst can be hedging, rolling or churn. That is why each burst is tagged with its open-interest character — fresh opening flow with a directional OI build is the pattern worth investigating, and even that needs price context before it means anything.
