Calls to the right in gold, puts to the left in violet, all three on one shared scale. Net is what survives when they cancel.
The first bar is every open contract that exists. The second is only what changed today. Opposite directions mean today pushed against the position rather than adding to it.
Look at the NIFTY pair in Flows. The standing book is short 22,336 Cr of delta while today’s flow was long 50,558 Cr, 226 percent of it, the other way.

NIFTY went into the close short 22,336 Cr of delta. Today's flow was long 50,558 Cr. 226 percent of the standing position, pointing the other way.
- Call wall heaviest call open interest above spot
- Put wall heaviest put open interest below spot
- Gamma levels max gamma strike, zero gamma, the flip
- Close where it actually finished
Open, high and low mean the first, highest and lowest of 111 to 121 samples taken between 09:16 and 15:39 IST, not the exchange’s official prints, and the close is the last price we sampled rather than the settlement price. GEX is normalised to five days and compares across days for one index, never between indices. Volume reads zero at every strike after the close, so no volume figure appears above.
Same time tomorrow.
