Next session's playbookobservations, not recommendations

24,200 is the level that matters below.

The heaviest near-money put base (13.3M contracts) sits there; acceptance below it changes the range.

WATCH — first-hour behaviour at 24,200, put OI at that strike

24,500 caps the move until it doesn't.

The call wall holds 6.8M contracts. A close above forces it to migrate; a fade there is the base case.

WATCH — call OI at 24,500: build = cap, unwind = release

Dealer gamma sets the day's texture.

Net gamma +7,098 (Low Gamma). Positive dampens swings, negative amplifies them.

WATCH — net gamma sign at close

Participation has to match price.

Advance/decline closed 203/290. Two consecutive contradictions of the index direction is the early warning.

WATCH — A/D net, delivery breadth

Follow the futures positioning, not the headlines.

FII net index futures at -262,712 — 6th percentile of the year. Direction of change matters more than level.

Method notes. Breadth figures are the IVAAN Breadth Index, a proprietary composite measured across the NIFTY500. Advance/decline and 52-week extremes computed on the same universe. Options metrics are near-money captures for the nearest expiry — consistent day-over-day, not full-chain. FII/DII cash is NSE settled category turnover (T+2); the most recent session may use the combined provisional feed. Dealer gamma from IVAAN positioning aggregates at the end-of-day snapshot. Percentiles vs the trailing 252 sessions unless stated. This brief is market observation, not investment advice.
