Next session's playbookobservations, not recommendations
1
24,000 is the level that matters below.
The heaviest near-money put base (6.2M contracts) sits there; acceptance below it changes the range.
WATCH — first-hour behaviour at 24,000, put OI at that strike
2
24,200 caps the move until it doesn't.
The call wall holds 9.3M contracts. A close above forces it to migrate; a fade there is the base case.
WATCH — call OI at 24,200: build = cap, unwind = release
3
Dealer gamma sets the day's texture.
Net gamma +15,208 (Stabilizing). Positive dampens swings, negative amplifies them.
WATCH — net gamma sign at close
4
Participation has to match price.
Advance/decline closed 301/198. Two consecutive contradictions of the index direction is the early warning.
WATCH — A/D net, delivery breadth
5
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.

Compiled from 215M+ observations · IVAAN, StratLab's market context engine
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.
