What the big overnight moves are tied to
Exposure, not a forecast: markets that moved 0.75 % or more, and the Indian F&O names linked to them.
- Nikkei 225 +1.17 %: Japan is the first large Asian market to trade each morning, a read on regional risk appetite.
- Brent +1.49 %: Crude oil is a cost for oil marketing companies (BPCL, HINDPETRO, IOC), paints (ASIANPAINT) and airlines (INDIGO), and revenue for producers (ONGC, OIL).

Slow builds under the daily gate — positioning facts, resolution pending.
Criteria: |dOI|>=3.0% and |dPx|>=0.5% day-over-day; dOI = TOTAL futures OI (near+next series) net of the daily cross-sectional median, so reads are market-relative and roll-neutral; streak = consecutive sessions same read; RVOL vs 20d avg volume; range_pos = close within 30d low-high; intraday = open-to-close body vs overnight gap. Watch list = 2-day cumulative OI build >=4% that stayed under the daily gate. Data, not recommendations.
