FII/DII flow + OI buildup + bulk deals + insider activity. When 3+ agree, the signal is high-conviction.
No single smart-money signal is reliable on its own. FII flow has hedging noise. OI buildup aggregates all participants. Bulk deals are sparse. Insider trades have non-information motivations.
The high-conviction setup is when 3-4 of these streams point the same direction. Cross-verification is the difference between gambling and informed trading.
FII/DII flow: aggregate institutional positioning. Direction signal.
OI buildup: per-F&O-stock futures positioning classification (Long/Short Buildup, Unwinding, Covering).
Bulk/block deals: named-counterparty large transactions. Highest-conviction per-event signal.
Insider activity: SEBI PIT disclosures of promoter and key-personnel trades. Information-richest source.
FII net buying (cash + derivative agreement) + Long Buildup across sector breadth + named institutional buyer in recent block deal + insider buying in size disclosed last week.
When all four align, position size at 2-3x your typical conviction setup. Historical pattern: such 4-stream alignments produce 70%+ favourable outcomes in subsequent 2-4 weeks.
When the four streams conflict (FII buying + OI Short Buildup + recent block deal sell + insider selling), positioning is in transition. Wait for clarity rather than guessing direction.
Most retail F&O losses come from acting on partial signals during transition periods. Patience here pays multiples.
Rare — maybe 3-5 stocks per week show strong alignment. That rarity is the edge; you're trading the highest-conviction setups instead of generic ones.
For index, the four streams collapse to: FII/DII flow (cash + derivative), index OI buildup, broad sector breadth, retail extremes (Client L/S). Same logic, different specific signals.
Yes — OI buildup is the most direct futures-positioning signal. Combine with FII derivative positioning and bulk/block deals on the underlying.
