What you can do here
The flow section selects leading positive and negative OI changes from loaded futures and options, showing up to eight rows on each side in the current source. The four familiar buildup names are heuristics based on the signs of price and OI changes. Every open contract has counterparties; the labels do not identify who opened or closed a directional exposure.
- Read price and OI together for each contract.
- Use the F&O Screener for a selected buildup cohort rather than assuming the additions table is an all-contract filter.
A look inside OI Intelligence
From numbers to understanding
- 01
Price up + OI up is long buildup; price down + OI up is short buildup.
- 02
Price up + OI down is short covering; price down + OI down is long unwinding.
- 03
A reduction alone cannot establish long unwinding without the price direction.
- 04
Check the linked row's expiry and option side; the section is a bounded ranking, not the entire universe.
PUT PRICE DOWN, OI UP
Illustrative walkthroughIllustrative NIFTY 24,950 PE classification: if that exact put's premium falls while its OI rises, the heuristic is SHORT BUILDUP, not long buildup. This rule does not prove the identity or strategy of option writers, and no observed quote is asserted here.

What this does not tell you
Buildup labels are descriptive price/OI rules, not participant identification, a directional forecast or proof that a squeeze has ended.
Analysis, not advice. Past performance does not predict future results. Examples are illustrative; prices, scores and counts may have changed.
