How To Read Big OI Movement
A practical guide to separating meaningful option positioning shifts from ordinary intraday churn.Most important nuanceBig OI movement is most useful when you read OI change together with price change and timeframe. Large positive OI alone is not bullish or bearish until you know whether traders were building on strength or building on weakness.
Absolute OI Change
The board ranks contracts by the size of fresh open-interest change. That surfaces the strikes where new positioning or aggressive exit activity is concentrated.Buildup
When OI rises with price, that usually signals long buildup. When OI rises while price falls, it usually signals short buildup.Unwinding
When OI falls with price, it often reflects long unwinding. When OI falls while price rises, it often reflects short covering.Bucket Context
Always read the latest bucket against the prior bucket. A strike can look dramatic in isolation while still being routine compared with the rest of the session structure.Terminology Traders Actually Need

Start Near SpotPrioritize the highest-change strikes near ATM and one to three steps away. That is where Indian index option flow is usually most actionable intraday.
Check Both SidesRead call and put tables together. Strong call short buildup and put short covering can tell a cleaner story than either side alone.
Respect TimeframeA 1-minute burst can be noise, while a 15-minute or 30-minute burst often points to more deliberate positioning.
Watch RotationWhen the dominant OI change migrates from one strike to another, the real level of control may be moving even if spot is not yet obvious.
