Strike Flow is a strike-by-strike analysis tool that tracks call OI buildup, put OI buildup, unwinding patterns, and open interest changes across all strikes in real-time.

For Nifty and Bank Nifty options, it combines buildup/unwinding metrics with volume, OI changes, and price action in a single view. This helps F&O traders identify where fresh positions are building (positive ΔOI) or closing (negative ΔOI) at each strike, making it easier to spot support/resistance zones and market sentiment shifts during intraday sessions.

Call OI buildup (CE buildup) means new call option positions are being created at a strike. When CE buildup happens with spot price rising, it signals bullish momentum from fresh call buying.

Put OI buildup (PE buildup) means new put option positions are being created. When PE buildup occurs with spot price falling, it indicates bearish sentiment from fresh put buying.

Compare CE and PE buildup side-by-side in Strike Flow to understand whether bulls (call writers/buyers) or bears (put writers/buyers) are dominating specific strike levels in Nifty or Bank Nifty.

OI buildup (positive change in OI) at a strike means new option contracts are being created — fresh positions entering the market. This signals conviction in a direction: CE buildup suggests bullish positioning, PE buildup suggests bearish positioning.

OI unwinding (negative change in OI) means existing contracts are being closed — traders exiting positions through profit booking or stop losses. CE unwinding can indicate short covering or profit booking by call option sellers. PE unwinding often signals put option writers or buyers closing their positions.

Strike Flow highlights these changes in real-time across all strikes, helping traders identify where buildup and unwinding are concentrated.

For intraday Nifty options trading, use Strike Flow to identify key strikes with high buildup or unwinding.

• CE buildup + price rising: Bullish signal for long calls or short puts
• PE buildup + price falling: Bearish signal for long puts or short calls
• CE unwinding with price rising: Short covering and potential breakout continuation
• PE unwinding with price rising: Put sellers closing positions, confirming bullish momentum

Important: Always use stop losses — OI data is lagging and should support, not replace, price action and technical analysis.
