Buildup & Unwinding Analysis tracks the change in Open Interest (OI) per strike to identify position buildup (new positions) and unwinding (position closures). Buildup occurs when OI increases (positive ΔOI), while unwinding occurs when OI decreases (negative ΔOI).

This analysis helps you understand whether traders are creating new positions or closing existing ones, providing insights into market sentiment and potential price movements.

• Buildup (Positive ΔOI): New positions being created - indicates fresh buying or selling activity. High buildup with price movement in the same direction suggests strong trend continuation.
• Unwinding (Negative ΔOI): Existing positions being closed - indicates profit booking or stop-loss triggers. Unwinding can signal potential reversals if it occurs against the price trend.
• Combined Analysis: Compare CE and PE buildup/unwinding to understand overall market positioning and sentiment shifts.

• CE Buildup: New call positions being created. If accompanied by price rise, indicates bullish sentiment and potential upward momentum.
• PE Buildup: New put positions being created. If accompanied by price fall, indicates bearish sentiment and potential downward pressure.
• CE Unwinding: Call positions being closed. Can indicate short covering if price is rising, or profit booking if price is falling.
• PE Unwinding: Put positions being closed. Can indicate profit booking if price is falling, or stop-loss triggers if price is rising.

1. Combine buildup/unwinding with price action - never trade on OI alone.
2. CE Buildup + Price Rising: Strong bullish signal - consider long positions.
3. PE Buildup + Price Falling: Strong bearish signal - consider short positions.
4. CE Unwinding + Price Rising: Short covering - potential reversal or continuation, watch for confirmation.
5. PE Unwinding + Price Falling: Profit booking - potential reversal, watch for support levels.
6. Monitor PCR and Max Pain along with buildup/unwinding for comprehensive analysis.
