Open Interest Analysis for Futures

Lesson Content

Open Interest (OI) is a powerful indicator in futures trading that reveals the number of outstanding contracts in the market. Unlike volume, which measures the number of contracts traded, OI tracks the total number of contracts that have not been settled. In the Indian derivatives market, OI analysis is crucial for understanding market sentiment and potential price movements. When OI increases along with price, it indicates new money entering the market, confirming the trend's strength. For instance, during the 2020 market recovery, Reliance Industries futures saw rising OI alongside price increases, signaling strong bullish sentiment. Conversely, rising OI with falling prices suggests aggressive short positions, as seen in Bank Nifty futures during market corrections. A declining OI with price movement indicates positions being closed, potentially signaling trend exhaustion. The OI data can be analyzed at different price levels to identify support and resistance zones. For example, Infosys futures often show significant OI buildup at psychological levels like ₹1500 or ₹2000, acting as magnets for price action. Advanced traders use OI concentration data to identify strike prices where maximum positions are open, helping them gauge potential price barriers. The OI position report published by NSE daily is a valuable resource for analyzing market positioning across different stocks and indices.
