Many retail traders focus only on price charts while ignoring one of the most valuable indicators available in the derivatives market—Open Interest (OI). Although price action reveals what the market is doing, Open Interest provides insight into how traders are positioning themselves. When analysed together, these two indicators can help identify stronger trading opportunities and reduce the chances of acting on false market signals.

Open Interest represents the total number of outstanding futures or options contracts that remain active. Unlike trading volume, which counts the number of contracts traded during a session, Open Interest reflects positions that are still open. Rising Open Interest generally indicates that new positions are entering the market, while falling Open Interest suggests that existing positions are being closed.

Indian-Share-Tips.com Nifty Expert Gulshan Khera, CFP®, who is also a SEBI Regd Investment Adviser, observes that Open Interest becomes significantly more valuable when interpreted together with price action rather than in isolation. Retail traders who combine these indicators with volume, support and resistance, option chain analysis and disciplined risk management are generally better positioned to identify higher-probability trading opportunities while avoiding many common market traps.
