According to Moneycontrol.com analysis by Shubham Agarwal, open interest represents the number of active futures contracts that still exist for a particular instrument and expiry. This metric serves as one of the most useful windows into the futures market, helping traders understand whether price moves are supported by fresh participation or existing positions. However, monthly expiry creates significant challenges as traders close current month contracts while new contracts appear in the next month, fundamentally changing the open interest picture.
As reported by Moneycontrol.com, rolover percentage measures how much open interest has moved forward by calculating open interest in all later expiries divided by total open interest across expiries, multiplied by 100. The analysis explains that monthly expiry is when current futures contracts end, and before expiry, traders can study positions built in that contract. After expiry, these positions disappear from current month data, with some traders closing trades while others shift them to the next expiry through rollover transactions.
According to the analysis, when a stock rises five percent while its open interest rises fifteen percent, this typically indicates that new futures positions have supported the upward move. However, traders must confirm this expectation after expiry to determine whether the trend will continue or lose strength. The report emphasizes that rollover data helps answer whether the trend will persist or weaken following the monthly contract expiry.
As detailed in the Moneycontrol.com analysis, traders should not exit automatically but reduce risk during uncertain market conditions. For long futures positions, traders can buy put options as protection, while short futures holders can purchase call options. The report suggests that if a trader bought a call or put, they can sell a higher call or lower put to recover time value when the trend weakens. Additionally, tightening stop losses is recommended as a risk management strategy.
According to the analysis, rolover is not a perfect prediction tool but a confirmation tool. The report recommends comparing stock or index rollover with the broader market, studying price and open interest together, and avoiding decisions based on single numbers. Rollover data is available on the NSE website, and many options analytics platforms calculate it automatically. This approach helps traders judge whether trends have genuine participation beyond expiry or are ready for a pause during uncertain market conditions.
