What is rollover in futures and options
Rollover in F&O means closing your position in the expiring near-month contract and simultaneously opening an equivalent position in the next-month contract, to carry your view forward beyond expiry. Rollover percentage is a closely watched metric in the last week of every expiry.
In one line
Rollover in F&O is the act of closing a position in the near-month futures or options contract before it expires and re-entering an equivalent position in the next-month (or further-month) contract, and a high rollover percentage (above the 3-month average) with stable prices signals that traders are carrying their positions with conviction rather than squaring off.

Why futures expire and what rollover solves
Every futures and options contract in India has a fixed expiry date: typically the last Thursday of the month for the near-month, and corresponding Thursdays for mid-month and far-month contracts. If you hold a futures position and want to maintain your exposure beyond expiry, you must roll over: close the expiring contract before settlement and open the same trade in the next month's contract.
The cost of rolling is called the roll cost or roll yield, which is the difference between the near-month price and the next-month price (the spread). If the next month trades at a premium to the expiring contract, rolling a long position costs money. If it trades at a discount (backwardation), rolling benefits a long position. Roll cost is a recurring charge for traders who continuously carry directional futures exposure.
Reading rollover percentage as a sentiment tool
In the last week before expiry, exchanges and financial data platforms publish daily rollover statistics: what percentage of the open interest in the expiring contract has been carried forward to the next month. A high rollover percentage means participants are choosing to carry their bets rather than closing them, which is read as conviction that the trend will continue.
Rollover is compared against the 3-month average to contextualise it. If the Nifty near-month rollover comes in at 80% against a 3-month average of 68%, it signals significantly higher-than-normal position carrying. If prices are rising on high rollover, it suggests long positions are rolling over, which is a bullish reading. If prices are flat or slightly lower on high rollover, it may mean short positions are rolling over, which is a bearish reading. Like all F&O data, rollover is a directional clue rather than a definitive signal.
Rollover in options: a different mechanic
Options rollover works differently because options have no intrinsic obligation the way futures do. An option holder can let the contract expire (worthless if OTM) or close it. If you want to maintain a directional options bet across expiry, you sell the expiring option and buy the same strike (or an adjusted one) in the next expiry. This is called rolling your options position.
The cost of rolling an options position depends on the time value in the next contract relative to the one being closed. Rolling a long call from near-month to next-month costs the difference in premium, plus you are paying for additional time value. For options sellers, rolling a short position into the next month collects additional premium, which is a core strategy in systematic covered-call and put-selling approaches.

Common questions on what is rollover.
When should I roll over a futures position?
Most traders roll over 2 to 3 days before expiry to avoid settlement risk and thin liquidity in the expiring contract on the last day. Rolling too late risks wide spreads and poor execution.
What does 70% rollover mean?
It means 70% of the open positions in the expiring contract have been transferred to the next month's contract. The remaining 30% have been closed or allowed to expire. The significance depends on whether this is above or below the historical average rollover for that stock or index.
Is rollover bullish?
High rollover relative to the average can signal conviction in the existing positions (bullish if prices are rising, bearish if prices are flat or falling). It is one data point read alongside price direction and open interest changes.
What is the roll cost in futures?
Roll cost is the price difference between closing the near-month contract and opening the next-month contract. If the next month trades at a premium, a long position pays a roll cost. If the next month is at a discount, the long benefits from a positive roll.
