ROLL OVER OF FUTURE OF CONTRACTS is like we carry forward in accounts
The futures market the price movements can be quite volatile and erratic. If the prices are moving up rapidly one day, there are chances that they might go down the next day.

A futures contract is all about predicting the future price movements of the stocks. Since the market is so volatile, many a times the prices might not move in the expected direction. In such a scenario, traders participate in a ROLLOVER to avert potential loss.

Any futures contract in the Indian stock market expires on the last Thursday of every month. These contracts usually get squared off or exercised on the last day at the price prevailing in the market. However, if the trader feels that there is too much loss to be incurred and does not want to exercise the contract, he can choose to rollover. This mean they can opt to carry forward the positions or enter into a similar contract expiring at a future date.

Say a trader holds 100 long futures contracts of XYZ Company expiring on the last Thursday of October. If he decides to rollover, he will square off his position and buy 100 futures contracts of the same company. However, the new contract will expire in November.

Rollovers usually start a week before the expiry date, and can be done until last minute of the market hours on the expiry day, While many traders opt to rollover on the day of expiry, it is not mandatory.
