F&O contract close

Hello sir
I have brought Tata motor in April future stock today is last day of contract but I have not sell the stock still. It still showing on position. Till how long able to trade.
Plz advise

That contract will expire tonight

Tomorrow u wont see it in positions

Also, best to exit as taxes are higher for derivatives whihc are allowed to expire.

As a general rule, always square off ur derivatives before expiry.
