Iron condor exit?

Hi, how to exit an option strategy like iron condor in zerodha, as it has 4 legs, do we need to buy and sell each position

You can exit your open Options positions from Positions tab, click on position you want to exit and click on Exit option this will square-off your position.

So each position has to be exited separately right

Yes, you will have to exit one-by-one. Also, if you are tight on funds, you can exit Short positions first and then exit Long position.

Does zerodha have any portal to practise live without money

Sensibull offers Virtual Trading feature, you can check it out.
