What should be the order of execution if I have less margin?

Suppose if I have 60k in my account and if I want to setup iron condor with 1 lots. To setup iron condor I have to buy sell OTM calls and puts 1 lot and buy further OTM calls and puts same quantity.

So if I have less margin should I buy the options first and then sell it or the order doesn’t matter? Also are there any strike price range restrictions on zerodha where we can buy or sell options?

Where can I calculate approximate margins as per new framework?

If you have less capital and what to get margin benefit beforehand, you will have to execute Buy leg first and then Sell leg and while squaring-off exit Sell leg first and then exit Buy leg.

You can check margin requirements on Margin Calculator.

There are no strike restrictions for shorting options, there are restrictions on Buying options and allowed strikes are shown on Margin Calculator page.
