How to place spread order in nifty options ?
what to do if I have to buy a lot of 10200 PE and sell 2 lots of 9950 PE in nifty with account balance of 1.3 L?

Search for 10200PE and 9950PE and add them to your watchlist, after that initiate Buy/Sell orders just like you do with stocks.

PS: Current margin requirements for this strategy are 1.22lakhs + 12.8k for buying Put. So it won’t be possible to initiate this strategy with only 1.3lakhs.
