Zerodha streak option strategy

How to change quantities of option contracts in an option strategy ?
example i want to back test butterfly strategy , hence i need 2 ATM short PE and 1 OTM above a strike price and 1 OTM below a strike price . in the dynamic contracts there is no option for QTY of any contract

@Streak Can you.

Hi @aldrin_pato

Streak does not currently support ratio spreads where unequal quantities of different legs are required. However, this will be available soon.
