Allow option to add the funds we have in our account and the margin we would like to use. Like suppose in actual i have 50 lakh in my broker account and i want to trade only for 4 lakh today and i will add the fund available in my strategy and in that you will give option to select 25% or 50% margin to be used from the funds added in the strategy so accordingly the option strike price will be calculated and that much order only we executed.
