Consider the case of margin required for a Nifty credit spread (positional) and if the orders are placed as CNC Market, the margin required in account from Fyers calculator is as given below.
The problem here is unless the order is executed, the margin benefit is not obtained.
Take the case of Zerodha however. The order of execution of the legs helps there.
As given below if SELL leg is executed first we need a margin similar to what Fyers requires.
However, if the BUY leg is executed first, the margin benefit is considered as given below and amount required in account comes down.
Please confirm why are the margin policies different for Fyers?
