Hi,
I was tring to understand options margin requirements for IB.
Calculating this requirements is not very straightforward. See links below

I tested some options strategies with Zorro and I think this requirements are not followed as I haven't received any margin call errors. Looks like the margin taken into account is just the option price.

Does anyone know a way to make a good approximation while backtesting zorro strategies ?

Has Zorro plan to implement a better margin calculation for options ?

Any help appreciated.

Good trading to everyone
Vincenzo
