Hey guys, I was curious if anybody knows where I can find information from common brokers on their short option on futures margin requirement. I know the common calculations with stock, but I was under the impression that, with commodities, the short option margin requirement is equal to that of the equivalent future underlying. i.e. 1 WTI Crude Oil future has an initial margin of $8100 and a maintenance margin of $6000. Would a corresponding 1 lot of options have the identical margin requirement (or less)? Most brokerage shops are scummy, so I imagine they wouldn't make it much less, but it wouldn't make sense to have it be more than this.
