The cash capital at risk in the trade is around 18k and any given time. The margin is irrelevant because I have not exceeded my cash available...it's a cash trade.
OK I'll write it like you would. The worst week last year would have been: Max 1 week DD 191 Mar6, 175 Mar15, loss $-1482, Premium $631, realized gains $116 results in net realized loss $-735 Premium calculated from date assigned to date called out.
No it isn't. All margin means when you actually have the capital to cover your trades is how much extra money you have to trade with. Until you have used up your cash it is irrelevant. The cash at risk was about 18k. The profits were 16k. Do what you want with it. Honestly capital at risk is a misnomer. Capital at risk is only relevant when there is substantial risk...it's more return on capital.
