Bottom line: While in the past their margin was equal the max amount at risk in the trade, their new method does some weird calculation and pairs up my trades in a strange way, this gets complicated because I had a partial butterfly roll, so it is locking down more money than I could potentially lose if we were to expire beyond my B/E. I have to review my trades and adjustments now for the impacts on margin as well as the impacts on total capital at loss. More complexity to take into account as I want to utilize the most of my capital and use cash-secured puts or covered call on the cash that is sitting in the account.. in order to maximize I need to study this further..
