Hello, I'm a TS brokerage ( RJO Brien ) customer and I would like to know if someone has experience about futures spread margin application on TS. I am trading an inter commodity spread( index futures ) and on my reports i have something like a 700 $ margin overnight whereas i have a 6200 $ margin on my platform's trademanager. As it seems, the reduced margin is applied as soon as the two legs are entered. If I want to trade a new system, I just have to provision the biggest margin of the two new instruments I want to trade( even if my platform is saying that i don't have the cash ), am I right? Should someone that is trading spreads on TS help me? Thanks a lot.
