Hi Surdo, how does buying T Bills affect the margins. Will that reduce your buying power, even if you close all positions before the end of the day? What if you do carry some position overnight, how is the margin determined ?
You keep 95% of your BP. For example, If you buy a 100K T Bill, you still have 95K worth of BP . The word margin is really not used in Futures, it's called "performance bond". The amount of performance bond/contract is not changed. http://www.tradestation.com/Futures_Margin/report.pdf
If you want the T Bill for BP in your TS account, you must call The Desk. If you want to buy 'em at Auction for FREE, you can do it via Fidelity or Treasury Direct electronically.
