@CALLumbus, thanks a lot, I'm going to check them out.
@None Business, sure, overnight they all take the 3600 margin from CME. but intraday a lot of brokers now offer 500 usd margin on NQ, ES, YM. even IB takes just 1800 USD. Tradefutures4Less, AMP, DeepDiscountTrading, almost all that I contacted.
