Intraday broker assisted Margins are BS to say the least, brokers who use them are usually theives.
CBOT sets the margins NOT the brokers.
Ive spoken to many people who've used the small fake broker assisted margin only to not be able to get out by close and lose the lot due to the brokers platform having no connection etc and getting margin called.Oh what a coincidence.
Ive never seen any long term real profitable results using such small capital.
