I assume I'm "the other guy"? If so what I say about Refcofx accounts and margin calls is 100% correct. I trade a live account. A 150K position, with no stops, will cost you $750.00. If you have $800.00 in your account maximum loss is $50.00. If you have $2000.00 in your account maximum loss is $1250.00. The amount of dollars you put into your trade will not be lost.
