the reason i ask is that I have 90% of my risk capital tied to a trade that i like much, don't have much capital to do the HKD trade. I want more leverage since i really see excellent risk/reward in HKD. the crappy thing is the retail FX spread which eats up a lot of the potential profit.
It takes very little margin in Interactive Brokers to do it as a forex trade.....much much more to do it as an ETF trade....
