If you are trading equities full time & want to nibble spot forex, I will say IB offers flexibility of minimum US$ 20k/30k spot forex size. Even though Oanda I heard is very good for pure forex traders, at IB you dont need to split your capital.Every thing stays in one a/c to take advantage of all kind of markets. I do agree with one poster that Forex futures (during US time) is the best trading vehicle. I would not touch any spot forex broker with a barge pole. I have traded spot leveraged forex with big banks in Singapore &Hong kong like DBS,UOB,Hang Seng bank,Dah sing bank etc. ( Read no internet platform ,Only phone orders& spread not 2 pips may be 7-8 pips for deals less than US$ 300k) But money is safe. Transfer from savings/current/FD /leveraged spot forex/bullion a/c etc is easy done over phone! But today I prefer IB for stock,futures,options& spot forex. I guess(pray!) up to $1 million deposit is safe with them(even though customer service may not be that fast) This observation is useful for full time equity/option traders who want to try spot forex. Not for full time spot forex traders.
