Hey Taz,
I got a few ideas. First, read all you can since there are quite a few non U.S. factors which affect the
FX market.Second, find a reputable house/platform. When in doubt check with the NFA. www.nfa.futures.org. Click on the BASIC tab and put in the firms' name. I did this myself when checking firms. The one I found and liked/chose was Forex Direct Dealer. They are in New York as a matter of fact and when I contacted them they invited me to come see the operation, which I did. I think you will find the spreads to be competitive and the service to be first rate. The guy I spoke with initially was Tom O'neil. 866-367-3933.
Good Luck. If you have other questions, let me know.
