Hard to say without more facts about the way you trade personally. For low costs, I'd point you towards a broker like CedarFX because they have no commission and decent spreads. Trade245 and Oanda are also good choices, so it may help to compare the 3 and see which you like best.
I use IG Markets and Hugosway can use either for futures spreads wise IG are tighter commissions are lower on Hugo's. Best to do a comparison on both or other options others have cited
None of the brokers mentioned in the last 3 posts offer futures trading. Spam bots are still active i see.
