I really have never entered the forex arena, but I'm interested in downloading the data and seeing how it works with my current systems for futures and stocks. But I see action on these suckers all the time. like for the US stock markets you want to trade from 930 to 400 EST. is there a rule like that for forex trading??? also, other question how liquid are these things? can you day trade them realistically without slippage killing you? 1 min ? 5 min ? 15 min? also, I'm on tradestation downloading forex data. WHy is volume 0???
