I am currently trading spot forex, and am considering switching over futures. I just have a couple questions for fx futures traders. I realize that the futures gets you the 1256 election where as on the spot side its not likely. That is why I am considering switching. I mainly trade GBP.USD, EUR.USD AND USD.JPY. I am trying to do a basic comparison as if i trade 100k lots of the currencies, would one contract of each be the similar equivalent to the spot forex trade sizes. Also is there much liquidity to move in and out of 100 futures contracts? Also I know it's crazy to expect to use or get 1% margin as you do in fx, but what is the expected amount for futures?
