this has probably been discussed before but i trade fx cash through gft. I have been paper trading the russell and s&p and wanted to start trading so i figured i would trade the fx since it is suppose to be less expensive . What are the disadvantages to future. From what i read slippage is a big thing.? Can you control the slippage with limit and stop orders instad of market orders? Any comment would be appreciated. Also is the jpy and gbp very liquid in the daytime trading hours?
