can anyone recommend the best way to trade fx remotely.i'm currently trading on cme electronically,but will move to brazil in the next 4/6 months and dont want to be reliant on what could be constant delays in connectivity to exchanges.would quite happily entertain the idea of going through a broker or using sites like IB or FXCM,but i know nothing about the former 2.if i choose the broker option,what is a ballpark on rates i should be looking at?any recommendations/criticisms greatly appreciated
