I hate to admit this since I believe Oanda would be the bucketshop from hell, however their FX Manager is really simple for client and manager.

Some MT4 MM's now have http://www.alpari-idc.com/en/metatra...-terminal.htmlsoftware, other MM's have PAMM (Percent Alloion Management Module) and LAMM (Lot Alloion Management Module).

Interactive Brókers have Friends and Family, I have forgotten the name of account today, adviser something or manager.

Out of all of them I discovered FX Manager the easiest.
