some suggestions for $6000 amount,
tadafulfx [run EA with all default settings, it will open your first lots size will be of 0.05]
alpari-uk [you may set first_lots_size=0.04 OR 0.06]
forex.com [you may set first_lots_size=0.04 OR 0.06]
Prime4x [you may set first_lots_size=0.04 OR 0.06]
actually I want to invest $12000 more in forex market but in another a/c. So if I deposit $6000 in existing FXCM a/c, then only $6000 will be left. Can you suggest a broker to open an account with $6000. I want to use Aeron EA on this a/c too.
