I just opened real account with oanda today. I found their system to allow adding subaccount awsome. No question ask, you can add up to 19 subaccounts !MT4 enabled or FXTrade platform. I tried to execute the orders on the MT4 & found it to be very quick. My current broker asked all kinds of questions regarding my opening of the subaccount (what is the source of my money, what lot size do i plan to trade, what is the frequency of my trades....) I have been with this one since 2005. I am still with them because some how I can still do the hedging which is great for my EA that does this strategy. However, I think it is not their business to ask these questions.
