Good find DdlV... BUT, it should be noted that FXCM charges an extra fee for MT4 accounts (I believe it is 0.1 pip per trade). Therefore, it is worth your while to fill out the paperwork for multiple accounts.

If I use Zorro on FXCM, I had planned to use only the web-based TradeStation. I wonder if that would have the same issue as the standalone (ie, take up an API slot)?
