Glad that the program was useful for you. We had many requests to implement Interactive Brokers - a user is working on a plugin as far as I know, but otherwise we'll write an IB plugin as soon as the MT4 interface is ready.
We also heard about FXCM issues, but can not confirm them so far. Their US branch was successfully sued some years ago for asymmetric slippage. We've observed the slippage statistics on our FXCM accounts, but found no asymmetry so far.
Complaints about brokers must be taken sometimes with a grain of salt. Traders especially in the US tend to sue their broker after they lost their money.
