Thanks. For the next course of action, please do this every day or every two days, for instance when you're anyway checking your account:
Click [Stop], then click [No] for not closing open trades and [No] for continuing trading. Zorro will log out, close the broker library, then open it and log in again.
Check if you then ever get a "No Data" message again. If not, we'll provide a mechanism that closes and opens the FXCM API automatically. Otherwise we really have to wait for the fix by FXCM.
