Sorry, i read Bitstamp instead of TRT 
Actually i'm not able to get any error (i'm loading markets with statistics and open some market and loading market explorer).

You can try (but don't forget to disable this option because it will write a log of log on your disk) to activate the option "Tool -> Preferencies -> Print Api Call Results to Api Console"

Then all the TRT responses will be printed into the General Console -> API LOG.


This is the message from an external process that checks if the algorithm is running correctly, this means that something went wrong during lookup routine.

You can check
- Market Error Log (Logs -> Error Log Tab)
- General Console (But you already told me that no error was written)
- A File inside CATSystem folder called CAT_LOG (this is usually the extreme way to get errors that occurs and CAT is not able to handle)
