Thank you very much for the quick support! It seems like my error was caused by setting 5 digit precision instead of 2. Cheers!

Please add it as the BTCUSD symbol as a CFD in order to be able to set 2 digits. Set the other market params.

Please post several lines of your data.

I have followed the docs regards uploading a custom data file (https://forexsb.com/wiki/fsb/manual/data_files), but yet I am still having difficulty using my custom data which is uploaded below. I am using tabs (\t) as the delimiter, DateTime seems to be in the right format and volumes are whole numbers. For the sections of the symbols, I classified Bitcoin as a CFD.

Could you spot anything wrong with my file? I have tried everything:/ Thank you very much!

Kind regards,
Sean.
