OK
> I didn't realize that the accumulated interest would show under "shorts".
Actually report consists of 3 columns:
first column represents results of your ACTUAL SYSTEM
second column represents "LONG-ONLY" side
third column represents "SHORT-ONLY" side.
If you have set "LONG" only positions in the settings then 1st and 2nd column would be the same.
THIRD column ('shorts only') will show ZERO trades but... interest earnings are still in place :
you place NO SHORT trades but the money is on the account that earns interest rate.
Best regards,
