Can you explain why it has this offset? What's special about these fees compared to all of the other fees that are not showing up?
The gains report is calculated for your trades only.
That's why it's taken into account all your trades and trade fees.
But it's not calculating transactions fees at this moment.
I will add them soon.
That's why your data will result in a gain of $1 because according to your data, 0.01 DASH has a value of 1 USD:
A> Type: Trade | Buy: 1 DASH | Sell: 100 USD | Fee: | Comment: Bought 1 DASH from Exchange A
D> Type: Trade | Buy: 100 USD | Sell: .99 DASH | Fee: | Comment: Trade .99 DASH for 100 USD on Exchange BI will try to add tx fees in the next 2-3 days to the gains report. This will solve tx fee offsets.
