So the TOTAL GAIN in the gain column is different than gain as set in the input field "Min % Guaranteed Gain"?

Because as soon as I set "Min % Guaranteed Gain" to 0.4% it warns me: "Risk to trade at a loss" (because the fees are 0.2% + 0.2%), which means that 0.5% guaranteed gain is only 0.1% total gain. But you wrote that the gain in the TOTAL GAIN column (in the gain tab) is the final gain where no fees need to be subtracted from.
