I bought 1 stock of GME company for 290€. 2 days latter, I bought 3 more stocks for 220€.
This averages out to 237,5€ per stock (4 stocks total). If I sell at 268, the profit should be 4*268.99=1075.96€, however on your platform it only shows a profit 104.91€, which is a 17% difference. This can't the forex impact, as this was all done last week.
What explains the difference?
