We have an account that recently had a withdrawl for 95% of the deposit. Firstly, it shows as a loss and does not reflect the withdrawl. Second, it shows as a 30% loss not as 90% or more which if you look at the numbers is what it should be. The account is here: https://www.myfxbook.com/portfolio/drs-5/13387
If someone would like to suggest my fx book to fix this bug it is a major one, considering most of the users of this site are interested in system performance, and it is not being calculated correctly.
