When doing your tax returns, they'll use the files showing the dates of the trades made, not the days settlements go through. You'll probably remember that your accountant wants the CSV file, and certainly won't be using the data from the money transferring in and out of your trading account (this would be a nightmare since many people use the same account to pay bills, buy groceries, receive funds from multiple sources, etc). This is certainly an easy question to ask your accountant if you want to hear it from a qualified professional rather than an anonymous nobody like me!
