Brothers who follow orders, if you trade in and out quickly, my suggestion is to set up a reverse fee system.

My initial capital was 3000U, and as a result, in half a month of trading, the reverse fee income was over 3000, meaning the fee refunds have already recouped the principal.
Sometimes, if the profit and loss haven't reached the break-even point, I will cut losses, so at least you can lose less or even not lose because of the fee refunds.
