It was only today that I discovered that there has always been a difference in the exchange rate between deposits and withdrawals in windsorbrokers. However, when withdrawing funds, it did not tell how much of the withdrawal fee will be charged, and it is useless that the page shows how much will not be charged. The withdrawal application a few days ago arrived in the account today, and it was found to be inconsistent with the application amount. Originally, windsorbrokers didn't have an app and only had one webpage, and it was often impossible to log in. There will be slippage and network lag when I encountered big fluctuation of windsorbrokers.
