According to clause 3.9 of the “Regulations on Non-Trading Operations,” withdrawals must be made using the same method that was used to fund the trading account. If funds were deposited via a bank card or electronic payment system, the withdrawal should be made through the same method, in the same proportion as the funds were deposited into the bank card or electronic payment system. The profit earned during trading is also divided proportionally based on the amounts that were deposited using different payment systems.
