How to calculate the exchangeable amount?
When you exchange currency from your account, the system will automatically calculate the current exchangeable amount. Factors that affect the exchangeable amount may include the deposit and withdrawal amount, stocks buying and selling, transaction fees, settlement and delivery fees.
For example, if you sell $10,000 worth of shares in the U.S. stock market on a T-Day, the funds in your account will not be available for the exchange until T+2 (position closing day plus two working days due to trade clearing & settlement process).
Users can check the exchangeable amount on the currency exchange page.
