Your withdrawable balance is the sum of any remaining funds that was transferred in, but have yet to be used for trading, plus settled cash from sell orders and dividends.
Kindly note that any cash that is required for corporate action elections, and bonuses credited to your account are excluded.
If you had recently executed a sell trade, there is a 2 business day settlement period before you can withdraw the funds - this applies to both SG and US markets.
Once the settlement period has been completed, your withdrawable balance will show the full amount that you can withdraw. Please note that weekends and public holidays are not considered business days.
Additionally, funds that have been recently transferred may be subject to a credit hold or withdrawal restriction and cannot be withdrawn.
