Proceedings from the sale of cash instruments (including, but not limited to, equities and ETFs) are subject to standard market settlement cycles. While the sale proceeds are credited to your trading account immediately and may be used for trading, settlement occurs on a forward-dated basis in accordance with applicable market conventions (e.g. T+1, T+2 or longer, depending on the instrument and market).
If you submit a withdrawal request prior to the completion of settlement, your account cash balance may temporarily become negative. In such cases, negative interest may be applied to the negative balance for the relevant period until settlement is completed.
