If your trading account is on Cash Upfront basis, your trading limit is almost equivalent to your available deposit minus the transaction costs (i.e. Brokerage, Clearing Fee and Stamp Duty). If your trading account is on collateralised basis, your trading limit will be computed based on 2 times of your available deposit balance plus 1.5 times of your fully paid securities pledged with PM Securities.
Please take note that the transactions costs mentioned above would only be deducted from your deposit when you have successfully transacted buying of shares. Your deposit will remain intact if you do not trade and you may withdraw it at any time subject to two working days’ notice.
