The margin call top-up shall be 30% of the total value of the funds invested by an investor through a margin account with a participating bank. An investor shall settle a margin call on the settlement date (as determined by the BSE) by making a cash payment of such amount to the participating bank. Such cash payment may, at the investor's discretion and in whole or part, come from the sale of the securities bought through the System, or otherwise. Failure to meet such margin call will, however, give the participating bank the right to sell the securities bought through the System.
