The CISI UAE Financial Rules and Regulations specifies core controls that must be incorporated into a market's electronic trading system. One of the principal controls is the automatic stopping of purchase orders where those orders exceed the limits supported by a broker's bank guarantee or reach the threshold applicable to a special order. Automation is significant because the control must operate at system level and prevent a broker from accepting exposure beyond the financial security available to support its transactions. The CISI material defines a special order as an order approved in advance by the market for a securities transaction exceeding 80% of the amount of the broker's bank guarantee. The requirement is therefore not merely a facility enabling manual intervention, making option A incorrect. The electronic system must also enable listed entities and their registrars to view their own share registers; it is not designed simply to conceal that information. Multiple-investor trading-account provisions are governed separately. Consequently, option B directly reproduces the required electronic-trading safeguard and is the correct answer.
