In UAE financial markets, certain order attributes can be modified after submission while keeping the order active. According to the CISI UAE Financial Rules and Regulations on Trading, thevolumeof a previous order is the feature that can be changed without invalidating the order. Adjusting volume allows traders to increase or decrease the quantity of securities to be traded without withdrawing and resubmitting the order. However, changes to share category, market, or order type typically require cancellation of the existing order and placing a new one, as these changes affect the fundamental nature and execution venue of the order. This flexibility in modifying volume supports market efficiency and helps traders respond swiftly to changing conditions while maintaining order validity.
