There are two instances when this might occur:

1. You might be trying to cancel your order during the pre-open or pre-close period. Orders cannot be cancelled or modified during Pre-Open period between 9:15AM to 9:30AM and during Pre-Close period between 11:58AM to 12:00PM.

2. The order that you posted may have already been filled or done. Click on the TRADE/PORTFOLIO tab then click on TRADING HISTORY, then fill up your requested details under Order Details and press the SHOW ORDERS button to confirm your transactions.

* Note: If neither of the two seems to be the cause of your inability to cancel, please call our helpdesk at (632) 6-515-888 to secure further aid or information on your cancellation request.
