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) 86515888 to secure further aid or information on your cancellation request.
