The difference between order cancellation and invalidation

Order Actions: Cancel & Deactivate

1. Cancel

A pending order can be cancelled. To re-place the order, you need to re-enter order price and quantity.


2. Deactivate

To deactivate a pending order means to put it on hold:

-A deactivated order is cancelled from the exchange, but the Futu Trading System still holds its info. 

-To re-place the order, simply reactivate it. The order will have the same price and quantity.
