2. Good-Till-Cancel

2.1 The order will continue to be effective until the order is fully executed, cancelled or the order fails. Investors can place a pending order at an ideal price in advance.

The maximum order period is maintained at 90 natural days and order will be automatically cancelled after the deadline.
