When placing a pending order, investors can choose its validity period, i.e. time-in-force. Choices include Day and GTC (Good-Til-Canceled).
A Day order is active until market close, and unfilled orders will be cancelled after market close.
Note: For stocks/ETFs, unfilled orders will be canceled after market close, i.e. 4:10 PM.
2.1 A GTC order remains active until it is fully filled, cancelled or fails. Investors can place a pending order at an ideal price in advance.
● Unfilled orders will be cancelled after market close, and when the Pre-opening Session begins on the next trading day, will be queued and submitted again to the exchange as an at-auction limit order for pre-opening auction.
Keep in mind: If an order is submitted at a price deviating from the current best bid or ask price by 24 spreads, it will be rejected by the HKEX and fails, and a new order need to be placed.
● A GTC order remains open for up to 90 calendar days, and will be cancelled automatically after expiration.
