Off market orders, or "overnight orders" are orders made outside market hours and extended hours trading and are queued and fulfilled either at or near the beginning of extended hours trading or at or near the market open, according to your instructions.
Off market orders are placed in the same way as regular orders, except that the orders states are in the "waiting for submission" status.
Investors can place off market orders after the end of the trading hours. These orders are saved by Moomoo MY's trading system and automatically submitted to the exchange after the market opens on the next trading session.
