Market order

A market order does not need to specify a price, and it is bought or sold at the current market price.

1. Order time


1.1 Pre-set Orders

Pre-set orders can be placed after the end of the U.S. T day during the post-hours trading session, and can be executed on T+1 day. The pre-paid orders support settings: 1. Valid on the Day or Good-Til-Canceled, 2. Whether to allow Fill outside RTH.

1.2 Trading Hours

EST 09:30-16:00


Singapore Time 16:00-21:30 is the pre-market trading hours for US stocks and 04:00-08:00 is the US stocks post-hours trading hours. Pre-market and post-market orders will be submitted to the exchange for trading.


2. Description and precautions

2.1 When a market order is placed in the pre-market period, the system will freeze the order and submit it to the exchange for trading during the continuous trading hours; although the market order is supported in the post-hours period, it may not be filled.

2.2 Market orders do not guarantee the best execution price, especially when the market changes rapidly, market orders may be executed at a higher or lower price.

2.3 Note that the market order price will be calculated according to the mkt order multiplier * current price, and Moomoo Securities Australia Ltd would change or reset the multiplier in accordance with market situation. Your purchasing power will be reduced accordingly. After the order is completed or canceled, the frozen part of the purchasing power will be released.

2.4 To prevent the execution prices of market orders from greatly deviating from expectations and causing losses, Moomoo AU temporarily deems the liquidity of some scenarios as insufficient and will therefore disable the placement of market orders.
