Fractional Share Order Applicable for selected US stocks only

Fractional shares enable you to buy small portions of U.S stock for as little as US$10 instead of the whole share. You can specify a dollar amount that you’d like to spend or receive instead of an amount of shares. You can sell part of a whole share or even part of a fractional share by specifying a quantity with a decimal place. Fractional shares will only be executed once each trading day during the Core Trading Session. Your fractional shares order will be automatically carried forward to the next trading day if the market closes early.

Market Order Available for Hong Kong and US stocks

A market order is a buy or sell order to be executed immediately at current market prices. As long as there are willing sellers and buyers, market orders are filled.

Market orders are therefore used when certainty of execution is a priority over price of execution. A market order is the simplest of the order types but does not provide price protection and may fill at a price far lower/ higher than the current price. Your account may have insufficient funds to settle the market order and may result in a negative cash balance.

Please note that a market order can only be executed in the Continuous / Core Trading Session. For U.S. Market, any market orders placed during the trading halt will not be accepted and any pending market orders during the trading halt will be canceled.

Limit Order Available for US stocks only

A limit order is an order to buy or sell a stock at a specific price or better. A buy limit order can only be executed at the limit price or lower, and a sell limit order can only be executed at the limit price or higher. A limit order is not guaranteed to execute.

Enhanced Limit Order Available for Hong Kong stocks only

Enhanced limit orders (ELO) allow matching of up to ten price queues at a time. Any unfilled Enhanced Limit Order will be put in queue as Limit Order at the same price. Notes: ELO submitted before 09:15 will be automatically sent to HKEX as At-auction Limit Order during Pre-opening Trading Session.

Applicable to eligible stocks of Closing Auction Session (CAS) – unfilled ELO from Continuous Trading Session and ELO submitted during CAS will be automatically sent to HKEX as At-auction Limit Order.

However, the order will be canceled if the price of the buy / sell order is higher / lower than the allowable price limit prescribed for CAS.
