The Investor Identification Regime (HKIDR) is a regulatory measure implemented by the Securities and Futures Commission (SFC) on 20 March 2023.

Mox has to:

Mox currently provides HK and US equities (including stocks and ETFs) trading and also funds investment. Mox customers can place buy and sell orders for HK and US equities, and trade selected funds via the Mox App.

When you place a limit order (to buy or sell), you input a specific price in the order such that, if the order executes, the execution price will not be worse than the specified limit price.

For limit orders, orders will be valid until the end of next quarter (e.g. an order placed on 15 January will be valid until 30 June).

A market order is an order to buy or sell at the market bid or ask price. Market orders may increase the likelihood of the order being filled and the speed of execution, but do not guarantee a specific execution price (and may execute at an undesirable price). If you would like greater control over the execution prices you realise, please submit your order using a limit order, which is an instruction to execute your order at or better than the specified limit price.

When you place a market order, you don’t need to input a specific price in the order. Your order will be automatically matched against the best price available in the market to execute your order.

For placing a buy market order, we will mark-up up to 3% of the stock’s market price (for the US market) or 9 bid-ask spreads (for the HK market) to calculate the buying power required for initiating the order.

For market orders, orders will remain valid until market close on the same day.
