Understanding Hong Kong Stock Codes and Board Lots
Use the correct HKEX security code, identify vendor suffixes, and calculate order size using the security's current board lot.
Stock-code formats
Hong Kong securities are identified by numeric stock codes. Data providers may pad codes with leading zeroes and append an exchange suffix.

How board lots affect an order
A board lot is the standard trading unit assigned to a security. The number of shares per lot can differ between securities and may change after corporate actions.
Estimated order value = share price x shares per board lot x number of lots
Broker fees, levies, taxes, currency conversion, and odd-lot execution can change the final amount.
Before placing or comparing an order
- Confirm the exact security code and instrument type.
- Look up the current board-lot size using HKEX or your broker.
- Check whether your intended quantity is a board lot or odd lot.
- Account for Hong Kong dollar pricing and transaction costs.
- Review recent splits, consolidations, and other corporate actions.
