Trade quantity

According to Hong Kong Stock Exchange (HKEX) trading rules, the minimum trading unit is ‘one lot’. Depending on the stock, this can vary significantly in quantity, from as few as 10 shares to as many as 100,000 shares. Most lots fall within the HK$1,000 to HK$10,000 price range. 

Minimum bid size and forced order range: 

The minimum price change, or bid size, for a stock depends on its share price, with specific increments ranging from HK$0.001 to HK$5, depending on the price bracket the stock falls under. The forced range is +/- 9 spreads away at the time of the order.
