Do HK Stocks have price limitations?
The Hong Kong stock market does not have a 10% trading suspension system.
However, starting from August 22, 2016, the Hong Kong Stock Exchange has launched a market fluctuation adjustment mechanism (cooling-off period) to prevent extreme price fluctuations caused by major trading errors or other abnormal events and maintain the normal order of the market.
A five minute cooling-off period is triggered if the price of an applicable security deviates more than ±10% away from the last traded price five minutes ago. After the 5-minute cooling-off period, the market will resume normal trading. This volatiliy control mechanism in the securities market is only applied on all Hang Seng Index and Hang Seng China Enterprise Index constituent stocks as well as only applicable to board lot order input during certain periods of the Continuous Trading Session.
Trading Rules
Hong Kong stocks are T+0 transactions, so stocks bought on the same day can be sold on the same day.
Settlement Rules
Hong Kong stocks settle in two business days (T+2). This means for stocks traded today (T), the securities company and the clearinghouse will complete the settlement of funds and stocks on the second trading day (T+2).
Short Selling
We currently do not support short selling of Hong Kong stocks at this time.
