Hong Kong Futures Automated Trading System (HKATS) is the electronic trading system for the HKEX derivatives market. Trading is conducted via workstations or Open Application Programming Interfaces (OAPI) located at the premises of Futures Exchange Participants and Stock Options Exchange Participants.
HKATS provides real-time data such as traded price and quantity, day high/low, turnover, price depth and order depth. Users can view real-time price information on a computer screen, click on a bid or ask price and execute an order.
With HKATS, Exchange Participants can provide their clients with full electronic order routing, straight-through trade processing and other value-added services, and also supply detailed information such as the exact time of order placement and execution.
The Hong Kong Futures Exchange began introducing electronic trading in November 1995, when open outcry trading was still the main trading method among international derivatives exchanges. The electronic trading system was subsequently upgraded and was renamed HKATS in April 1999. Since then, there have been a number of upgrades of the HKATS hardware and software.
