Hello, at present, there are three main futures trading systems, kingstar system, which used to be the mainstream system of futures companies, and now its position is weakening. The fast CTP system is now used by most futures companies. Hang Seng System has always been a minority in the futures market. However, if you have high requirements for the system, you may want to consider the situation of the futures company's servers, whether you can place your own servers, the physical distance from the exchange, and the level of handling fees. Consider everything and do the test first.
