In fact, the stock trading systems of Shanghai Stock Exchange and Shenzhen Stock Exchange should already be at the leading level in China in terms of stability and performance. For example, in the Oolong incident of Everbright Securities 13, Everbright Securities reported more than 1 0000 consignments in1second, and the SSE's system did not crash and stop, which proved the powerful processing ability of the SSE system. On the other hand, the problems of foreign systems in recent years are the same.

As for the stock markets of Shanghai Stock Exchange and Shenzhen Stock Exchange, they are actually problems left over from history. In the early days, the stock market was not transmitted by special line or internet, but by satellite, which is why some established securities companies have satellite receiving pots on the roof of their business departments for this purpose.

As for the futures exchange, the advanced nature of the system is also at the international leading level. As for the millisecond market, I personally think it is really useless, because people's reaction speed is really not that fast, and 500 milliseconds and 1 millisecond really have little effect. If it is a simple procedural transaction, it may be of great use to some people.

At present, the processing speed of NGES2, a trading system used in the previous period in China, is 26,000 transactions per second, which is enough to meet the demand at present and in the next 2-3 years. In addition, the trading system used by CICC is also the NGES system of the previous period. Judging from the current trading situation of stock index futures, this system is still no problem.

The exchanges in Dalian and Zhengzhou don't know much about the system, but judging from the performance in these two years, the performance difference is not very big, just a little weak.
