Mainland A shares T+ 1 trade, and there are price limits. Mainly to protect small and medium-sized retail investors, but also to protect the A-share market.

Because A shares have been established for a short time, unlike foreign markets with a history of hundreds of years, they are relatively mature. Of course, it has also been mentioned, but if A shares implement T+0, investors need to mature first.

At present, it is impossible to implement the T+0 trading system in China. China stock market hovered between T+0 and T+ 1, and the T0 system was once realized. China People's Political Consultative Conference has also been proposing to resume T+0 trading in China stock market.

1992 in may, the Shanghai stock exchange implemented the T+0 trading rule after canceling the price limit. 1993 1 1 Shenzhen Stock Exchange also canceled T+ 1 and implemented T+0. 1995 based on the consideration of preventing stock market risks, the trading mode of A-shares and funds in Shanghai and Shenzhen stock markets was changed from T+0 to T+ 1 settlement system, which has been in use ever since.

The influence of T+0 on China market remains to be seen. Before the introduction of stock index futures, many people also had high hopes. Later, it was not as expected, but only reduced market volatility. So the function of T+0 is the same. Whether the stock market rises or not depends on the quality of the company and the real economy, not such tools. For securities companies, it can really increase the fee income. Of course, when they finally have money, the competition between brokers will also intensify. Of course, it is also beneficial. Don't worry, it will be launched sooner or later.
