Of course it depends on the market. You can compare the time-sharing chart of stock index futures and the market, and you will find that the trend of stock index futures is basically the same as that of the market, but the response is faster than that of the market, so as long as the market judges well, the stock index will run smoothly.

Relatively speaking, it is much easier to judge the market trend than individual stocks, and it is very important to focus on the moving average, K line, trading volume and time-sharing trend, especially the time-sharing trend. To study the time-sharing trend, we should focus on the relationship between the real-time trend of the market and the time-sharing moving average, the range of the market's ups and downs, and the performance in various time periods (many times the market will plummet after 2 o'clock).

For example, the time-sharing chart of the market on March 28th is a classic time-sharing chart. Many times, the plunge follows this trend. After opening, it will slowly fall to the side of the time-sharing moving average, and there will be no big rebound.
