1 minute k-line chart?
1 min k line of course represents the opening price, closing price, highest price and lowest price of this minute. The method of judging is the same as looking at hour K-line, day K-line and week K-line.

The validity period of the signal displayed on the one-minute K-line chart is too short. Generally, the trend can only be shown after a few minutes, at most ten minutes. It is of little use for making T+ 1 stock market, but it can be used as a reference for making T+0 futures or warrants.

K-line can be divided into daily K-line, weekly K-line, monthly K-line and annual K-line, and the trading time in one day can be divided into several equal parts, such as 1 minute K-line, 5-minute K-line, 15-minute K-line, 30-minute K-line and 60-minute K-line. These K coins have different functions.

In fact, the truth of all K-line charts is the same, that is, the starting and ending price ranges of a time period are made into entities, with the high starting price as the negative line and the low starting price as the positive line, and then the upper and lower shadow lines are made at the highest and lowest prices of the time period.

One-minute K-line means that the price of the first and last second is a K-line entity, and the highest price and lowest price of this minute are all K-lines made by upper and lower shadow lines. Everything else is the same.
