Let's talk about these terms first, and take some time to read what I wrote about how to apply them.

These terms are all in the trading trend. Futures, stocks, gold, securities and all financial products.

Yang line: it is a rising candle line. For example, for the daily line, (4 hours, the same as the hour) means that the price at the opening in the morning is higher than the price at the closing in the afternoon, no matter how you go from the opening to the closing, that is to say, no matter how long the upper shadow line and the lower shadow line are, as long as the closing price is higher than the opening price, this line is the positive line.

Yinxian: On the contrary, the closing price is lower than the opening price, which is the lower shadow line.

Upper shadow line: the candle line is divided into three parts: take the positive line as an example: upper shadow line, lower shadow line and entity: the upper shadow line is the entity of the positive line, and the highest price is the upper shadow line of the candle line.

Undershadow line: On the contrary, the lower part of the solid is the lowest point of the candle line.
