First of all, Yin and Yang: Yin and Yang represent the trend direction. The positive line indicates that it will continue to rise. The negative line indicates that it will continue to fall. Take the positive line as an example. After a period of long and short struggle, the closing price is higher than the opening price, indicating that the bulls have the upper hand. According to Newton,

Mechanics theorem. Without external force, the price will still run in the original direction and speed. Therefore, the positive line indicates that the next stage will continue to rise. At least, the inertia of the next stage can be guaranteed.

Secondly, the size of the entity: the size of the entity represents the internal motivation. The larger the entity, the more obvious the upward or downward trend. On the contrary, the trend is not obvious. Take Yangxian as an example. A solid is a part where the closed position is higher than the open position. The more entities in the positive line,

It explains the physical principle that the higher the mass and the faster the speed, the greater the rising power and the greater the inertia impulse. The larger the Yangxian entity, the greater its internal rising power, and its rising power will be greater than that of the entity.

Xiaoyang line How to treat spot crude oil price trend chart? In the same way, the larger the Yinxian entity, the more sufficient the downward momentum.

Length of the last shadow line: the shadow line represents the turning point signal. The longer the shadow line in one direction, the more unfavorable it is for spot crude oil to move in this direction. That is, the longer the upper shadow line, the more unfavorable it is for the spot crude oil price to rise. The longer the shadow line, the more unfavorable it is for the spot crude oil to fall.
