The first step is to look at the positive column and the negative column. The positive column represents the trend direction, the positive line is generally red, indicating that it will continue to rise, and the negative line is generally green, indicating that it will continue to fall. Take Yangxian 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's mechanics theorem, in the absence of external force, the price will still run in the original direction and speed, so the positive line indicates that the next stage will continue to rise, at least to ensure that the next stage can be inertial.

Step two, look at the shadow line representing the turning point signal. The longer the shadow line in one direction, the worse it is for crude oil to move in this direction, that is, the longer the upper shadow line, the worse it is for oil prices to rise, and the longer the lower shadow line, the worse it is for oil prices to fall. Take the hatching as an example. After a long and short period of struggle, the Bulls were finally defeated in the last quarter. Once beaten, twice shy. Whether the K-line is yin or yang, the upper shadow line has already constituted the upward resistance in the next stage, and the oil price is likely to be lowered.

The third step is to see that the size of the entity represents the internal motivation. The bigger the entity, the more obvious the trend of spot crude oil price rising or falling, and the opposite trend is not obvious. Take Yangxian as an example, its entity is the part where the closing price is higher than the opening price. The larger the positive line entity, the greater the strength, just like the physical principle that the greater the mass and speed of the object, the greater its inertia impulse. The larger the Yangxian entity is, the greater its internal upward momentum will be, and its oil price upward momentum will be greater than that of Xiaoyang entity.
