First of all, we must understand the division of trend types in the theory. Trends are divided into consolidation and trends, and trends are divided into upward trends and downward trends. Consolidation is a type of trend and is opposite to the trend. The consolidation trend contains at least one center, and the trend must have at least two centers at the same level but not overlapping. The divergence of the theory is divided into levels. If there is no trend or divergence, it is aimed at trend divergence. To find the trend divergence, the premise is that the trend type must be a trend, that is, the trend must contain two independent and non-overlapping centers. The situation is that the current center is higher than the previous center of the same level without overlap, and the decline is the opposite. Only in these two cases can the trend divergence be compared. The level of trend divergence is the largest, followed by central divergence, consolidation divergence, and intra-segment divergence. The conditions for consolidation divergence to be established must be three strokes or segments in the same direction. The end point of the third stroke or segment must be higher than the end point of the first stroke, and the intensity of the third stroke or segment must be smaller than the first stroke or segment.
