Usually, the recovery high point line is close to the level, and the low point of the rear gear line is gradually raised, thus forming an upward diagonal line. At the end of the sorting form, with the expansion of attack energy, the probability of upward breakthrough is generally greater. The price shows strong selling pressure at a certain level, and then falls back when it rises from a low point to a certain level. However, the purchasing power of the market is still very strong, and the price rebounded immediately before returning to the last low point, and the price kept narrowing with the fluctuation of the resistance line. If we connect each short-term fluctuation high point, we can draw a resistance line; And each short-term fluctuation low point can be connected with another upward diagonal line to form an upward triangle. In the process of formation, the transaction volume is decreasing.

The shape of the falling triangle is just the opposite of the rising triangle. The price has a stable purchasing power at a certain level, so it will rise every time it falls back to that level, forming a horizontal demand line. However, the selling power of the market is constantly strengthening, and the high point of price fluctuation is lower than the previous one, thus forming a downward inclined supply line.

The rising triangle is one of many consolidation patterns, and it is a continuous pattern, that is, the market outlook will continue the previous trend.

The descending triangle is also the performance of the contest between the long and short sides, but the strength of the long and short sides is opposite to that shown in the ascending triangle table.

This form is very common at present.
