Recently, I have been reviewing some classic bottom patterns and found that many people still have a somewhat vague understanding of the arc bottom pattern. In fact, this pattern is especially likely to appear in the late stages of a weak market trend. I myself only truly understood its power through multiple practical experiences.

The arc bottom pattern looks like a pot bottom, and I think this analogy is very fitting. After the price has fallen for a long time, the decline speed gradually slows down, and then it begins to oscillate repeatedly at low levels. If you connect these repeated low points, you will see a downward-curving arc shape, which is the formation process of the arc bottom pattern.

I noticed a very obvious feature of trading volume during the entire formation process. Initially, the volume gradually diminishes, as if market participation is decreasing, and neither bulls nor bears are eager to engage actively. Then, as the price begins to rebound, the volume slowly increases, and this process itself presents an arc shape. This combination of volume and price is actually an important reference for judging whether the pattern is genuine.

Regarding the selection of buy points, I summarized three key positions. The first is when the price effectively breaks above the neckline; this is an aggressive entry opportunity, but the risk is relatively higher. The second buy point appears at the first pullback after the price breaks the neckline; if support can be confirmed at this time, the success rate will be higher. The third buy point occurs when the price rises again and breaks through the previous high, indicating that the trend has become relatively clear.

Based on my observations, the longer the arc bottom pattern takes to form, the greater the subsequent upward potential tends to be. Some patterns may take several months to fully develop, but once broken through, the subsequent gains can indeed be substantial. However, this also means you need patience and should not enter too early. The best approach is to wait until volume clearly increases and the price effectively breaks the neckline before entering, making the risk more controllable.

A friendly reminder: investing inherently involves risks. Although the arc bottom pattern is a relatively reliable bottom reversal signal, no pattern is 100% accurate. It is recommended to combine other technical indicators and your own risk tolerance when operating, and avoid blindly chasing highs.
