Recently, I've seen quite a few discussions about the classic M-top pattern, which is indeed a common reversal signal we encounter during technical analysis.

Speaking of the M-top, it's essentially a double top that looks like the letter "M." During a sustained price increase, it forms two nearby peaks, called the left shoulder and the right shoulder. Theoretically, the two peaks should be roughly the same height, but in actual movement, the left shoulder is usually slightly lower than the right, with a difference of about 3% being quite common.

I've noticed that the most critical feature of the M-top pattern is the change in trading volume. The volume at the left shoulder is particularly high, then it starts to decrease at the right shoulder. This decreasing volume actually signals that the buying momentum is weakening, and the price may be reaching a top. After forming the first peak and then falling back to a low point, we draw a horizontal line across this level, which is commonly called the neckline. When the price rebounds a second time and then falls below this neckline, the M-top pattern is officially confirmed.

As for how to find the best selling point, that's the most important in practical trading. The first opportunity is at the turning point of the right shoulder—many traders will choose to sell here. Honestly, those who can accurately sell at this position are truly "prophets," because the subsequent movement hasn't been fully confirmed yet.

But a safer approach is to wait for the price to break below the neckline. Once the price confirms a break below this level, it indicates a significant downward trend is coming. At this point, selling all holdings is the smartest choice. Moreover, during the decline, the price often experiences a rebound, but the strength is usually weak, and the neckline will act as a clear resistance level.

To be honest, mastering the logic of the M-top pattern is especially helpful for risk management. When you see this pattern appear, you should start to be more alert.
