Recently, while analyzing the charts, I was reminded of the classic pattern, the wedge shape, which is indeed a very practical tool in short-term trading.

The most critical feature of the wedge shape is that the upper and lower trendlines must clearly converge, and the direction should be consistent. My personal experience is that if the pattern is too loose, and the trendlines do not show a clear convergence, it can generally be judged that this is not a wedge, and it is likely to develop into other consolidation patterns. Therefore, when looking at wedges, the first thing to confirm is this tight convergence characteristic; otherwise, it’s easy to fall into traps.

There is a common point of confusion that needs special attention—the wedge shape and the triangle look somewhat similar, but their trend implications are completely different. The distinguishing method is actually simple: the two trendlines of a wedge slope significantly, either upward or downward, while triangles are different. If you find one of the sides approaching horizontal, it is most likely a right-angled triangle pattern, not a wedge.

Another practical judgment is that if an ascending wedge appears during a downtrend, be cautious as it might just be a rebound wave, not the first wave of a bullish trend. At this point, it’s even more important to carefully observe the subsequent bearish movement and not be fooled by the rebound.

In summary, wedges are suitable for short- to medium-term trading strategies, but only if you clearly understand their structural features, especially the tight price fluctuations and obvious convergence of trendlines. Mastering these details will be quite helpful in short-term operations.
