Recently, while studying technical analysis, I was reminded of the wedge pattern. It seems that many people’s understanding of it still stays at a superficial level. In fact, the wedge pattern is quite useful in actual trading, especially when you want to catch the bottom or exit at the top.

Basically, there are two types of wedge patterns: an ascending wedge and a descending wedge. The ascending wedge looks a bit like a funnel. During an uptrend, the price makes higher highs and higher lows, but the upward momentum slows down gradually, and the two trendlines converge. It appears to be rising, but in reality, it’s a trap—when the price finally breaks below the support line, it often leads to a significant decline. I remember early 2023, that tech stock TechCo formed a clear ascending wedge, which suddenly broke down, confirming the predictive power of this pattern.

The descending wedge is the opposite. During a downtrend, the price makes lower lows and lower highs, but the decline gradually weakens, giving the appearance of a potential reversal or collapse. In fact, the buying pressure is slowly accumulating. Once the price breaks above the resistance line, a rebound usually follows. Gold experienced this kind of movement in early 2024, forming a classic descending wedge, and then it surged significantly afterward.

To judge whether a wedge breakout is genuine, volume is a key factor. During the formation of the wedge, volume usually tapers off, indicating market hesitation. But when the price actually breaks the trendline, if volume increases simultaneously, that’s a more reliable signal. Conversely, if the breakout occurs on low volume, it might be a false breakout, so be cautious of getting trapped.

The duration of the wedge formation is also important. Short-term wedges, formed over a few days, are generally suitable for short-term trading with limited volatility. But if a wedge takes several weeks or even months to form, the breakout tends to be more powerful, making it suitable for medium- to long-term traders.

In practical trading, when an ascending wedge shows a bearish signal, I consider shorting when the price breaks below the lower trendline, with a stop-loss just above the recent high. The target price can be estimated based on the height of the wedge—measure the distance from the breakout point downward equal to the wedge’s height. For descending wedges, I go long when the price breaks above the upper trendline, with a stop-loss below the recent low.

However, honestly, although the wedge pattern is a common technical formation, it’s not foolproof. Sometimes false breakouts happen, so it’s best to confirm with other indicators like MACD, RSI, or candlestick patterns. Market conditions also matter; the overall trend can influence the effectiveness of the wedge.

In summary, the wedge pattern is a useful analytical tool that can help identify potential reversal points. But successful trading ultimately depends on risk management and understanding the broader market context. Relying solely on one pattern is not enough.
