Descending Triangle Break
A descending triangle is a bearish chart pattern that is the opposite of an ascending triangle. It has a horizontal lower trendline and a declining upper trendline. This pattern indicates that selling pressure is increasing as the price makes lower highs. The horizontal support level shows that buyers are still interested in the asset at that price point, but the declining resistance level suggests that sellers are overwhelming buyers. A breakdown below the lower trendline is considered a bearish signal, indicating that the price is likely to continue its downward trend.
Across 30 scored detections, the Descending Triangle Break moved the way it predicts relative to SPY 33% of the time over the next 20 trading days, with a mean excess return of -5.46%. A coin flip scores about 50%.
