The descending triangle pattern in trading is a bearish chart formation that can be used to predict a potential downward movement in the price of an asset
This pattern is formed over time as an asset’s price makes lower highs (this forms the sloping top line — or “resistance”) but struggles to fall below a certain level, which creates a flat bottom line. This flat line is known as the “support level” because the price seems to be supported there and doesn’t drop below it.
The descending triangle pattern is generally considered a continuation pattern rather than a reversal pattern. Continuation patterns suggest that the existing trend is likely to continue after a period of consolidation. In the case of an ascending triangle:
Existing Downtrend: The ascending triangle typically forms during a downtrend, with lower highs indicating waning buying interest.
Consolidation Phase: The pattern represents a period of consolidation where the price encounters resistance while forming lower highs. This suggests a temporary balance between buyers and sellers, despite the shrink in the balance.
Breakout Confirmation: The pattern is confirmed when the price breaks out below the horizontal resistance line. This breakout is seen as a signal that the buying pressure has lost to the selling pressure, and the downtrend is likely to resume.
Key Characteristics
Downward Sloping Upper Trendline: This is formed by connecting a series of lower highs. It shows that sellers are gradually able to push the price lower, indicating increasing bearish sentiment.
Horizontal Lower Trendline (Support): This is a straight line that connects the series of lows that occur at a similar price level. The support line indicates a price level where buying interest is consistent and strong enough to prevent the price from declining further.
Converging Trendlines: The downward sloping upper trendline and the flat lower trendline converge as the pattern develops, creating a right-angled triangle that points to the right.
How many ‘valleys’: If you consider a pair of through and peak as a ‘mountain’, then you should wait for at least 2 to 3 valleys to appear as part of the patterns before proceeding to your next step.
Formation period: There is no specific minimum or maximum. Generally, the whole pattern would usually form between a lower limit of 7–10 weeks and could go at an upper limit of a few months.
Trading Volume: Typically, the trading volume diminishes as the pattern develops. A significant increase in volume is often seen when the price eventually breaks below the support level, confirming the pattern.
