Triangle Formation Theory

Ascending Triangle

The ascending triangle is a bullish pattern, which gives an indication that the price of the security is headed higher upon completion. The pattern is formed by two trendlines: a flat trendline being a point of resistance and an ascending trendline acting as a price support.

The price of the security moves between these trendlines until it eventually breaks out to the upside. This pattern will typically be preceded by an upward trend, which makes it a continuation pattern; however, it can be found during a downtrend.




Descending Triangle

The descending triangle is the opposite of the ascending triangle in that it gives a bearish signal to chartists, suggesting that the price will trend downward upon completion of the pattern. The descending triangle is constructed with a flat support line and a downward-sloping resistance line.

Similar to the ascending triangle, this pattern is generally considered to be a continuation pattern, as it is preceded by a downward trendline. But again, it can be found in an uptrend.
