An ascending triangle chart pattern is a chart pattern used in technical analysis that is characterized by a flat upper trend line and a rising lower trend line that converge at a point called the apex. The pattern is typically considered to be a continuation pattern, where the price is expected to make a move similar to the prior trend. Volume typically decreases as the pattern progresses, meaning that traders are becoming less inclined to buy the asset, which could indicate that a breakout is near. Typically, the stock price will break through the upper trend line to the upside, indicating that the trend is likely to continue.
