In technical analysis, a series of high and low prices for a security that, when plotted on a chart, looks vaguely like a triangle pointed to the right. One constructs an ascending triangle by first drawing a horizontal line on a chart representing a high price toward which a security is approaching and then drawing a diagonal line representing a security's upward price trend. An ascending triangle indicates that both the highs and the lows are rising. It is a bullish signal. See also: Descending triangle.
In technical analysis, a triangle-shaped chart pattern indicating price breaks during periods of high- and low-volume trading and characterized by a left side that is nearly vertical, a top that is nearly horizontal, and a third side that slopes upward and to the right to connect with the left side and the top. This pattern is considered to be a bullish indicator especially when the price breaks upward through the top side on high volume. Compare descending triangle.
