Right-Angled Broadening Triangle
An inverted triangle pattern where one of the boundary lines is horizontal, and the other is diverging from the horizontal line. In other words, if the latter line were extended to the left, it would meet the horizontal line.

This ascending right-angled broadening triangle was formed on a 60-minute chart of Rada Electronics. While a line connecting the bottoms is flat, connecting the tops can be performed with an ascending trendline. The cyclical pattern of the stochastics oscillator, plotted above the chart, could confirm the substance of the area pattern.

This daily chart of Microsoft exhibits a descending right-angled broadening triangle, as the price tops between August and early November can be connected by a horizontal line while connecting the bottoms can be achieved with a descending trendline. Breaking out of the patterned occurred when the stock price broke above the $115 mark in mid-November, and has continued its upward movement to nearly $175 as of January, 1999.

In this case, the upward penetration was confirmed by the Commodity Channel Index, or CCI, which broke above +100 for the first time since before the beginning of the pattern in early July.
