Triangle Class

A triangle is a chart pattern used in technical analysis. Like trendlines, triangles may be drawn on charts by using a drawing tool or by using EasyLanguage code.

The Triangle class draws a triangle by connecting the specified vertices with lines. The triangle's appearance can customized using the Triangle's properties (see below).

The Triangle's vertices can be DTPoints, BNPoints, or XYPoints. Triangle vertices specified as BNPoints or DTPoints will maintain their positions relative to the bars on the chart. Triangle vertices specified as XYPoints, on the other hand, will maintain their position relative to the chart's borders. Example code is provided below that illustrates all three ways of specifying a Triangle's vertices .
