What is Triangle Pattern Indicator?
Triangle Pattern Indicator draws converging triangle formations from recent swing structure on an MT4 chart. Rising and falling boundary lines make the displayed formation easier to review against the surrounding candles.
Labels, fills, and marks are optional display elements. The package includes an .ex4 file and the drawings are chart annotations rather than a fixed expectation about the next move.
How to use Triangle Pattern Indicator
Review the converging lines with the related swing highs and lows. The displayed formation can be compared with candle range, surrounding levels, and the broader chart context.
ShowSemafors, ShowTriangles, FillUp, ShowMarks, ShowAlert, ShowAlertTr, Width1, Width3, BarsCount, DATA1, and copy are available in the Inputs dialog. Use the visibility settings to keep the chart readable.
Where it helps
Triangle boundaries make the displayed swing compression easier to inspect.
Labels, marks, fills, and line widths can be adjusted independently.
Alert settings do not change the formation drawing itself.
