Triangle Pattern Detection [Dots3Red]

Triangle Pattern Detection Indicator detects and draws triangle chart patterns in real time. The indicator identifies pivot highs and lows, validates converging trendlines, calculates the mathematical apex, and classifies each pattern by type.

How it works
The indicator scans for pivot highs and pivot lows using a configurable lookback length. Once two valid pivot highs and two valid pivot lows are found, it verifies that:

The trendlines are genuinely converging (spread shrinks from left to right)
No bar between the pivots violates the trendline boundary
The upper and lower patterns are aligned in time
The pattern meets minimum and maximum width requirements

If all conditions pass, the apex is calculated mathematically as the exact intersection point of the two trendlines, and the full triangle is drawn from the shared start bar to the apex.

Pattern Types Detected

Symmetrical Triangle — both lines converging toward each other
Ascending Triangle — flat upper resistance, rising lower support
Descending Triangle — declining upper resistance, flat lower support
Rectangle — both lines near horizontal

Visuals

🟡 Electric glow triangle
▼ / ▲ Pivot markers at pattern boundaries (commented out in the code)
🔵 Bullish breakout signal / 🔴 Bearish breakout signal with glow effect and stem line
Number label at each triangle's start for cross-referencing with the info table

Info Table (top right)
Keeps a record of the last 5 detected triangles showing:
Column - Description

ID - Triangle number
Type- Pattern classification
Width - Pattern width in bars
BO date - The day the price broke out from the triangle pattern
Status - Live breakout status — Bull / Bear / Inside

The Status column updates on every bar so you can see in real time whether price has broken out of any recent pattern.

Settings

Pivot Length - Sensitivity of pivot detection (1–10). Lower = more patterns
Max Pattern Width - Maximum bars between first and second pivots
Start Bar Alignment Tolerance - Max distance between the start of the upper and lower pivots of the triangle's sides
Max Apex Distance - How far ahead the apex can project
Min Pattern Width - Filters out patterns that are too narrow to be meaningful
Breakout Threshold % - How far the price must close beyond the trendline to confirm a breakout

Notes

All triangles are drawn on the last bar only, avoiding repainting of historical patterns
Breakout detection scans from the leftmost bar of the pattern to the apex, firing on the first confirmed close beyond the boundary
