Overview
Head & Shoulders S/R Regular identifies potential pattern structures by scanning pivot high and pivot low points according to user-defined left and right bar settings. Retracement levels, shoulder height tolerance percentages, and head-to-shoulder proportional ratios filter valid pattern formations. The script draws lines and fills to outline detected support and resistance levels. Because pattern confirmation relies on pivot points with a right-bar delay, patterns are plotted retrospectively once fully formed.
- Automatic Head and Shoulders pattern detection
- Pivot point calculation with adjustable left and right bars
- Support and resistance line fills
- Retracement and shoulder height tolerance filters
