Clean Pivot Lines with Alerts

12 ส.ค.

Technical Overview

This Script is designed for detecting untouched pivot highs and lows. It draws horizontal levels only when those pivots remain unviolated within a configurable lookback window and removes them automatically upon price breaches or sweeps.

Key components include:

• Pivot detection logic: Utilizes ta.pivothigh()/ta.pivotlow() (or equivalent via request.security for HTF) with parameterized pivotLength to ensure flexibility and adaptability to different timeframes.
  
• Cleanliness filtering: Checks lookbackBars prior to line creation to skip levels already violated, ensuring only uncontaminated pivots are used.
  
• Dynamic level tracking: Stores active levels in arrays (highLines, lowLines) for continuous real-time monitoring.
  
• Violation logic: Detects both close-based breaks (breakAbove/breakBelow) and wick-based sweeps (sweepAbove/sweepBelow), triggering alerts and automatic teardown.
  
• Periodic housekeeping: Every N (10) confirmed bars, re-verifies “clean” status and removes silently invalidated levels—maintaining chart hygiene and avoiding stale overlays.
  
• Customization options: Supports pivot timeframe override, colors, line width/style, lookback length, and alert toggling.
  

Utility

This overlay script provides a disciplined workflow for drawing meaningful support/resistance levels, filtering out contaminated pivot points, and signaling validations (breaks/sweeps) with alerts. Its modular design and HTF support facilitate integration into systematic workflows, offering far more utility than mere static pivot plots.

Usage Instructions

1. Adjust `pivot_timeframe`, `pivot_length`, and `lookback_bars` to suit your strategy timeframe and volatility structure.
2. Customize visual parameters as required.
3. Enable alerts to receive in-platform messages upon pivot violations.
4. Use HTF override only if analyzing multi-timeframe pivot behavior; otherwise, leave empty to default to chart timeframe.

Performance & Limitations

- Pivot lines confirmation lags by `pivot_length` bars; real-time signals may be delayed.
- Excessive active lines may impact performance on low-TF charts.
- The “clean” logic is contingent on the `lookback_bars` parameter; choose sufficiently high values to avoid false cleanliness.
- Alerts distinguish between closes beyond and wick-only breaches to aid strategic nuance.

WHAT’S NEW

• []Historical Break/Sweep Lines: when a pivot is broken or swept, a dashed historical line is plotted and kept visible for a user-set number of bars.
  []Customizable: length (bars to keep), separate colors for break and sweep lines.
  []Organized Inputs: grouped into Pivot Detection, Pivot Line Appearance, Alerts, and Historical Lines for a cleaner UI.
  []Auto-Cleanup: historical lines expire automatically after their set duration; old pivot levels still cleaned periodically.
  
• Core Logic Preserved: original pivot detection and alert conditions remain unchanged; optional higher-timeframe pivots via “Pivot Timeframe”.
