ATH Retracement Levels

### ATH Retracement Levels Indicator

**Overview**
The ATH Retracement Levels indicator is a powerful tool designed for technical analysts and traders seeking to identify key support zones during market pullbacks. By dynamically calculating the all-time high (ATH) of the instrument's price history, this indicator automatically plots horizontal retracement lines at -5%, -10%, -15%, and -20% below the ATH. These levels serve as potential support thresholds, helping traders anticipate price reactions and refine entry/exit strategies in trending or consolidating markets.

**Key Features**
- **Dynamic ATH Detection**: Continuously tracks and updates the highest high across the entire chart history for real-time relevance.
- **Customizable Retracement Lines**:
- **ATH Line** (Green, 2px): Marks the peak price for quick visual reference.
- **-5% Level** (Red, 1px): Shallow pullback zone for early support testing.
- **-10% Level** (Orange, 1px): Moderate retracement, often a psychological barrier.
- **-15% Level** (Yellow, 1px): Deeper correction, signaling potential trend weakness.
- **-20% Level** (Purple, 1px): Significant drawdown level, ideal for contrarian setups.
- **Informative Labels**: On the latest bar, each level displays its precise price value (formatted to two decimal places) with color-coordinated tags for effortless interpretation.
- **Pine Script v5 Optimized**: Built for efficiency with `max_lines_count=500` to handle extended timeframes without performance lag. Fully overlay-compatible for seamless integration with other indicators.

**How to Use**
Apply this indicator to any chart (stocks, forex, crypto, etc.) via TradingView's Pine Editor. It works best on daily or higher timeframes for long-term trend analysis but adapts to intraday views. Watch for price bounces or breakdowns at these levels to inform trades—e.g., buy on a -10% retest with bullish confirmation. For advanced users, the open-source code allows easy tweaks, such as adding more levels or alerts.
