Bollinger Free Bars

Identify Extreme Price Actions with Non-Overlay Visualization
Core Functionality This indicator detects two types of Bollinger Band breakout patterns without cluttering your chart: 1 ️⃣ Half Breakout Bar (Blue Triangles)
- Triggers when both open & close prices are outside the Bollinger Bands
- Suggests strong directional momentum continuation
2 ️⃣ Complete Breakout Bar (Red Flags)
- Activates when entire price action (including wicks) stays outside the bands
- Signals extreme volatility exhaustion points
Feature Highlights ◾ Smart Band Display Translucent bands (#2196F3 & #FF9800 with 70% transparency) maintain chart clarity while showing dynamic volatility ranges
◾ Parameter Customization
- Adjustable period (default 20) & deviation multiplier (default 2.0)
- Selectable price source (close/open/high/low)
◾ Statistical Validation Based on Bollinger Band's 95.4% price containment principle, signals filter out 4.6% extreme market conditions for high-probability scenarios.
Recommended Usage
1. Combine with volume analysis (significant breakout with high volume increases signal reliability)
2. Confirm with trend lines or RSI divergence
3. Adjust transparency via "Style" tab for multi-indicator layouts
Code Safety
- No repainting: All calculations use historical price data only
- No external network requests
- Open-source logic compliant with Pine Script v6 standards
Disclaimer This tool is for technical analysis education only. Past performance doesn't guarantee future results. Always validate signals with fundamental analysis and proper risk management.
