Enhanced Auto Levels & Trendlines

Overview
The Enhanced Auto Levels & Trendlines (EAL&T) is a powerful, all-in-one indicator designed to automate the detection and visualization of key market structures. It combines auto-drawn trendlines, support/resistance levels with volume-based shadows and labels, and auto-flipping Fibonacci retracements/extensions. This tool helps traders identify potential reversals, breakouts, and targets without manual drawing.
Built on Pine Script v5, it uses pivot-based calculations for accuracy and includes customizable options for repainting, extensions, and sources. It's ideal for swing traders, scalpers, and analysts who want clean, dynamic charts.
Key Features
How to Use
Step-by-Step Guide
Add to Chart: Load the indicator. Start with defaults.
Interpret Visuals:
Trendlines: Green (bullish/up), Red (bearish/down). Watch for breakouts – line "breaks" and extends if enabled.
Levels: Horizontal lines with shadows (boxes) showing wick strength. Green above price (resistance), Red below (support). Labels show % buy/sell sentiment.
Fibs: From latest swing low (0.0) to high (1.0). Use 0.5/0.618 for retracements; 1.272+ for targets. Flips automatically on trend change.
Customize for Your Strategy:
Volatile Markets (e.g., Crypto): Increase tl_length to 20+ for fewer false trends. Enable repainting for real-time.
Ranging Markets (e.g., Forex): Set override_source=true, custom_source=close for wick-ignoring pivots.
Fib Focus: Increase fib_extension_bars for longer projections. Hide trendlines if cluttered.
Levels Tuning: Shorten pivot lengths (e.g., 20) for intraday; lengthen (100+) for swings. Set shadow transparency to 100 to hide boxes.
Trading Ideas:
Breakout Trade: Buy on bull trendline break + Fib 0.618 confirmation.
Reversal: Sell at resistance level with high sell% label.
Targets: Use Fib extensions or trend targets for TP; levels for SL.
Combine: Overlay with MA crossover or volume for signals.
Tips & Troubleshooting:
Clutter? Toggle sections off or increase lengths.
No Lines? Ensure show_* is true; check chart history (needs 2x pivot length bars).
Repainting: Normal for real-time; disable for backtesting.
Custom Source: Test on demo – e.g., hl2 for median prices.
Updates: If lines don't extend, verify extend_bars > 0.
