Custom Fibonacci Support & Resistance Lines

Custom Fibonacci Support & Resistance Lines automatically plots dynamic 0.618-style Fibonacci levels based on recent swing highs and lows.

The script detects the latest confirmed swing high and swing low on the chart and calculates two adaptive lines:

A Fibonacci Support Line below price (retracement from swing high to swing low).

A Fibonacci Resistance Line above price (retracement from swing low to swing high).

Both levels are smoothed using a simple moving average for a cleaner visual appearance — similar to an adaptive support/resistance band that follows recent market structure.

⚙️ Features

🔹 Auto-detects swing highs & lows using left/right bar pivots.

🔹 Adjustable Fibonacci levels for both Support and Resistance.

🔹 Adjustable smoothing length for smoother or more reactive lines.

🔹 Works across any timeframe and instrument.

🔹 Ideal for spotting potential reversal zones, trend continuation areas, and dynamic price support/resistance.

🧮 Default Settings

Fibonacci Level (Support) = 0.618

Fibonacci Level (Resistance) = 0.618

Left/Right Swing Bars = 5 / 5

Smoothing Length = 3

💡 Usage Tips

Combine these dynamic Fibonacci lines with trend indicators (EMA, RSI, or structure breaks) to confirm entries.

Increase Left/Right Swing Bars for stronger structural pivots on higher timeframes.

Change Fibonacci Levels (e.g., 0.382, 0.5, 0.786) to visualize multiple retracement zones.
