AutoFibRetracement is a technical indicator overlay tool that automatically plots Fibonacci retracement levels on price charts. It detects recent swing highs and lows within a user-defined lookback window to calculate key Fibonacci levels—0%, 23.6%, 38.2%, 50%, 61.8%, 78.6%, and 100%—which are color-coded for clarity. The indicator offers customizable visual settings including line opacity, thickness, and style, allowing seamless integration with other chart elements. Designed for traders who use Fibonacci retracements to identify potential support and resistance zones, it supports various symbols such as BTCUSD, EURUSD, GBPUSD, XAUUSD, NAS100, and USDJPY. The effectiveness depends on selecting an appropriate period window to capture meaningful market swings. This tool is suitable for swing traders, trend followers, and technical analysts aiming to plan entries, exits, and stop-loss levels based on Fibonacci zones.
