Auto Fibonacci Extension and Retracement with Visual Alerts

The Auto Fibonacci Extension and Retracement with Visual Alerts tool automatically identifies significant price swings and plots key Fibonacci levels to help traders find potential support, resistance, and breakout zones.

Usage

This indicator serves as a dynamic framework for technical analysis by automatically adjusting Fibonacci levels based on recent market volatility. Traders can use the plotted levels in several ways:

• Identifying Support & Resistance: Retracement levels (displayed as blue dashed lines) can highlight areas where a trending price might pull back before continuing.
• Targeting Breakouts: Extension levels (displayed as green dashed lines) assist in projecting potential price targets or areas of trend exhaustion.
• Visual Interaction: The script places labels with arrows when the price interacts with extension levels, providing immediate visual feedback on price action relative to Fibonacci zones.
• Trend Confirmation: Users can combine these automated levels with other indicators or candlestick patterns to confirm entry or exit points.

Details

The script functions by scanning a user-defined lookback period to determine the highest high and lowest low (Swing High and Swing Low). Once these anchor points are established, it calculates two sets of lines:

1. Retracement Lines: Calculated between the swing high and swing low to identify internal price ratios.
2. Extension Lines: Calculated by projecting the swing range above the swing high to identify external price targets.

The tool updates these levels dynamically as new data enters the lookback window, ensuring that the Fibonacci analysis remains relevant to current market conditions.

Settings

• Lookback Period: Defines the number of bars the script scans to identify the current swing high and swing low.
• Fibonacci Levels: A space-separated list of decimal values (e.g., "0 0.382 0.618 1") used to calculate and plot the corresponding Fibonacci lines.

FAQ

How do I access Auto Fibonacci Extension and Retracement with Visual Alerts?

You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.

Can this indicator be used for automated trading signals?

While the script provides "BUY" and "SELL" visual cues based on specific Fibonacci level interactions, it is intended as a decision-support tool. It is recommended to use it alongside other technical analysis methods rather than as a standalone signal generator.

Why do the levels move over time?

The levels are dynamic and rely on the highest and lowest prices within the specified lookback period. If a new high or low is formed within that window, the Fibonacci grid will recalibrate to the new swing range.
