Fibonacci retracement lines
Aug 10, 2019
The Fibonacci retracement lines indicator automatically identifies and plots key Fibonacci levels based on price action over a user-defined historical lookback period to help traders spot potential support and resistance zones.
Usage
The tool can be used to identify potential reversal points or areas where price might consolidate. When the tool detects a downward trend relative to the lookback period, it plots the levels accordingly; the same logic applies to upward trends. Traders can use these levels (0, 0.236, 0.382, 0.5, 0.618, 0.786, and 1) to set price targets or stop-loss orders. The indicator includes circle-style plots for each level and dynamic labels to show the specific Fibonacci ratio.
Details
The script calculates the highest high and lowest low over a specified number of bars. It then determines the trend direction by comparing the current close to the close at the start of the lookback period.
- In a bullish context, the levels are calculated from the bottom (lowest low) upwards.
- In a bearish context, the levels are inverted, measuring the retracement from the top (highest high) downwards. The primary ratios included are based on standard Fibonacci sequences used in technical analysis to find equilibrium and retracement targets.
Settings
- Calculate for last bars: Determines the lookback period (number of bars) used to find the highest high and lowest low for calculating the Fibonacci range.
