About Fibonacci Retracements

Fibonacci retracement levels are horizontal lines that indicate possible support and resistance levels where price could potentially reverse direction. These levels are based on the Fibonacci sequence and are widely used by technical traders to identify potential reversal points in the market.

How to Use

  1. Enter the high and low price points of your selected price movement
  2. Select the market direction (uptrend or downtrend)
  3. Click "Calculate Levels" to generate the Fibonacci retracement and extension levels
  4. Use these levels to identify potential support and resistance areas for your trading strategy

What this calculates

Retracement and extension levels between a swing high and low.

Formula
retracement = high − (high − low) × ratio, for ratios 0.236, 0.382, 0.5, 0.618, 0.786
Worked example
A move from 1.0800 to 1.1000 is 200 pips. The 61.8% retracement sits at 1.1000 − (200 × 0.618) = 1.0876.
When to use it
To mark where a pullback might pause within a larger move.
Common mistake
The levels only exist because enough people watch them. They are reference points, not support — price passes straight through them regularly.
