1. What is the Fibonacci Speed Resistance Fan?
The Fibonacci Speed Resistance Fan is a technical analysis tool that uses Fibonacci ratios to forecast price movements. It consists of a series of diagonal lines originating from a key price point, representing potential areas of support and resistance. Traders use it to identify trend retracements and continuation points.
“Speed resistance lines” are an analytical tool in technical analysis that is used for determining potential areas of support and resistance. Developed by Edson Gould, a prominent market technician who was famous for his market calls in the 60s and 70s, this tool is based on Fibonacci retracement points (38.2%, 50.0%, 61.8%, etc.). Speed resistance lines, consisting of three or more trend lines, are created by drawing the first trend line from the most recent low to the most recent high when the price action is in an uptrend, and from the most recent high to the most recent low when it is in a downtrend. The additional trendlines are drawn based on the Fibonacci ratios on both sides of the first line from the original point.
2. How Does the Fibonacci Speed Resistance Fan Work?
This tool works by drawing trend lines from a significant high or low, angled according to Fibonacci ratios (38.2%, 50%, and 61.8%). As price moves, these lines act as potential resistance or support zones. If the price respects these levels, it confirms their validity for future trades.
In practice, let’s take the EUR/USD daily price action for example, which can be in an uptrend or a downtrend:
1. In an Uptrend
Speed resistance lines mark three potential support levels to watch, indicated by the orange circles. A breakout below the middle line targets a move towards the first support level (0.618), and then it rallies after touching it. A break below the lower line (0.382) indicates enough weakness to consider a trend reversal. Once broken, the line extensions can then mark resistance, just as ordinary trend lines, as shown by the blue circles below.
2. In a Downtrend
Speed resistance lines mark a few support and resistance levels, depicted by orange and blue respectively. The role of the lines is the same as they do in an uptrend. A break above the upper line indicates a trend reversal. Once broken, these speedlines can then become support on a pullback.

3. How to Draw a Fibonacci Speed Resistance Fan
- Identify a major high or low in the price chart.
- Select the Fibonacci Speed Resistance Fan tool in your trading platform.
- Place the anchor point at the significant high/low.
- The tool automatically plots the Fibonacci-based diagonal lines.
- Observe how price interacts with these lines to determine potential support/resistance areas.
4. Key Fibonacci Ratios in Speed Resistance Fans
The primary Fibonacci levels used in this tool are:
- 38.2% – Represents minor retracements and trend continuation zones.
- 50% – A psychological level where price often reacts.
- 61.8% – The golden ratio, indicating strong support or resistance.

5. How to Use the Fibonacci Speed Resistance Fan in Trading
Traders can use this tool to:
- Identify key entry and exit points.
- Set stop-loss and take-profit levels based on resistance/support.
- Confirm trends when price respects these diagonal levels.
- Combine it with other indicators like RSI, MACD, or moving averages for stronger signals.
6. Fibonacci Speed Resistance Fan vs. Fibonacci Retracement
- Fibonacci Retracement: Draws horizontal support/resistance lines based on Fibonacci levels.
- Fibonacci Speed Resistance Fan: Projects diagonal lines to identify trend continuation or reversal.
- Best Use Case: Fibonacci Retracement is best for horizontal levels, while the fan is ideal for trend-based diagonal support/resistance.
7. Common Mistakes When Using the Fibonacci Speed Resistance Fan
- Misplacing the anchor point: Selecting an insignificant high/low can lead to inaccurate levels.
- Over-reliance: This tool should be used alongside other indicators, not in isolation.
- Ignoring market context: Strong fundamentals or news can override Fibonacci-based predictions.
8. Practical Examples of Fibonacci Speed Resistance Fan in Forex and Stocks
Example 1: EUR/USD Trend Analysis
- Price moves up, retraces to the 50% speed fan level, and resumes the uptrend.
- Traders buy at this level with stop-loss below the 61.8% fan line.
Example 2: Stock Market Breakout
- A stock retraces to the 38.2% speed fan line, confirming strong support.
- A breakout above this level signals a buying opportunity.
