If you’re looking to maximize your trading strategy, knowing how to use Fibonacci extensions on Thinkorswim can be very rewarding. Traders who know Fibonacci extensions have the ability to identify potential price targets beyond the standard Fibonacci retracements, making them a crucial tool for technical analysis.

In this guide, you will learn how to effectively use Fibonacci extensions on Thinkorswim, including how to set them up, interpret them, and apply them in your trading decisions. The aim is to ensure that you have a well-rounded understanding of the topic.

What Are Fibonacci Extensions?

Fibonacci extensions are price levels that traders use to predict where an asset’s price might move following a retracement or pullback. These levels go beyond the traditional retracement levels and provide targets where the price may continue its trend. 

The most commonly used Fibonacci extension levels are 127.2%, 161.8% (Golden Ratio), 200%, 261.8% and 423.6%. These levels are derived from the Fibonacci sequence and are widely respected by traders due to their frequent occurrence in market trends.

  1. Click on the Drawings menu at the top of your chart.
  2. Choose Drawing Tools and select Fibonacci Extensions (also called Fibonacci Projections in some versions).

3.  Identify Key Swing Points

To correctly apply Fibonacci extensions, you need to:

  • Identify a major low (starting point of the move)
  • Identify a major high (peak of the move)
  • Identify the retracement point (the point where the price pulls back before continuing in the original trend direction)

4. Draw the Fibonacci Extension Levels

  1. Click on the swing low and drag the tool to the swing high.
  2. Extend it down to the retracement level where the price has pulled back.

How to Interpret Fibonacci Extensions in Thinkorswim

There are various ways to use Fibonacci Extensions in Thinkorswim platform. They are:

1. Using Fibonacci Extensions for Take Profit Targets

Once the price breaks past the previous high or low, Fibonacci extension levels act as potential targets. For instance:

  • If the price moves past the 100% level, traders often set their take profit at 127.2% or 161.8%.
  • If the price extends beyond 161.8%, the next targets are 200% and 261.8%.

2. Using Fibonacci Extensions for Stop-Loss Placement

You can also use Fibonacci extensions to set stop-loss levels:

  • If you enter a trade near the 100% level, consider setting a stop-loss below the retracement level.
  • If the price reverses before reaching an extension target, consider exiting the trade.

3. Confirming Fibonacci Extensions with Other Indicators

For better accuracy, use Fibonacci extensions alongside:

  • Moving Averages to identify trend direction.
  • RSI (Relative Strength Index) to detect overbought or oversold conditions.
  • Volume Analysis to confirm breakouts.

Applying Fibonacci Extensions in a Trade

1. A very good Example of Applying Fib Extensions is in Bullish Fibonacci Extension Setup

Imagine you’re trading Apple (AAPL) on Thinkorswim, and you notice the following price action:

  • Swing low at $150
  • Swing high at $170
  • Retracement back to $160

Using Fibonacci extensions:

  • 127.2% extension = $180 (First target)
  • 161.8% extension = $190 (Second target)

If Apple breaks above $170, these levels serve as potential take profit points.

2. Another Example is found in Bearish Fibonacci Extension Setup

For a bearish trade, let’s say:

  • Swing high at $200
  • Swing low at $180
  • Retracement back to $190

Using Fibonacci extensions:

  • 127.2% extension = $170 (First target)
  • 161.8% extension = $160 (Second target)

This means that if the stock price breaks below $180, it could reach the extension levels.
