What are Fibonacci retracement levels?

Fibonacci retracement levels are support and resistance levels that are calculated using several important points in a price series such as a high and a low. It is based on the famous Fibonacci sequence invented by the Italian mathematician Leonardo Pisano Bigollo. ^[1] A fibonacci number is an integer in an infinite mathematical sequence (1,1,2,3,5…) starting from the number 1 and then followed by the sum of the previous 2 integers.

How to use Fibonacci in Forex trading?

Fibonacci trading levels are often used as important support or resistance levels (or turning points) of a price. This is because numbers in the sequence are frequently found in nature, which many traders believe in their relevance in the financial markets as well.. In trading, the Fibonacci levels are represented by the following retracement levels: 23.6%, 38.2%, 61.8%, 78.6%, 161.8%, 261.8% (a 50% retracement levels and 100% are also often used although they are not official fibonacci levels).

For example a EURUSD price of 1.3200 can retrace by 23.6% to 1.0084 which can be used as a support to buy at. Consequently, these levels can be also used as a stop loss or take profit levels.

Since Fibonacci can be applied to any mathematical sequence, it can be used in many different formats with your trading, for example :

Fibonacci Extension (Retracements) - as the name suggests, horizontal extensions are drawn on a price chart using the Fibonacci level to predict the target price levels.

Fibonacci Fan - same as extensions, only the targets are plotted using trendlines, originating in the same price point.

Fibonacci Arcs - half circles extending from the center of the circle outwards, connecting a high and a low, called the base line.

Fibonacci Channel - a variation of the fibonacci extension where the channels are plotted diagonally.

Fibonacci Expansion - expansions of the price, the opposite of retracement.

Fibonacci Time Zones - Fibonacci levels that are applied to time and predict levels based on time/date rather than price.
