Fibonacci Expansion

Fibonacci Expansion is a charting technique used to plot possible levels of support and resistance by tracking not only the primary trend but also the retracement.

The tool is very similar to the Fibonacci Retracement, but also it is intended to determine the end of the third wave. Unlike Fibonacci Retracement, this tool is built not on the only one trendline, but two.

While Fibonacci Retracement applies percentages to a pullback, Fibonacci Extensions apply percentages to a move in the trending direction. For example, a symbol's price goes from $5 to $10 and then goes back to $7.

The move from $10 to $7 is a Retracement. If the price starts rallying again and goes to $16, that is an expansion. In other words, Fibonacci Retracements count the pullbacks within one trend, while Fibonacci Expansion measures the impulse waves in the direction of the trend.

The tool can be used to establish profit targets or estimate how far a price may travel after a pullback ends. Expansion levels are also possible areas where the price may reverse.

Expansion is drawn on a chart, marking price levels of possible importance. These levels are based on Fibonacci ratios as well. When the first line is drawn, its height is considered as a unit interval later on.

The end of the second wave serves as a reference point for building an invisible vertical line. The corresponding lines are drawn from the reference point on the levels equal to 23,6%, 38,2%, 50%, 61.8, 100%, 161.8%, and 261,8%.

Usage¶

Fibonacci Expansion is usually applied where the other methods of finding support or resistance are not applicable. If the price moves through an expansion level, it may continue moving toward the next.

The price itself may not stop or reverse exactly at the level, but the area around it may be important.

If a long position is opened and a new high occurs, the Fibonacci Expansion can be used for knowing where the price may move. The same is applicable for short positions. Fibonacci Expansion can be calculated to give the ideas on profit target placement.

You can use Fibonacci Expansion for any timeframe or any market. Typically, clusters of Fibonacci levels indicate a price area that will be significant for the stock and the traders in their decisions. Since expansion levels can be drawn on different price waves over time, when multiple levels from these different waves converge at one price, that could be a very important area.

In cTrader you have a Fibonacci Expansion instrument in your toolbar that allows drawing the tool on the chart, moving it, and configuring depending on your needs. You can find a detailed description of how to use it in the Fibonacci tools section of this documentation.

Flaws¶

It is a common practice to use Fibonacci Expansion along with the other indicators or patterns when looking to determine price targets, as the tool is not supposed to be the only marker of whether to buy or sell.

Candlestick charts and price action are especially informative when trying to determine whether a stock is likely to reverse at the target price.

There is no guarantee that the price will grow or reverse at a specific Fibonacci Expansion level. And even if it does, it is not evident before a trade is made. The price may move through many of the levels or not even reach any of them.
