Fibonacci Clusters is a tool used in technical analysis that combines different Fibonacci numbers, each of which is taken from different highs and lows. Fibonacci clusters are indicators that are usually plotted on the price chart and look like a series of horizontal bands with varying degrees of darkening. Each correction level that overlaps with another one makes the horizontal band on the side at this price level darker. The most significant support and resistance levels are those in which the Fibonacci cluster is displayed the darkest.

This is a useful tool for quickly assessing the relative strength of support or resistance of various price levels. Traders usually closely monitor the volumes concentrated near certain levels, which confirms the strength of this support/resistance level.
