Fibonacci Time Zones   

Fibonacci Time Zones are a series of vertical lines. They are spaced at the Fibonacci intervals of 1, 2, 3, 5, 8, 13, 21, 34, etc. The interpretation of Fibonacci Time Zones involves looking for significant changes in price near the vertical lines. The first line is placed at an extreme point on the chart and the lines that follow are spaced at increasingly wider intervals in accord with Fibonacci sequence.
Usage:
The interpretation involves looking for significant changes in price at or near the vertical lines. It is most applicable to long-term analysis of price action and is probably of limited value when studying short-term charts.
