Choose either Fibonacci Time Cycles or Fixed Time Cycles. Fibonacci Time Cycles are also called Fibonacci Time Zones.

With Fibonacci Time Cycles, vertical lines will be drawn at increasing intervals. These intervals are based on the Fibonacci Numbers.

Fixed Time Cycles will be drawn at regular intervals. They are represented by semi-circles. Their size is specified in the edit box to the right of Fixed.

Because ChartOverlay cannot actually see the bars on the chart you are studying, you must give it the information needed to draw the time cycles accurately. This information has two key elements. One element is the horizontal line you will draw. This line will indicate two things: the starting point for the cycles and a length. The second element is the Calibration Length, which tells ChartOverlay haw many bar widths are represented by the length of your line. ChartOverlay will use this to calculate an average bar width. Stating the Calibration Length is similar to describing the length of a fence; whereas 10 sections of fence require 11 fence posts, a Calibration Length of 10 requires 11 bars. It is important that the line you draw begin and end at the same point in the first and last bar (eg, center to center or left edge to left edge). If the chart you are studying has a large number of closely-packed bars, you should increase the Calibration Length accordingly so that an accurate average can be determined.

You can select the Color of your Lines by clicking on the colored square to the left of Line Color. You can also change the Style used to draw the Lines to any of the defined values (Normal, Wide, Dashed, Dotted, Dash-Dot, Dash-Dot-Dot or Invisible) using the drop down list to the right of Line Style.
