The parameters for the Zig Zag are shown below. These parameters are specified at the time the indicator is plotted. You can edit the parameters of an existing plot by right-clicking on the indicator and choosing Properties from the shortcut menu.
Price Field. Choose the price field (i.e., open, high, low, or close) to use when calculating the Zig Zag.
