Volatility (Both implied and historic) and Stock Price Are displayed in the main charting area

Return, Option Volume, Open Interest, and Stock Volume data are displayed only for the Primary Security  if more than one security is being charted. The Primary Security  may be changed either by clicking on the security name in the Legend, or by clicking the security’s tab in the Data Grid at the bottom of the VolEdge window (if visible).

Daily Return

Return data is displayed in a strip directly below the main charting area. Positive observations are displayed in green and negative observations in red. Outliers (if visible) are highlighted and explicitly labeled with the observation’s value. The Return Axis is capable of either scaling it’s range to fit the available data, or being “pinned” to a specific range, while highlighting outliers. To control the behavior of the Return Axis, use View -> Return Axis Range in the VolEdge main menu.

Skew

Volatility surface data (Skew and Kurtosis) are displayed in the Skew Axis.

Option Volume, Open Interest, and Stock Volume are all displayed in an area directly below the Return/Skew detail area, or below the main charting area if neither the Return nor Skew are visible. Option Volume and Open Interest share the axis on the left, Stock Volume is displayed using the axis is on the right. While only the Primary Security’s data for these metrics are displayed, the ranges for these axes are set using the overall maximum of all active securities. This is done so that the axis ranges remain constant while switching the Primary Security. The low end of these axes ranges are fixed at zero, while the high end is determined by the data being charted.

Option Volume

The call and put observations for each day are drawn as a single line, such that the overall height of the line indicates the total option volume, call being stacked atop put.

Open Interest

The call and put observations for each day are drawn as a single line, such that the overall height of the line indicates the total option volume, call being stacked atop put.
