Volatility Charts - Parameters and Appearance

The Action menu contains controls for managing the number and configuration of charts on the Volatility Charts work page.

A View is created containing a number of charts of various different data parameters and display values. These parameters and values are set and saved as a particular View. New Views are added to the function bar's View Selector drop-down menu.

Each time a different View is selected from the View Selector drop-down menu, the charts defined in the view are plotted onto the work-page.

Once a view is displayed on the work-page, it can be altered in the Volatility Plots dialog box.

Configure Current View

Select the Configure View... command from the Action menu to open this dialog box:

From here you can choose the number of lines that appear on the Volatility Chart, the period and data used to calculate and select the period and volatility type used to calculate the Volatility average.

Note - The Default View settings in this box will also control the display of the Volatility Chart in the Instant Symbol Overview area of the Symbols to Search tabbed page of the Trade Scanner work page.

Hide / Show General

Tick the first box in each row to enable the calculation of a volatility based on the parameters defined in its row.

When this box is checked, the data details for the row will appear in the Volatility Table at the bottom of the Volatility Chart work-page.

If the Chart check-box at the end of each the row is also selected, the data will also be plotted on the chart.

Periods

Enter the number of periods by which the volatility calculation is to take place.

Volatility Type

For each of the ten possible plots, there are eight different types of data groups available for calculation.

Type

Description

Historical

 

 

 

The historical (or statistical) average price of the underlying asset is calculated on a daily basis. First the range of stock price movement within a set Period is determined and used to establish a mid-point. Mid-points for the other periods that can be calculated within the number of Trading Days are then determined and then all are averaged. Users can set the length of the Periods, and the number of Trading Days is set at 252.

IV Average

 

 

An average implied volatility of all of the options available for an underlying security is calculated on a daily basis. It does so by calculating the implied volatility of each option for that security, discarding those that are very deeply in- or out-of-the-money and adding a weighting to those that are at-the-money and closest to expiry.

IV 0 - 30 Days

 

This provides an average implied volatility only for those options expiring within the next 30 days.

The filters used in the IV Average are also employed.

IV 30 - 60 Days

 

Calculates an average implied volatility only for those options expiring 30 to 60 days from present.

The usual filters are also employed.

IV 60 - 90 Days

 

Calculates an average implied volatility only for those options expiring 60 to 90 days from present.

The usual filters are also employed.

IV Over 90 Days

 

Calculates an average implied volatility for options expiring greater than 90 days from present.

The usual filters are also employed.

IV Calls

 

Calculates an implied volatility all of Call options available for an underlying security and is calculated on a daily basis.

The usual filters are also employed.

IV Puts

 

Calculates an implied volatility all of Put options available for an underlying security and is calculated on a daily basis.

The usual filters are also employed.

Style / Color / Weighting

Select from the following line styles: Solid, Dashes, Dots and Points

Use the drop-down color picker to select a color for the line.

Select between five different weightings (thicknesses).

Hide / Show in Chart

When the General Hide/Show check box at the beginning of the row is checked, the data will be calculated and put into the Volatility Table.

By default it will also be included in the Volatility Chart and the Chart check-box will be selected.

To only display the data in the Volatility Table, un-check the Chart check-box and the display in the chart will be turned off. The check-box at the start of the row in the Volatility Table will also be un-checked.

View's Default settings

After making all the required changes, click the OK button. The settings will be applied to the current work-page and those settings will be the default settings for the current View.

Last View Applies to New Charts

After closing a Volatility Chart, the View that was last applied will be applied to the new chart the next time a Volatility Chart is opened.

Manual Changes do not Affect Default Settings

Individual Volatility charts can later be toggled on or off from the Volatilities Table's chart display check-boxes, but the next time the view was applied, the default settings would be reapplied. For more information on this control, refer to the Volatilities Tables topic.

When a new Volatility Chart is opened, its current View's defaults will apply.
