volatility screener Help

Expensive puts and expensive calls are option contracts that have high premiums.

The Volatility Screener offers numerous methods for screening expensive option contracts:


Stocks can be filtered by price and volume.

  • Price Range - set the sliders to the minimim and maximum prices. Only stocks with a price between the minimum and maximum prices will be included in the screen.
  • Stock Volume - Only stocks with a daily volume between the minimum and maximum volume will be included in the screen.
  • Implied Volatility - only show stock with an implied volatility in the selected range
*Tip: A slider can be moved by clicking anywhere on the slider bar.

Options can be filtered by Volume, Moneyness and Expiration

  • Option Volume - set the sliders to the minimum and maximum volume of all contracts. Only stocks with total option volume in the selcted range will be evaluated in the screen.
  • Moneyness - refers to the number of strikes an option is in or out of the money. Options with a moneyness of zero are At The Money (ATM). Strike prices increase as the moneyness becomes more positive. Strike prices decrease as the moneyness becomes more negative. For call spreads, a positive number is Out of The Money (OTM). Negative numbers are In The Money (ITM). For put spreads, a positive number is In The Money (ITM) and negative numbers are Out of The Money (OTM). See Moneyness.
  • Expiration - include only options that expire between the start of the earlier month and the end of the later month. Options expiring on any date in the selected months may be included in the screen, including weekly options, quarterly options, and options that expire on odd days (e.g. VIX options). Both expiration sliders may be set in the same month. All options expiring in the selected month will be considered in the screen.
*Tip: Click the chart button to show the spread in the Strategy Calculator.
  • Saving a Screen  - Subscribers can save screen parameters and recall these parameters later. Screener type, slider values, and sort order parameters are saved. The date of the screen is not saved. When a saved screen is opened, the parameters will be applied to the currently selected date.
  • Sort By - the order in which the screener results are displayed int Change in Volatility screen. The results may also be sorted by clicking on column headers. Sorting by clicking on column headers only sorts the data that is already in the report.
