option screener Help

The Option Screener lists complex option trades that consist of two option legs. Both legs of Bull Calls, Bear Puts, Bull Puts, Bear Calls, Calendar, and Diagonal spreads are either puts or calls, and one leg is long while the other is short.

Straddles and Strangles consist of one call leg and one put leg, and both are long or both are short.

 The Option Screener offers numerous methods for screening option spreads:


Stocks can be filtered by price and volume.

  • Symbol - Optionally enter a stock symbol to limit the screen to spreads on the underlying stock.
  • 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.
*Tip: A slider can be moved by clicking anywhere on the slider bar.

Options can be filtered by Volume, Moneyness and Expiration

  • Leg Volume - set the sliders to the minimim and maximum volume of the long contract. If only one volume slider is available for an option it will apply to all the options in the spread.
  • 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: Subscribers can save reports.
  • Leg Volume - the minimim and maximum volume of the short contract.
  • Spread - the number of strikes away from the long leg. For example, a Bull Call on a stock with $95, $100, and $105 strikes that has a long leg of $100 and a spread of 1 will have $105 short leg. The $105 strike is 1 strike away from $100. To get a call spread with a $100 long leg and a $95 short leg, select Bear Calls.
*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, symbol, sort order, and "One Row Per underlying' 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.
  • One Row Per Underlying - Show only the first occurence of an option for underlying stock.  
  • Sort By - the order in which the screener results are displayed. Up to 100 rows are included in each screen. The results may be sorted by clicking on column headers. Sorting by clicking on column headers only sorts the data that is already in the report.

    • NetIVol - the difference in the volatility of the two legs weighted by the maximum profit.
    • Net Debit/Credit - the maximum profit, without regard to the volatility.
    • ROI - return on investment if a covered position is called. ROI is only available for the Expensive Calls screen and the Expensive Puts screen.

  • Fields for both the Short and Long Leg:

  • Credit or Debit - the net cost or net proceeds from the trade of the spread, i.e. the price of the short leg minus the price of the long leg
  • Spread - the difference between the strike prices
