About Short Strangle
A short strangle position consists of a short call and short put where both options have identical expirations and different strike prices. When selling a strangle short, risk is unlimited. Profit potential is limited to the net credit received (premium received for selling both strikes). The strategy succeeds if the underlying price is trading between the lower price strike (minus net credit) and the higher price strike (plus net credit).
About Long Strangle

About Short Straddle
A short straddle position consists of a short call and short put where both options have the same expiration and identical strike prices. When selling a straddle, risk is unlimited. Max Profit is limited to the net credit received (premium received for selling both strikes).

Options information is delayed a minimum of 15 minutes, and is updated at least once every 15-minutes through-out the day. The screener displays probability calculations based on the delayed stock price at the time the strategy is updated. The new day’s options data will start populating the screener at approximately 9:05a CT.
Fields displayed on the Straddle and Strangle strategies include:
- price – the delayed stock price at the time the strategy is updated for the underlying equity.
- Leg 1 (Call) Strike – the price at which the underlying security can be bought if the option is exercised.
- Leg 1 (Call) Delta – measures the sensitivity of the Leg 1 option’s theoretical value to a change in the price of the underlying asset.
- Leg 2 (Put) Strike – the price at which the underlying security can be bought if the option is exercised.
- Leg 2 (Put) Delta – measures the sensitivity of the Leg 2 option’s theoretical value to a change in the price of the underlying asset.
- Net Credit/Debit – the maximum profit on the spread
- % of Stock – the percentage of the premium in relation to the underlying price of the stock
- Avg IV – the average implied volatility of the calls and puts immediately above and below the underlying price.
- -BE – the lower limit necessary for the strategy to break even (Leg2 Strike minus Net credit/debit)
- +BE – the upper limit necessary for the strategy to break even (Leg1 Strike plus Net credit/debit)
- Probability – the probability the last price will be at or beyond the break even point at expiration.
We take the underlying stock price, the break even point (target price), the days to expiration, and the 52-week historical volatility, and then use those figures in this formula. Depending on the strategy, we use the above or below probability (i.e., the probability the price crosses the break even point).
Pabove = N(d)
Pbelow = 1 – N(d)
N(d)= x if d > 0
= (1-x) if d < 0
d = 1n(b/l) / v√t,
y = 1/(1 + 0.2316419|d|),
z = 0.3989423e – (d*d)/2,
x = 1 – z(1.330274y⁵ – 1.821256y⁴ + 1.781478y³ – 0.356538y² + 0.3193815y)
b = break even point
l = last price
v = 52-week historical volatility
t = days to expiration
e = 2.71828
For pages showing Intraday views, we use the current session’s data with new price data appear on the page as indicated by a “flash”. Stocks: 15 minute delay (Cboe BZX data for U.S. equities is real-time), ET. Volume reflects consolidated markets. Futures and Forex: 10 or 15 minute delay, CT.
The list of symbols included on the page is updated every 10 minutes throughout the trading day. However, new stocks are not automatically added to or re-ranked on the page until the site performs its 10-minute update.
Pages are initially sorted in a specific order (depending on the data presented). You can re-sort the page by clicking on any of the column headings in the table.
Most data tables can be analyzed using “Views.” A View simply presents the symbols on the page with a different set of columns. Site members can also display the page using Custom Views. (Simply create a free account, log in, then create and save Custom Views to be used on any data table.)
Each View has a “Links” column on the far right to access a symbol’s Quote Overview, Chart, Options Quotes (when available), Barchart Opinion, and Technical Analysis page. Standard Views found throughout the site include:
- Main View: Symbol, Name, Last price, Change, Percent Change, High, Low, Volume, and Time of Last Trade.
- Technical View: Symbol, Name, Last price, Today’s Opinion, 20-Day Relative Strength, 20-Day Historic Volatility, 20-Day Average Volume, 52-Week High and 52-Week Low.

Data Table Expand
Unique to Barchart.com, data tables contain an “expand” option. Click the “+” icon in the first column (on the left) to “expand” the table for the selected symbol. Scroll through widgets of the different content available for the symbol. Click on any of the widgets to go to the full page.
Horizontal Scroll on Wide Tables
Especially when using a custom view, you may find that the number of columns chosen exceeds the available space to show all the data. In this case, the table must be horizontally scrolled (left to right) to view all of the information. To do this, you can either scroll to the bottom of the table and use the table’s scrollbar, or you can scroll the table using your browser’s built-in scroll:
- Left-click with your mouse anywhere on the table.
- Use your keyboard’s left and right arrows to scroll the table.
- Repeat this anywhere as you move through the table to enable horizontal scrolling.
Also unique to Barchart, FlipCharts allow you to scroll through all the symbols on the table in a chart view. While viewing FlipCharts, you can apply a custom Chart Template, further customizing the way you can analyze the symbols. FlipCharts are a free tool available to Site Members.
Download is a free tool available to Site Members. This tool will download a .csv file for the View being displayed. For dynamically-generated tables (such as a Stock or ETF Screener) where you see more than 1000 rows of data, the download will be limited to only the first 1000 records on the table. For other static pages (such as the Russell 3000 Components list) all rows will be downloaded.
Free members are limited to 5 downloads per day, while Barchart Premier Members may download up to 100 .csv files per day.
Note: Due to licensing restrictions, Canadian fundamental data cannot be downloaded from Barchart.com. You will see “N/L” in a downloaded column when this is the case.
Should you require more than 100 downloads per day, please contact Barchart Sales at 866-333-7587 or email [email protected] for more information or additional options about historical market data.
