Probability Calculator

Try this tool

Our Probability Calculator can help you estimate your probability of success for any options strategy. Just pick your underlying security and select up to two target prices. You can adjust variables like volatility, interest rates, dividends and more. The Probability Calculator shows you the statistical odds of your trade either touching your targets or finishing below, between, or above them. You'll also see the prices representing one, two and three standard deviations for the underlying security.

The flexible, intuitive interface makes the Probability Calculator suitable for both novice and advanced users. You'll want to use it before every trade you make.
