Probability Calculator



Our Probability Calculator can help you determine your probability of success for any strategy, before trading options. Just pick your underlying security and select up to two target prices. You can adjust variables like volatility, interest rate, dividends and more. The Probability Calculator will show you the probability of touching, finishing below, finishing between, or finishing above your targets. You'll also see the prices representing one, two and three standard deviation moves 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.
