Probability Calculator Demo
The Probability Calculator allows you the choice of using the implied volatilities of options or historical volatilities of securities to assess your strategy's chances of success before you place your trade. It factors in dividends and interest rates over any time period you input and returns the statistical probability the underlying will finishing above, below or between two target prices of your choosing.
The Probability Calculator can be useful for both stock and options traders alike.
