It can also be useful to compare how the projections change when they're based on different volatility figures. To base your probability calculation on a weighted moving average, choose from the "Implied Volatility" pulldown menu. You can view probabilities based on historical volatility HV , actual historical price patterns, or based on the iVolatility Index, a proprietary index model created by iVolatility, that calculates a weighted average implied volatility for specific time periods.
You can also compare time frames ranging from day to day weighted averages. The Probability Calculator also provides projected interest rate data and dividend information for the time period you choose. The interest rates used are the projected risk-free interest rate you'd earn over that time period.
If you believe interest rates will differ from what the Probability Calculator suggests, simply enter your own interest rate figure. Similarly, you can overwrite the dividend information if you anticipate changes on that front for the underlying.
