On the right is a profit graph of the position with the green line showing the profit at expiration and the blue line at 43 days prior to expiration. The blue line days can be set by entering a value in the Plot Days edit box. In the bottom section of the window is the analysis of the position. The probability of reaching specified profit targets prior to expiration is determined using Monte Carlo analysis. 


The window below shows the probability of ever exceeding the upside or downside breakeven price levels. Reliability of the calculation can be monitored using the model lognormal mean and model volatility. The mean should be close to zero and the model volatility close to the input volatility.

Unchecking this box results in a probability calculation applicable to futures. You can check out an option probability calculator on our partner site.
