You can run simulations for the value of various risk parameters: delta, gamma, vega, theta. You can study changes to the strategy value as well as to various strategy risk parameters, e.g., you can see how the delta of a strategy will change if market prices drop and volatilities rise. Or how much theta value you can get per one day of holding your position as it approaches expiry. iOptioneer will give you an opportunity to get not only the information, but the "feel" of how different option strategies behave in the real world.
