OptionSource Position Pane Update Settings

Position lines in an OptionSource Position Pane can be set to update in a variety of way. Each line can be updated in a different way allowing the most realistic valuation of an option position. The setting in the Update column determines how the ($)Value, ($)P/L, ImpVol, ($)Delta, Gamma, ($)Theta, ($)Vega, and Rho columns are updated and calculated.

There are two methods to change Update settings:
