Olive Account Value is the sum of Olive Buying Power and Maturity Value of active outcomes. It represents the total value of the account if all active outcomes are held to maturity and the underlier prices remain at the current level.
Olive Account Value is different from TD Ameritrade Account Value because TD's figure uses Current Value not Maturity Value of the outcome. TD Ameritrade Account Value represents the total value of the account of all active outcomes were to be liquidated immediately.
