Invested Capital is the value of the cash currently tied in an Investment. When the Investment is open (i.e. it is part of your portfolio), Invested Capital is the sum of all your Deposits minus all your Withdrawals into the Investment. When in the Investment is closed (i.e. you have sold it or written it off), Gross Invested Capital is displayed, and it is the sum of all the Deposits you had made into the Investment while it was open - in other words, the total capital you had invested in it.
