Fidelity Trade+ (Windows) Miscalculates Total Basis
The "Total Basis" displayed in the Trader+ app (windows) double counts the basis for BrokerageLink investments by including the account itself as well as the BrokerageLink basis in the 401(k) account.
If you use the app and have a BrokerageLink account associated with a 401(k) (and perhaps other similar accounts), so not use the total Basis to calculate anything until its fixed.
