In Portfolio 2.0, the realized profit with shares in GBp-currency has faulthy calculations: When a portfolio in euros contains shares that are traded in GBp, it displays 5-figure percentages of gains or losses on transactions. With stocks traded in USD or other cuurency (like NOK), this problem doesn't occur.

For £ based portfolios buying Eur or US$ instruments, the unrealised gain in £ will never be accurate. This is because the actual book cost paid in £ cannot be entered into the transaction. This is also why Portfolio 2 will never be a true "cash management" system because there is no method for defining whether settlement should occur from £, $, Euro or Yen cash holdings.
