This table displays the latest balances for each currency in your portfolio, and the value of those balances in a particular currency. This includes all currencies that have a non-zero balance in your portfolio – not just your reporting currencies.
For each account, address and offset in your portfolio, the balances, history and transactions are summed up for each currency into a balance for that currency. The value of that balance is then calculated for right now, and for one week ago. This weekly change of the value is also included.
If you are looking for a table that just displays the balances without any conversions, consider the Portfolio Balances chart. If you are looking for a table that displays the value of your entire portfolio for all of your reporting currencies, consider the Portfolio Converted Value table.
