A 'MarketPrice' represents a historical exchange rate between two
|
|
commodities. (Ledger calls them historical prices.) For example, prices
|
|
published by a stock exchange or the foreign exchange market. Some
|
|
commands (balance, currently) can use this information to show the market
|
|
value of things at a given date.
