Foreign exchange charts are available from major financial websites such as MSN Money and Yahoo Finance. Specialty Forex websites, such as DailyFX and FXStreet, also make charts available.
Foreign exchange rates are the rate at which one currency can be exchanged for another. These rates fluctuate over time based on the interest rates paid to hold that currency, either by debtors or depository institutions. Profits can be made if the change in exchange rate between two currencies can be predicted by an investor. Investors purchase one currency by converting their money into a foreign currency, then make profits by converting the foreign currency back into their native currency.
