Is it better to buy or sell on specific days of the week?
Trading currencies would be much easier if such conditions could be so easily predicted. However, there are periods when it is typically, though not always, disadvantageous to purchase or sell a given currency. Such periods occur when the market from which a particular currency originates is closed. As the currency’s primary traders, those in its nation of origin, are not active during this period, margins widen as those in other markets who hold the currency take advantage of reduced availability. Major currencies rarely experience this phenomenon as large amounts continue to be traded by other nations where markets are open.
