Bid and Ask As with most trading in the financial markets, when you are trading a currency pair there is a bid price (buy) and an ask price (sell). Again, these are in relation to the base currency. When buying a currency pair (going long), the ask price refers to the amount of quoted currency that has to be paid in order to buy one unit of the base currency, or how much the market will sell one unit of the base currency for in relation to the quoted currency.
