OFFER/ASK PRICEThe price at which the market is prepared to sell a product. Prices are quoted two-way as Bid/Offer. The Offer price is also known as the Ask. The Ask represents the price at which a trader can buy the base currency, which is shown to the right in a currency pair. For example, in the quote USD/CHF 1.4527/32, the base currency is USD, and the ask price is 1.4532, meaning you can buy one US dollar for 1.4532 Swiss francs. In CFD trading, the Ask represents the price a trader can buy the product. For example, in the quote for UK OIL 111.13/111.16, the product quoted is UK OIL and the ask price is £111.16 for one unit of the underlying market.
