In financial markets, an inside quote is the best available bid and ask, or offer, price for a stock or other financial security. Inside quotes are established by collecting bids and offers from market-makers or professional traders working for exchange member firms who are responsible for actively making bids and offers in a particular stock and then sorting them according to highest bid and lowest ask prices, as well as transaction size or other secondary data. Using an exchange's trading system, electronic trading networks or networks of inter-dealer brokers post the best prices at which they are willing to buy — their bid prices — or sell — their ask or offer prices. The difference between them is known as the bid-ask spread. As market conditions change and order flows vary, they may raise their bids, or lower their offers, in order to fill a particular order or increase their chances of attracting a seller or buyer respectively. If this is better than the highest bid and lowest offer currently available on the market, a new inside quote is established.
