A quote typically consists of a bid and an ask (or offer).

The bid price is the highest amount someone is currently willing to pay for the security, and it indicates the price a seller receives when selling the stock.

The ask price is the lowest amount someone is currently willing to sell the security for, representing the price a buyer pays when purchasing the stock.

The size refers to the number of shares currently available at the bid and at the ask, expressed in round lots (units of 100 shares).

The bid price is always less than the ask price in a stock quote.

The spread is the difference between the bid and ask prices, indicating the cost of buying and selling the security.

For listed stocks, the bid is established by the highest buy limit in the order book maintained by the Designated Market Maker (DMM), while the ask is based on the lowest sell limit.

The inside quote refers to the highest available bid and the lowest available ask, representing the best prices at which a security can be bought or sold.

Acting as a broker means facilitating trades between buyers and sellers without holding inventory of the securities themselves.

A dealer acts as a market maker, buying and selling securities for their own account, thus holding inventory and providing liquidity to the market.

A market maker buys and sells securities for their own account, while a broker facilitates trades between buyers and sellers without holding inventory.

The typical size for a stock quote is expressed in round lots, which are units of 100 shares.

When a stock is quoted at a certain price, it indicates the current bid and ask prices, reflecting the highest price buyers are willing to pay and the lowest price sellers are willing to accept.

In the OTC market, quotes are generated by broker-dealers acting as market makers, with the bid being the highest bid from a market maker and the ask being the lowest ask from a market maker.

For stocks priced above $1.00**, the smallest change (increment) that a bid or ask can be adjusted is **$0.01 (one cent).

The Designated Market Maker (DMM) maintains an order book for listed stocks, which includes all open limit orders, helping to establish the bid and ask prices based on the highest buy limit and lowest sell limit.

A market order to buy means purchasing the stock at the current ask price, while a market order to sell means selling the stock at the current bid price.
