The order book consists of buying and selling orders, where the buyers reflect the bids and the sellers the ask. The crucial thing is that a trade only gets executed when the buy and sell order match at the same price. Conversely, a bid-ask spread may be high to unknown, or unpopular securities on a given day.
It is also a measure of market liquidity, showing how much buyers and sellers are willing to trade at different prices. A wide bid-ask spread may indicate that there are not many buyers and sellers in the market or that they are not willing to trade at the current prices. Trading volume refers to the number of shares that exchange hands during a given period, measuring the liquidity of a stock. Many investors look to buy or sell shares of these companies at any given time, making it easier to locate a counterparty for the best bid or ask price.
Difference between Bid and Ask Size
The seller defines his price for what he is willing to sell his shares for. The difference between the bid and ask price is called the spread. Bid-ask spreads can be as small as a few cents or larger https://www.bigshotrading.info/ than 50 cents or $1, depending on the security that’s being traded. The market sets bid and ask prices through the placement of buy and sell orders placed by investors, and/or market-makers.
The highest proposed purchase price is the bid and represents the demand side of the market for a given stock. If you are a buyer, you want to buy a specific stock for either a specific price limit or want to get the stock for the best possible price. If you are using a limit order, you make a bid with your limit price to buy shares for that price and the number of shares defined in your order. The order book collects the offers from buyers who want to buy for a specific price and visualizes those bids on the bid side. As with bid and ask prices, the spread between bid and ask yields is wider when markets are illiquid and narrower when there is a lot of trading activity. This spread would close if a potential buyer offered to purchase the stock at a higher price or if a potential seller offered to sell the stock at a lower price.
When to Focus on the Bid and Ask Prices
The bid can be said to represent the demand for an asset, and the ask represents the supply, so when these two prices move apart, the price action reflects a change in supply and demand. A security’s price is the market’s perception of its value at any given point in time and is unique. To understand why there is a “bid” and an “ask,” one must factor in the two major players in any market transaction, namely the price taker (trader) and the market maker (counterparty). If the current stock is offered at $10.05, a trader might place a limit order to also sell at $10.05 or anywhere above that number.

- They have a duty to ensure efficient functioning markets by providing liquidity.
- When you cruise gas stations looking for a better price, you’re combing through the ask prices because you probably have a “bid” price in mind you want to pay.
Typically, an asset with a narrow bid-ask spread will have high demand. By contrast, assets with a wide bid-ask spread may have a low volume of demand, therefore influencing bid vs ask wider discrepancies in its price. If all market makers do this on a given security, then the quoted bid-ask spread will reflect a larger than usual size.
