Bid and Ask Price
You may be asking yourself what does Bid and Ask price mean, or why is the Bid and Ask price so different. Our detailed guide explains these differences and aims to improve your understanding.
The Meaning of Bid and Ask in Market Trading
The bid and ask price refers to the two way quote given on all exchanges and are normally the best potential prices to trade at. The market is made up of many different participants but at its simplest, the highest bid (a price at which you can sell) and the lowest offer (the price at which you can buy) determine the current bid and ask (or ‘offer’).
The difference between the bid and ask prices is commonly known as the Spread. It is normally a good sign of liquidity in that product if the spread is low (sometimes also referred to as ‘narrow’ or ‘tight’).
It is easy to get the bid and ask price confused due to the way they are named, but once you understand a few basic terms it should become clear.
The bid price is the highest price for which somebody (other market participants or market makers) is willing to bid you (to buy something). As a trader, you will look at the bid price when you SELL a product.
The ask price (also known as the offer) is the lowest price for which somebody is willing to sell something to you, hence it is the lowest price they ‘ask’ you to pay or ‘offer’ the product to you. So, as a trader, you will look at the ask price as the price you pay to BUY a product.
In addition to the bid and ask price, you will see the volumes of each bid and ask price available for most products. This shows how much quantity of the product is available at the price being shown. These are more commonly referred to as the “bid size” and “ask size”.
How is the Bid and Ask Price Determined?
The bid and ask prices are primarily determined by the forces of supply and demand in the market. If a particular asset’s demand surpasses its supply, the bid price tends to increase. Conversely, if supply exceeds demand, the bid price may decrease.
The ask price follows a similar pattern but in the opposite direction. As demand for an asset grows, sellers can command higher prices, leading to an increase in the ask price. On the other hand, when supply exceeds demand, sellers may need to decrease their ask price to attract buyers.
External Influences on Bid and Ask Prices
Various external factors can also influence the bid and ask prices of a security. These may include market news, economic indicators, changes in investor sentiment, and geopolitical events, among others. These factors can affect traders’ perceptions of a security’s value, leading to changes in bid and ask prices.
The Impact of Liquidity on Bid and Ask Prices
Liquidity can significantly impact the determination of bid and ask prices. In a highly liquid market, where there are many buyers and sellers, the bid-ask spread tends to be narrow. This is because competition among market participants often leads to bid and ask prices being close to each other. In contrast, in a low liquidity market, the bid-ask spread may widen due to a lack of competition.
The Role of Bid and Ask in Stock Markets
In the stock market, the bid and ask determines the price at which a stock can be bought or sold at any given moment. When you decide to buy a stock, you pay the ‘ask’ price. Conversely, if you wish to sell a stock, you’d receive the ‘bid’ price.
The bid-ask spread, defined as the difference between these two prices, is a key indicator of the stock’s liquidity. A smaller spread often implies a more liquid market, where buyers and sellers are in close agreement on price. Conversely, a wider spread may signal a less liquid market, which could involve more price risk for traders.
Bid and Ask in Bonds and Options
Bond and options markets also rely on the bid and ask system. In bond markets, these quotes represent the most favourable terms at which you can buy or sell a bond. Options markets, too, use bid and ask prices to indicate the rates at which an option contract can be bought or sold.
Market Makers and the Bid-Ask Spread
Market makers play a significant role in managing the bid-ask spread. As official intermediaries between buyers and sellers, they use their own inventory (book) to meet demand, thus helping to maintain liquidity and keep an active quote while following exchange rules. Market Makers will look to make a profit on the bid-offer spread.

These concepts drive the mechanics of buying and selling in financial markets, making them essential knowledge for any trader or investor. By comprehending how these prices interact, one can make more informed decisions and potentially increase the likelihood of profitable trades.
