Understanding market depth
Imagine you're at a fruit market, and you want to buy some apples. You glance at the stall and see baskets of apples lined up at different prices. The number of baskets available at each price level gives you an idea of the market depth for apples.
How does market depth work?
1. Bid and ask orders
In the financial market, buyers place bid orders, indicating the maximum price they are willing to pay for an asset. Sellers, on the other hand, place ask orders, stating the minimum price at which they are willing to sell. Market depth shows the accumulation of these orders at various price levels.
2. Order book
The order book, often displayed as a market depth chart, illustrates the bid and ask prices along with the corresponding quantities. The chart allows you to see the depth of the market and how much buying and selling interest exists at different prices.
3. Liquidity and price movements
Market depth provides insights into the liquidity of an asset and can influence price movements. A high level of market depth indicates a liquid market with many participants, making it easier to buy or sell at desired prices. Conversely, low market depth can lead to price slippage and higher volatility.
Market depth in the real world
Let's say you're interested in buying shares of XYZ Company. You look at the market depth for XYZ shares and see the following:
Bid Price (Buyers):
- 100 shares at £10.50
- 200 shares at £10.45
- 300 shares at £10.40
Ask Price (Sellers):
- 150 shares at £10.55
- 100 shares at £10.60
- 250 shares at £10.65
Based on this market depth, you can observe that there is more buying interest at lower prices (£10.50, £10.45, £10.40) and more selling interest at higher prices (£10.55, £10.60, £10.65). This information can help you assess the supply and demand dynamics and make more informed decisions about when and at what price to buy or sell XYZ shares.
