Level 1 vs Level 2 Market Data

In the world of finance and trading, market data plays a vital role in making informed investment decisions. However, not all market data is created equal. There are two primary levels of market data: Level 1 and Level 2. In this article, we’ll explore the differences between Level 1 and Level 2 market data and their importance in the financial industry.

What is Level 1 Market Data?

Level 1 market data, also known as the inside quote, provides traders with real-time bid and ask prices for a particular security. This data is sourced directly from the exchanges and is made available to the public free of charge. Level 1 market data only provides information on the best bid and ask prices, along with the volume of shares available at those prices.

For example, let’s say that the current bid and ask prices for a particular stock are $50.00 and $50.10, respectively. Level 1 market data would show these two prices along with the volume of shares available at each price.

While Level 1 market data is useful in providing an overall snapshot of a security’s price and demand, it does not provide traders with a complete picture of the market. Traders who rely solely on Level 1 market data may miss out on crucial information that could impact their investment decisions.

What is Level 2 Market Data?

Level 2 market data is more comprehensive than Level 1 data, providing traders with a deeper view of the market. Level 2 data displays real-time quotes for all the bids and asks, as well as the volume of shares available at each price point. This allows traders to see the complete order book for a security and get a better understanding of the market’s supply and demand.

Level 2 data is typically available through a direct feed from an exchange or a market data vendor. This data is often used by professional traders and institutions to make informed trading decisions.

For example, let’s say that a trader is interested in buying 1,000 shares of a particular stock. With Level 2 data, the trader can see all the bids and asks for the stock and determine the best price to enter the market. The trader can also see the volume of shares available at each price point and determine the overall supply and demand for the stock.

Level 1 vs Level 2 Market Data

While Level 1 market data provides a general overview of the market, Level 2 data offers a more detailed view. Here are some of the key differences between Level 1 and Level 2 market data:

  • Depth of Information: Level 2 data provides traders with a more comprehensive view of the market, displaying all the bids and asks for a security. Level 1 data only shows the best bid and ask prices.
  • Real-time Information: Both Level 1 and Level 2 data are real-time, but Level 2 data is often considered to be more up-to-date as it provides a more detailed view of the market.
  • Access to Data: Level 1 data is available to the public free of charge, while Level 2 data is typically only available through a paid subscription or a direct feed from an exchange.
  • Cost: Level 1 data is free, while Level 2 data can be expensive, with costs varying depending on the vendor and the exchange.

Importance of Market Data in Trading

Market data is an essential component of trading, as it provides traders with the information they need to make informed investment decisions. Traders who rely solely on Level 1 data may miss out on critical information that could impact their investment decisions. By utilizing Level 2 market data, traders can gain a deeper understanding of the market’s supply and demand, which can help them make more informed investment decisions.

Conclusion

In summary, Level 1 and Level 2 market data provide traders with a view of the market’s pricing and demand for a particular security. While Level 1 data offers a general snapshot of the market, Level 2 data is more detailed and provides traders with real-time quotes for all the bids and asks, as well as the volume of shares available at each price point. Professional traders and institutions often rely on Level 2 data to make informed trading decisions. It is also worth mentioning level 3 market data which is the highest level of market data available.
