Level 2

What Is Level 2?

Level 2 is a trading service provided by the Nasdaq stock market that offers real-time access to the Nasdaq order book. The order book includes the bid and ask prices for securities listed on the exchange, along with the size of these orders, and the market makers handling them.

Level 2 serves as an essential tool for day traders and market makers as it offers an in-depth view of market activity. It provides transparency into supply and demand for securities, helping traders make informed decisions.

Furthermore, it enables traders to identify potential trading strategies and assess market depth.

Understanding the Level 2 Interface

Bid and Ask Prices

The Nasdaq Level 2 interface displays bid and ask prices in real-time. Bid prices represent the highest price that buyers are willing to pay for a security, while ask prices are the lowest price at which sellers are willing to sell.

The difference between these two prices is known as the bid-ask spread.

Market Makers and Their Roles

Market makers are firms or individuals that stand ready to buy and sell securities at publicly quoted prices to ensure that trading continues smoothly.

On the Nasdaq Level 2 interface, each bid and ask price is accompanied by a market maker identification code, indicating which market maker is making that bid or offer.

Interpreting the Bid-Ask Spread

The bid-ask spread is a key aspect of market liquidity. A narrow spread indicates a highly liquid market, while a wide spread suggests lower liquidity. High liquidity often results in more efficient trading, as orders can be executed quickly and at desired prices.

Understanding the Size and Depth of Market

The size of an order indicates the total number of shares a buyer wants to purchase or a seller wishes to sell at a specific price.

The depth of market, shown on Level 2, reveals the number of open buy and sell orders at various price levels, giving traders insights into market demand and supply.

Overwhelming Amount of Information

Level 2 data provides a vast amount of real-time information, including multiple bid and ask prices, order sizes, and trading activity.

Processing and analyzing this data can be overwhelming, and traders may find it challenging to filter out the relevant information and focus on what matters most to their trading strategies.

Cost and Accessibility

Access to Nasdaq Level 2 data typically comes at a cost. Traders may need to subscribe to a data provider or brokerage that offers Level 2 data, which can add to their trading expenses. Additionally, not all brokers provide Level 2 data to their clients, limiting its accessibility for some traders.
