Level-Up Your Retail Trading with Depth Data
Active retail investors in the U.S. equities market are demanding access to more granular information. Bring your investing decisions to the next level with depth-of-book data.
Market Data Empowers Investment Decisions
When much of the world entered lockdown at the onset of the COVID-19 pandemic, an unexpected phenomenon began to take shape on Wall Street. The “rise of retail” was a moniker that emerged during this period to describe the unprecedented entrance of new retail participants into the stock market.
Whether you're new to investing, or you've been trading for years, one truth remains consistent: the depth of your insights often determines the depth of your success. To effectively trade, now more than ever, you need access to depth data.
Understanding Depth-of-Book
To understand depth data, you have to first understand top-of-book data, also known as Level I data. This data provides basic price information about a security.
Once you have an understanding of Level 1, you can start to look at depth-of-book data. Sometimes called Level II data, depth-of-book refers to the full robustness of an order book. It's a comprehensive view of all trading activity, providing every quote on the book so that you can get insight into the true supply and demand for a particular security.
Level I
A top-level view of the market with last sale pricing information, trade volume, and the latest bid and ask quotes.
Full Depth-of-Book
A full look at the current order book with outstanding buy and sell orders and the number of shares at each price level.
Depth Data: The Big Picture
The granular details from full depth-of-book create more nuanced and competitive trading, allowing you to:
Follow pockets of liquidity over time
Depth-of-book showcases orders at all price levels. Observing these can help you identify shifts in demand and supply, signaling potential market sentiment.
Understand order distribution
Pinpoint key support and resistance levels, which represent the price levels at which the direction of a stock or market tends to stop and reverse.
Identify new trading opportunities
See where many orders are placed or where few exist so that you can recognize opportunities to buy or sell.
Forecast market patterns
Determine potential trends and shifts before they fully materialize.
