About US Equity Coarse Universe
The US Equity Coarse Universe dataset by QuantConnect is a daily universe of all trading stocks in the US for a given day with the end of day price and volume. The data covers 30,000 US Equities in total, with approximately 8,000 Equities per day. The data starts in January 1998 and is delivered each trading day. This dataset is created by taking the closing auction price tick from the daily L1 trade and quote exchange dumps.
This dataset depends on the US Equities by AlgoSeek dataset because universe selection adds and removes market data subscriptions and on the US Equity Security Master dataset because the US Equity Security Master dataset contains information on splits, dividends, and symbol changes.
QuantConnect/LEAN combines the data of this dataset with MorningStar Fundamental data in runtime. You can use this dataset in local development without the Morningstar counterpart.

Example Applications
The US Equity Coarse Universe dataset enables you to accurately design a universe of US Equities. Examples include the following strategies:
- Selecting securities with the largest dollar volume
- Selecting securities within a specific price range
- Selecting securities that have fundamental data available (together with MorningStar Fundamental data in Fundamental objects)
