NASDAQ TotalView is a premier financial data feed that provides the most comprehensive view of the NASDAQ order book. It showcases every single quote and order at all price levels for NASDAQ-listed securities. This level of detail includes not only the top-of-book information such as the highest bid and lowest ask but also all the orders behind them, offering a full depth of market insight.

Unlike basic market data feeds, which may only provide the top level of bids and asks along with the last traded price, NASDAQ TotalView delivers a full-depth view of the order book. This includes detailed information about all visible and hidden orders, providing a much clearer picture of market liquidity and potential price movements. This can be particularly useful for sophisticated trading strategies that require a deep understanding of market dynamics.

NASDAQ TotalView is beneficial for a wide range of market participants, including individual investors, professional traders, and financial analysts. It is especially valuable for those involved in high-frequency trading, day trading, and algorithmic trading, as it offers the detailed market data necessary for making informed decisions. Additionally, anyone looking to gain a deeper insight into market trends and liquidity can benefit from TotalView.

No, NASDAQ TotalView data is not limited solely to US stocks. While it primarily focuses on providing detailed insights into the order book for NASDAQ-listed securities, which includes a vast array of US stocks, TotalView also offers visibility into certain international stocks that are traded on the NASDAQ exchange. This includes American Depositary Receipts (ADRs), which are shares of foreign companies available for trading on US exchanges. Therefore, investors interested in both domestic and select international market activities can benefit from the comprehensive data TotalView delivers, encompassing a broader spectrum of equities beyond just US-based companies.
