What are stock market data systems?

Stock market data systems provide market data from a stock exchange to a wide range of consumers including third-party financial data vendors, investment banks, hedge funds and private investors and traders. The data includes last, high and low trade prices, volume and details of the order book.

Where have you heard about stock market data systems?

Whenever you’re watching the market, whether on an app, on a computer at home, or via a live ticker on a cable TV business channel, the prices and volumes are provided by stock market data systems. The data is especially important if you are a day-trader sensitive to price levels.

What you need to know about stock market data systems.

Stock market data systems are critical to the modern global financial markets. The speed at which they report changing bid and offer levels and trade prices and volumes has become central to many new machine-driven trading strategies. As a private investor, the speed and accuracy you require from the systems depends on your strategy. If you buy and hold for the long-term, you may only check on the closing price of the securities in your portfolio on a daily basis. However, if you’re an active day-trader you’ll need fast and accurate live data from the exchange in order to trade effectively.
