Getting Started with LSEG Data

To begin understanding data from Reuters, it’s helpful to break it up into different groups. The easiest way is to start with these four:

  1. Country-level: data that belongs to different countries.
  2. Asset classes: equities, fixed income, etc.
  3. Market-level: data that belongs to different exchanges or other recognised markets.
  4. Real-time and historical data.

The first three types are self-explanatory, but it’s worth looking at the fourth to understand the difference between real-time and historical data. Why? Because before you start using Reuters data, you need to tell Reuters which real-time exchange data you need.

WHAT DO WE MEAN BY REAL-TIME DATA?

Real time means almost immediately. When a trade is made at an exchange or a new rate is set, then you see it almost as soon as it happens – sometimes within a fraction of a second, regardless of your location. This real-time data can come from exchanges, from registered contributors on the Reuters network or from third-party data providers.

EXCHANGE-TRADED REAL-TIME DATA

All Reuters services supply the general financial information and news you have subscribed to. However, exchanges reserve the right to charge a small additional fee for the delivery of real-time data to your terminal. If you want to know more about charges for particular exchanges, your local Reuters representative will be able to tell you the exact fees for the data you require.

If you only usually need indicative prices, most exchanges also provide delayed data, which is free of charge. For more information on this, please refer to the Delayed data chapter in this guide.
