LSEG Tick History:
One product, two datasets
With the rise of electronic and algorithmic trading, the demand for historical market data has been growing across all asset classes. The variety of use cases – from back testing and trade cost analysis, to risk management and algorithmic trading – means access to high-quality historical market data is essential.
LSEG’s Tick History solution has two, complementary datasets:

  • Tick History – providing normalised Tick History market data with information about changes in price. 
  • Tick History – PCAP – PCAP data that is timestamped to the nanosecond and contains all the electronic messages in a market, including every order, trade and modification. This is available in both raw and normalised formats. 
If Tick History is the magnifying glass, then Tick History – PCAP is the microscope – together they provide breadth as well as depth of data. Both sets of historical market data are necessary to gain comprehensive insight into today’s trading environment.
