Tick History

LSEG Tick History is a historical market data archive offering over 30 years of tick-by-tick data from 580+ global venues and contributors, with a total storage footprint exceeding 80 petabytes and over 100 trillion rows of data covering all asset classes. It is designed for quantitative analysts, algo traders, risk managers, and data scientists who need deep, clean, and consistent intraday data for backtesting, transaction cost analysis, AI/ML model training, and market microstructure research. The service provides both level 1 and level 2 data reaching back to January 1996, with options for normalised (standardised across venues) or raw formats, including Parquet, Delta, and CSV, and can be accessed on-premises, in the cloud via AWS S3 and Google BigQuery, or in hybrid environments. For ultra-precision use cases, Tick History – PCAP delivers GPS-synchronised, nanosecond-timestamped packet-capture data, enabling advanced modelling and strategy refinement with the highest fidelity available.

Key capabilities include a custom extract service that allows users to precisely select instruments, fields, and time periods, with scheduled report generation; a large array of trade qualifiers per venue to ensure query precision; and full alignment to LSEG’s unified symbology and data model, enabling seamless integration with other LSEG datasets such as reference data and machine-readable news. The data is cleaned, structured, and normalised to support fast, consistent analysis, and the cloud-native access model reduces the need for local data storage and management. Users can also access data via a web interface or API for instrument-based extracts or venue-by-day files. The service offers 24/7 global support from LSEG experts.

In the historical tick data market, LSEG Tick History competes directly with Refinitiv Tick History, which was historically a separate offering but is now under the same LSEG umbrella following the Refinitiv acquisition. While both products provide deep historical coverage, LSEG Tick History distinguishes itself with its 80+ petabyte scale, 100+ trillion rows, and dedicated PCAP offering for nanosecond-precision data. Other competitors include Bloomberg’s B-PIPE historical data and SIX Financial Information’s historical tick data, though LSEG’s breadth of venues (580+) and 30-year depth are among the largest in the industry.

The primary trade-offs are that pricing is not transparently published—users must contact sales for quotes, and costs likely include historical redistribution licences and derived data licence charges, which can be significant for large-scale usage. The data’s sheer volume (80+ petabytes) can be overwhelming for smaller firms without cloud infrastructure or data engineering resources. Additionally, while normalised data reduces venue-specific quirks, some traders may prefer raw formats for bespoke processing, and the cloud-native model may introduce latency for firms requiring ultra-low-latency local access. Finally, the product is enterprise-oriented, with no self-service tier for individual researchers or small teams.

Not publicly listed; requires contacting LSEG sales. Costs likely include historical redistribution licences and derived data licence charges per the 2025 pricing guidelines, with fees based on unique instrument counts and usage tiers.
