Hunting for alpha, you need clues. We have over 100 trillion rows of them.
Markets are moving faster than ever – reflected by the exponential growth of market data volumes. This scale can strain a firm’s ability to record, store, and manage market data efficiently, making it harder to generate alpha, improve transaction cost analysis (TCA), deploy AI/ML models, run accurate backtests and more.
LSEG Tick History provides the depth, quality and global coverage needed to overcome these challenges. It delivers a complete, consistent view of decades of intraday trades, quotes and market‑depth data across hundreds of venues – enabling scalable, enterprise‑grade analytics.
Choose normalised, raw, parquet, delta, or CSV formats, and deploy on-prem, in the cloud with our shared storage models on AWS and GCP, or in hybrid environments – all without compromising performance, control, or data quality.
And for even greater precision, Tick History – PCAP provides high‑fidelity packet‑capture data with GPS ‑synchronised, nanosecond timestamps – ideal for advanced modelling and strategy refinement.

Instrument & Venue Access via Web/API
Access LSEG Tick History through a web interface or API, using either instrument‑based extracts or venue‑by‑day files. Choose the instruments, data fields, and time periods you need, with the option to schedule extracts to run automatically. For full‑venue coverage, download venue‑by‑day files containing every tick for all instruments traded on a specific venue on a specific day, and load them into your cloud or on‑premises systems.
Tick History – PCAP
LSEG Tick History – PCAP delivers global, cross‑asset PCAP data with GPS‑synchronised nanosecond timestamps sourced directly from exchanges, providing the high‑fidelity insight needed for modelling, strategy refinement, and end‑to‑end analysis. The dataset is available through multiple formats and delivery mechanisms, including Tick History Workbench — our analytic environment for data queries, exploration, and visualisation.
