The BMLL Trades dataset contains a trade-by-trade view of the market, across multiple execution venues and trading mechanisms (including on and off exchange, lit and dark liquidity sources e.g. OTC, SIs and Dark). By incorporating trade amendments, high-granularity timestamps, and consistent trade condition codes, the BMLL Trades dataset provides the most detailed view of historical trading activity available.

Product Overview:

  • A normalised view of trade information across all major European equity venues.
  • MMT flags (where available) and exchange trade condition codes included.

  • Nanosecond or microsecond precision timestamps, based on order-matching engines.

  • Time of trade and publication are included for delayed trade reporting.

  • Amended or cancelled trades included.

  • Aggressor side identified for lit trading using BMLL Level 3 order book data.

Use Cases:

  • Buy-side - backtest strategies, perform TCA and execution analysis, and generate alpha.

  • Sell-side - backtest execution algorithms, improve smart order routers and demonstrate best execution, track liquidity fragmentation and remain informed of changes to market structure.
