# Venues and Datasets

**Supported Trading Venues**

We execute across a range of venues, each offering different liquidity characteristics:

* **CLOB (Central Limit Order Book)** – Standard exchange-style order book where participants submit limit and market orders.
* **MATCH** – Internal crossing network for optimizing execution efficiency.
* **DWEB (Dealer Web)** – Dealer-based trading platform for RFQ (Request for Quote) and negotiated transactions.

**Historical & Real-Time Datasets**

Our analytics and execution models leverage a variety of datasets:

* **Order Book Data** – Real-time market depth from CLOB.
* **Trade Data** – Executed trade records from MATCH and DWEB.
* **Liquidity Metrics** – Spreads, impact costs, and order flow imbalances.
* **Execution Performance Data** – Used for pre-trade analysis, execution optimization, and transaction cost analysis (TCA).
