Definition
Liquidity aggregation is the process of combining order book and execution capacity from multiple venues into a single consolidated view that a trader or routing engine can act on. In digital asset markets, where there is no consolidated tape, every institutional trading stack must perform its own aggregation across centralized exchanges, decentralized venues, and OTC desks. The quality of the aggregation layer (latency, depth coverage, data accuracy, venue failover) is one of the central differentiators between institutional and retail trading platforms.
Example
A prop desk sees a single consolidated BTC/USDT order book representing real-time depth from 50+ venues, with each price level tagged by venue. The trader or SOR engine acts on the aggregated view rather than checking venues manually.
How Liquid Mercury Handles This
Mercury Pro maintains persistent, normalized connectivity to institutional venues with sub-millisecond aggregation, venue health monitoring, and failover logic. The aggregated view feeds the SOR engine and the TCA framework as a single source of truth.
