Definition
A dark pool is a trading venue where orders are not displayed publicly before execution, allowing participants to trade large blocks without signaling intent to the broader market. Dark pools reduce market impact for large orders by hiding pre-trade quotes from other participants, post-trade reporting still flows to the tape or equivalent regulatory surface. In digital assets, dark pool functionality is often delivered through ATS-registered venues, OTC desks, or RFQ-based workflows that execute against committed liquidity rather than a public order book.
Example
A hedge fund needs to buy 2,000 BTC without moving the visible order book. The order is routed to a dark pool ATS where it matches against a counterparty's resting sell interest; the fill is reported post-trade without ever appearing in the pre-trade quote stream.
How Liquid Mercury Handles This
Mercury OTC supports dark-style execution via RFQ and bilateral workflows, and Mercury Pro integrates dark routing into its SOR for large-order handling when visible venue execution would cause adverse impact.
