DxFeed Launches Aggregated Overnight Market Data Feed for US Equities

Why It Matters

The feed fills a critical data gap in a market where overnight volume now approaches 9% of daily activity, enabling more accurate pricing and faster execution for global participants.

Key Takeaways

• Overnight volume reaches roughly 9% of total U.S. equity activity
• dxFeed aggregates Level 1 data across three major ATS venues
• Continuous 24/7 feed removes need for multiple data sources
• Improved transparency boosts price discovery in low‑liquidity periods

Pulse Analysis

The rise of extended‑hours trading reflects a broader shift toward a truly global, always‑on equity market. Investors in Asia, Europe, and the U.S. increasingly rely on pre‑ and post‑market liquidity to manage risk and capture opportunities, pushing overnight volume toward double‑digit percentages of daily flow. Yet, until now, data providers have offered fragmented, venue‑specific feeds that require costly integration and introduce latency, limiting the usefulness of off‑hour price signals.

dxFeed’s Aggregated Overnight Feed tackles this fragmentation by normalizing Level 1 information from key alternative trading systems and presenting it in a single, consistent schema. The proprietary Feed Consolidator Service merges quotes, trades, and time‑and‑sales into a real‑time stream that aligns with regular‑session data. For quantitative strategies that depend on high‑frequency inputs, the reduction in infrastructure overhead translates directly into lower operational risk and faster model execution, unlocking alpha that was previously hidden in disparate data silos.

Beyond the immediate technical benefits, the feed signals a maturation of market infrastructure that could accelerate the adoption of 24/7 trading models. As transparency improves, more institutional participants are likely to allocate capital to overnight strategies, potentially increasing depth and narrowing spreads. This evolution also supports regulators’ goals of market fairness by providing a clearer view of liquidity across all trading hours, setting a new benchmark for data quality in the modern equity ecosystem.
