Bruce Markets Enters South Korea as Meritz Securities Taps Overnight U.S. Equity Data
By Lauren Towner · 14 September 2026

Quick Summary
Bruce Markets has partnered with Meritz Securities to launch its first overnight U.S. equities market data feed in South Korea. This integration allows Korean investors to access real-time pricing and liquidity data during the U.S. overnight session, effectively eliminating blind trading risks for retail and institutional participants in the region.
How Does the Meritz Securities Integration Prevent Blind Trading?
By connecting to the Bruce ATS data feed, Meritz Securities provides its clients with uninterrupted market visibility during the critical 8:00 p.m. to 4:00 a.m. ET window. This period coincides with the Korean business day, where demand for U.S. stocks has historically been high but often restricted to single-venue data. The integration ensures that Korean retail traders are no longer forced into "blind trading" when a specific venue halts a security. Instead, they gain a multi-venue pricing framework that offers a more complete view of U.S. equity activity. This is particularly vital given that Bruce Markets analysis showed overnight notional activity nearly doubled between November 2025 and March 2026. By diversifying data sources, Meritz ensures that its customers can make informed investment decisions even when primary venues face technical restrictions or fair access halts.
Why is Multi-Venue Access Critical for Overnight U.S. Equities?
The overnight U.S. equities market is maturing rapidly, requiring robust market infrastructure to handle increased volatility and volume. Recent market events have shown that relying on a single trading venue creates systemic liquidity risks. For instance, in September 2026, a single-venue halt affected five symbols that averaged over 15 million shares in daily volume. Bruce Markets addresses this by providing a high-performance alternative that bridges the gap between after-hours and pre-market sessions. Key metrics from the partnership include:
- 144% volume growth for Bruce ATS in Q2, reaching 1.16 billion shares.
- 20.77% market share of reported overnight notional value achieved in September.
- $391.2 billion notional traded across the top three overnight ATSs in Q2.
What Results Has Bruce ATS Delivered for Global Investors?
Bruce ATS has established itself as a credible liquidity source, with its share of monthly overnight volume rising from 11.66% to 16.4% in late 2026. The platform uses exchange-grade technology to provide a stable environment for extended trading hours. For Meritz Securities, this means offering a reliable trading experience that matches the sophistication of daytime markets. The growth is not just limited to data; executed notional value for Bruce ATS jumped 105% to $49.03 billion in a single quarter. This momentum proves that global institutional demand for 24/5 access to U.S. markets is no longer a niche requirement but a standard industry expectation. By front-loading transparency, Bruce Markets is redefining after-hours trading for the world's most active investor bases.
FF NEWS TAKE:
The expansion of overnight U.S. equities data into South Korea is a significant needle-mover for global market structure. For too long, the overnight session was a "black box" for international retail investors, leading to the dangerous blind trading scenarios mentioned by Bruce Markets. By securing Meritz Securities as a first-mover, Bruce is effectively democratizing institutional-grade data for the Korean market. This move signals that the era of single-venue dominance in overnight trading is ending, replaced by a resilient, multi-venue ecosystem that prioritizes investor protection and price discovery.
