The question every buy-side CTO faces when modernising the trading stack: bolt a specialist execution management system onto your existing OMS, or replace both with a converged O/EMS that handles the full order lifecycle in one platform? Both paths are commercially viable. The answer depends on your firm’s legacy commitments, asset class scope, and long-term operational cost tolerance. What “Best-of-Breed” … Read More

Modern equity markets are not a single place. A large institutional order touching a public exchange today immediately signals intent to thousands of competing participants — and the cost of that signal can dwarf the nominal commission paid. The parallel existence of transparent lit markets and opaque dark pools is not an accident: it is the structural response to a … Read More

Market fragmentation — the distribution of liquidity across dozens of exchanges, MTFs, dark pools, and internalisation engines — is one of the defining structural features of modern electronic markets. For institutional traders, this fragmentation creates both opportunity and obligation: the opportunity to source liquidity at better prices, and the regulatory obligation to demonstrate that they have done so systematically.

The smart order routing system is often described as the most technically demanding component of an execution management system. It operates at the intersection of market microstructure, real-time data engineering, and machine learning — making routing decisions in microseconds based on a continuously updated model of the liquidity landscape.

Both sit at the heart of modern electronic trading, yet they solve distinct problems and operate at different layers of the execution stack.

For many years, these systems operated in parallel — connected by integrations, but fundamentally separate. Today, a … Read More

Trading firms are rethinking their technology stack in 2026 because traditional approaches to building trading infrastructure no longer align with the demands of modern electronic markets. As execution becomes more complex, data-driven, and latency-sensitive, firms must decide whether to build systems in-house, buy existing solutions, or compose modular architectures combining best-of-breed components. This decision has direct implications on execution performance, … Read More
