Exchange connectivity is the infrastructure that links a trading firm directly to a regulated exchange or lit trading venue, so it can submit orders to the venue’s matching engine and receive that venue’s market data. It is a specialized subset of market connectivity, distinguished by its focus on the venues that operate transparent, displayed order books – and by how much latency matters when accessing them.

A clear guide to the FIX protocol: how FIX sessions and messages work, key message types, and how it powers institutional market connectivity.

Every order an institutional desk sends has to reach somewhere – a broker, an exchange, a dark pool, a liquidity provider – and every price the desk acts on has to arrive from those same places, fast and intact. That two-way plumbing is market connectivity. It is the least glamorous layer of the trading stack and one of the most … Read More

On modern electronic markets, the gap between a profitable trade and a missed one is often measured in microseconds. Low-latency trading infrastructure is the stack of network, hardware, and software engineering built to win that race – to see a price change and act on it before anyone else does. It builds directly on the exchange connectivity layer, pushing every … Read More

A trade is not finished when the order is filled. The fill is the midpoint of a longer lifecycle that runs through the back office, where the trade is captured, allocated, confirmed, cleared, settled, and reconciled until cash and securities have actually changed hands. That sequence is post-trade processing – the unglamorous machinery that turns an execution into a completed, … Read More

An electronic order can leave a trading desk and reach a matching engine in microseconds. That speed is the point of modern trading – and also its danger. A mistyped quantity, a runaway algorithm, or a breached credit limit can do enormous damage before a human can react. Pre-trade risk controls are the automated guardrails that sit on the order’s … Read More

How your firm accesses market infrastructure determines your execution latency, risk exposure, and regulatory obligations. The distinction between Direct Market Access and Sponsored Access is not just technical – it defines who bears responsibility for pre-trade risk controls and what performance envelope is achievable. Getting this architecture decision right is foundational for any institutional trading desk building or upgrading its … Read More

Transaction cost analysis has evolved from a post-trade compliance exercise into a live execution management tool. For buy-side desks operating under MiFID II, the quality of your TCA data is directly linked to the quality of your execution infrastructure – and that infrastructure starts with the order and execution management system at the centre of your trading workflow. What Is … Read More

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

The choice between an OMS, an EMS, and a converged O/EMS is one of the most consequential architectural decisions a trading firm can make. It shapes latency, compliance posture, TCA data quality, and the total cost of maintaining your execution stack. Yet the distinctions between these three system types are often poorly understood — or conflated in vendor marketing. This … 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
