Nicholas Pratt talks with two leading providers to see what’s fuelling the continued popularity of ECNs and why they continue to play a critical role in FX trading.
ECNs are fast-reaching indispensable status with FX traders. The BIS triennial survey, which covered 2022 to 2025, showed that FX volumes grew by 30% in those three years, reaching a peak of $9.6 trillion in daily turnover. There was also an increase in the amount of electronic trading in that time, correcting a fall in volume from the previous survey in 2022. And FX spot volumes, primarily traded via ECNs, increased by roughly 40% in that time.
Meanwhile, a survey of 100 FX trading desks conducted by Euronext FX attempted to find out why. It found that the most valuable feature, as cited by 56% of respondents, was access to data. The demand for diverse liquidity sources and comprehensive trading platforms also featured as drivers, underlining what Euronext FX describes as “the critical role of ECNs in modern FX trading”.
ECNs remain popular with the buyside because they deliver what institutional traders value most, says Brian Andreyko, chief product officer at MEX Exchange, an ECN for spot FX, precious metals and commodities.
“ECNs provide transparent pricing, tighter spreads, and execution quality that increasingly mirrors what they are used to in equities. Aggregated liquidity and clear, datarich order books give asset managers greater confidence in the prices they’re trading on, while competitive makertaker dynamics consistently drive tighter, more efficient pricing. At the same time, reduced information leakage and stronger best execution auditability address two of the buy-side’s longstanding concerns in FX. Together, these factors have positioned ECNs as the natural venue for buyside FX flow,” says Andreyko.
“ECNs that can combine transparency, surveillance, and robust reporting will define the next phase of institutional FX infrastructure.”

ECNs are also increasingly attractive for institutional FX trading firms as the market continues to expand across both products and geographies, says Andreyko. “As more asset classes and emerging market currencies become fully electronic, institutions are prioritizing transparent pricing, tighter and more consistent spreads, and access to deeper, more diverse liquidity pools. ECNs deliver this through a deterministic, low leakage execution environment that aligns with modern, automated trading workflows.”
In fact, it was this trend that inspired the creation of MEX Exchange, says Andreyko. “We identified a clear need for ECN grade transparency and execution quality not just in core markets, but in regions that have historically been underserved. Our model extends ECN infrastructure into emerging markets across the GCC, Asia, and LATAM, providing institutions with access to markets that are rapidly electronifying and becoming increasingly central to global FX trading.”
The ability to customize liquidity pools has become central to the ECN value proposition because no two institutional trading firms want the same liquidity profile, says Andreyko. “There’s no onesizefitsall approach in FX, different strategies, time horizons, and risk tolerances demand different combinations of bank, non-bank, regional, and systematic liquidity. That’s why the ability to tailor pools, by counterparty, geography, product, or trading style, directly strengthens execution quality. Some firms have taken this a stage further by offering both an ECN and bilateral connectivity, or the best of both worlds, as the providers would have it – ECN grade transparency and matching when required, alongside direct, relationship driven liquidity when that is more appropriate. “This flexibility is key not only for developed but for emerging participants as well,” says Andreyko.
The ability for ECNs to help build credit lines has been another attraction for market participants looking to improve both their risk management and access to liquidity. This is done by centralising and standardising how credit is allocated across multiple liquidity providers, says Andreyko.
“By routing trading activity through a single, transparent venue, firms can demonstrate clean execution quality, controlled risk, and predictable behaviour, making it easier for prime brokers to extend or increase credit. Stronger credit lines translate directly into more effective risk management and deeper liquidity access. With greater credit capacity, firms can engage a broader set of bank and nonbank liquidity providers, trade larger sizes with confidence, and remain resilient during volatile markets or during period of market stress,” says Andreyko.
ECNs are the natural venue for buyside FX flow
“At MEX Exchange, we’ve taken a deliberate approach to this by working closely with global prime brokers to support institutional clients in developing and scaling their credit lines. Where traditional PB coverage leaves off, MEX Prime picks up, extending credit downstream and ensuring clients can access the full depth of our liquidity. This integrated approach gives us one of the most robust ECN credit infrastructures in the world, and it’s a key factor behind growing institutional adoption of our platform,” says Andreyko.
Alignment with algorithmic trading is another way for ECNs to maintain their popularity with participants, says Andreyko. “ECNs are a natural fit for algorithmic trading because algos rely on consistent, transparent, and highquality pricing to perform effectively. They require stable spreads, predictable matching logic, and reliable market data, without which execution models begin to degrade. ECNs provide this structure, which is why they’ve become the backbone of modern automated FX trading.”
This is even more critical in emerging and frontier markets, where liquidity is often fragmented and pricing less consistent, says Andreyko. “As these markets continue to electronify, algos require an ECN environment that brings order, transparency, and consistency to the workflow. That’s exactly what MEX Exchange is built for. We’ve designed our ECN to support algorithmic trading not just in major currencies, but across emerging market products where the need for clean, dependable pricing is even more pronounced.”
Compliance with best execution has become a key focus for ECN providers
Anonymity and reduced signaling are critical for FX firms today, especially in emerging and frontier markets that continue to electronify, and ECNs are designed to deliver both, says Andreyko. “By removing counterparty identity of the trading firm from the quotes and trades, ECNs prevent counterparties from inferring strategy, inventory pressure, or execution intent. That dramatically reduces signaling risk, protects alpha, and avoids the type of behavioral profiling often seen in bilateral markets.
“ECNs also minimize information leakage through neutral matching logic and separating pretrade data from counterparty identity. This gives firms greater confidence to execute larger or more sensitive flows without materially impacting the market or revealing their position,” says Andreyko.
ECNs have also evolved into critical data engines because they capture clean, highquality, timestamped information across pricing, liquidity, and market behaviour, says Andreyko. Trading firms are leveraging this to rigorously back-test strategies, calibrate execution models, and develop far more sophisticated analytics.
“As AI-driven and machine learning strategies continue to scale across trading desks, the need for deep, transparent, and consistent data becomes non-negotiable, algorithms can’t learn or adapt without a reliable historical and realtime data foundation,” says Andreyko.
“This is particularly impactful in emerging and frontier markets, where data has historically been sparse or inconsistent. As these markets electronify, ECN data is enabling firms to properly model liquidity conditions, understand market microstructure at a granular level, and deploy more sophisticated strategies with a level of confidence that simply wasn’t possible before.”
Regulatory mandates are also helpful in driving adoption of certain technologies, platforms or services. ECNs have become instrumental in helping firms meet institutional best execution requirements by providing transparent pricing, auditable execution data, and consistent access to liquidity, says Andreyko.
“The ability to capture and analyze detailed trade and market data allows firms to evidence execution quality in a way that aligns directly with regulatory and internal governance expectations. As a result, we’re seeing a clear shift across the industry towards greater alignment with the FX Global Code, alongside increased investment in surveillance, reporting, and analytics.”
Compliance with best execution has become a key focus for ECN providers as they continue to invest in their offerings and the tools and infrastructure required to provide clients with a fully transparent, datadriven view of their execution outcomes.
“As workflows become more automated and emerging markets continue to electronify, these governance features aren’t optional, they’re a baseline requirement. ECNs that can combine transparency, surveillance, and robust reporting will define the next phase of institutional FX infrastructure.”
ECNs will also have to invest in new technology if they are to succeed and significant progress has been made, according to Andreyko. “The most meaningful advances have been in core matching architecture, increasing the speed at which modern ECNs now operate. This dramatically reduces latency, slippage, and signaling risk, while improving overall execution consistency,” says Andreyko. “Beyond this, there has been a clear shift towards more intelligent execution frameworks, including AIdriven algorithms and smartorderrouting systems that learn from market conditions in real time.”
Sustained growth
According to Vidura Seneviratne, head of spot strategy 360T, ECNs are set for sustained growth because institutional FX execution is becoming more electronic, data-driven and workflow-integrated. “Clients increasingly want venues that combine speed, liquidity choice, anonymity, credit access, execution quality analytics and governance,” says Seneviratne. “The next phase of ECN growth will not only be about tighter spreads or lower latency, but about creating sustainable, measurable and customizable liquidity ecosystems where buy-side firms, systematic traders and liquidity providers can interact with greater confidence.”
ECNs are increasingly attractive to institutional FX trading firms because they provide fast, reliable, scalable and predictable execution environments, says Seneviratne. “Systematic firms and algo desks value not only pricing but also whether execution behaviour is consistent enough to be modelled, validated and routed to with confidence, while ECNs offer flexible access to deep liquidity through sweepable liquidity, full amount liquidity, firm orders, pegged orders, match-at-mid and semi-disclosed workflows.
“Modern ECNs also allow firms to optimize order placement, liquidity interaction, latency, signalling and market impact, with GTX focused on deterministic execution, unique curated liquidity and controlled economics, alongside a strategy to combine the 360T client franchise with the anonymous ECN ecosystem.”
“Trading firms increasingly use ECN data to improve routing logic, optimize algos, select liquidity pools and assess the true cost of liquidity.”

The ability to customize liquidity pools is central to the modern ECN value proposition because different clients prioritise different outcomes, including tighter spreads, lower market impact, full amount liquidity, firm liquidity, regional liquidity, skew-safe pools or specific LP types, says Seneviratne.
“Customisation also benefits LPs by aligning liquidity provision with client behaviour and contribution, allowing them to price more confidently and sustainably. At 360TGTX, liquidity management is increasingly systematic and data-driven, using key performance indicators (KPIs), monitoring tools and automated workflows to create sustainable liquidity pools for both makers and takers.”
ECNs also help build credit access by simplifying workflow, permissioning and relationship management in disclosed D2C models, while anonymous ECNs extend liquidity access through established credit arrangements, prime brokers, credit hubs and prime-of-prime structures, says Seneviratne. “This is particularly valuable for clients with strong trading demand but limited bilateral credit relationships with LPs. At 360TGTX, a key focus is helping credit-constrained clients access suitable credit solutions to unlock broader liquidity access and improve risk management flexibility.”
ECNs are also able to reduce signalling by allowing participants to access liquidity anonymously or semi-anonymously without revealing their identity or full trading intentions to the wider market, says Seneviratne. “This is particularly important for large orders, systematic strategies and clients sensitive to information leakage. Anonymous and semi-disclosed models also benefit LPs by protecting pricing, skew and liquidity provision, making robust due diligence, behavioral monitoring, permissioning and leakage protection increasingly important. 360TGTX places a strong focus on skew-safe liquidity and leakage protection to help LPs provide tighter and more tailored pricing while preserving market integrity,” he states.
ECNs have become valuable sources of execution and liquidity data, generating insights into response times, fill ratios, reject rates, market impact and post-trade performance, says Seneviratne.
“This helps firms combat fragmentation by providing a clearer view of available liquidity and its behaviour, while anonymous ECNs can deliver rich liquidity characteristics without revealing sensitive trading information. Trading firms increasingly use ECN data to improve routing logic, optimize algos, select liquidity pools and assess the true cost of liquidity, with sophisticated participants relying on pre- and post-trade analytics to achieve more predictable execution outcomes and reduce the gap between expected and realised execution performance.”
ECNs have also invested heavily in low-latency infrastructure, resilient matching technology, enhanced market data distribution and richer analytics, with the focus evolving from simply being fast to being fast, deterministic, measurable and reliable.
“At 360TGTX, this has included latency improvements, low-latency gateways, pegged order functionality, expanded firm liquidity and tools for systematic liquidity management,” says Seneviratne. “GTX is also exploring AI-enabled analytics, including lead-lag analysis, behavioural profiling and simulation, to support more scalable, data-driven liquidity management and improved client engagement.”
