The Top 12 Smart Order Routing Technologies in 2024

Subscribe to our newsletter

Smart Order Routing (SOR), the automated process of directing orders to the most appropriate trading venue to achieve the best possible execution – typically using algorithms to analyse multiple factors, such as price, liquidity, speed and likelihood of execution, across various exchanges and trading platforms – has been a feature of electronic markets in some shape or form since their introduction in the 1990’s. As the growth of multiple trading venues and exchanges led to increased market fragmentation, and as regulatory changes such as Reg NMS in the US and MiFID in Europe emphasised best execution practices, early SOR systems emerged to navigate fragmented markets and optimise order execution.

Since then, advancements in technology and execution algorithms have continually enhanced SOR capabilities. Smart Order Routing has become more sophisticated, utilising real-time data and advanced analytics to navigate dark pools and other non-displayed trading venues, and it is now used to access liquidity in equities, fixed income, FX, and exchange-traded derivatives (ETDs).

Looking ahead, SOR will continue to be driven by technological advancements, regulatory changes, and market demands across multiple asset classes, including crypto and digital assets. Today, machine learning and artificial intelligence are steadily being integrated to improve SOR performance through predictive analytics, adaptive learning, and dynamic strategy adjustments.

TradingTech Insight has compiled a list of the top Smart Order Routing technology providers to consider in 2024. This list is based on a combination of A-Team Group research with entries and voting by our readership of SOR solution providers in our recent TradingTech Insight Awards USA and TradingTech Insight Awards Europe.

LIST FastTrade

Winner of Best SOR application 2024 in our Trading Tech Insight Awards (Europe)

LIST’s programmable Smart Order Router is designed to deploy best execution algorithms across trading venues and asset classes. It analyses market data, order details, and costs in real-time, and on an order-by-order basis. The SOR efficiently performs a pre-trade transaction cost analysis, considering liquidity, broker fees, venue taxes, speed of execution, and settlement to drive the order routing process successfully. The venue ranking algorithm can be customised based on clients’ needs and priorities, using features such as pre-trade market impact evaluations, forecasts of book movements, or past trade statistics for optimal counterparty selection. Detailed reporting provides proof of the decision-making process.



Winner of Best SOR application 2024 in our Trading Tech Insight Awards (US)

Overbond is an AI quantitative analytics provider for institutional fixed income capital markets. Overbond provides data aggregation solutions and a comprehensive suite of AI algorithms for bond pricing, trade workflow automation, pre-trade signals and market monitoring. A key element of Overbond’s SOR is its ability to work alongside existing O/EMS platforms. Overbond’s COBI-Pricing LIVE uses three layers of interoperability to automate trading: it ingests and aggregates data from multiple sources, it integrates with the legacy systems on the desk, and it communicates with electronic trading venues.

Overbond collaborated with partners from both the buy-side and sell-side to create the new SOR system for buy-side fixed income traders, which features AI-enhanced routing logic and allocates trades across multiple electronic trading venues and counterparties, based on price and liquidity, to achieve the best execution while minimising trading costs.

TORA’s rules-based Smart Order Routing capabilities allow clients to optimise their trade execution based on factors such as price, liquidity, speed, and market impact. By intelligently routing orders to the most suitable execution venue, TORA helps clients achieve better execution, reduce trading costs, and enhance overall trading performance.

The sophistication of TORA’s rules-based SOR lies in its granularity, which empowers traders to fine-tune their execution approach by defining rules based on factors such as trading strategy, venue, asset class, order size, market conditions, time of day, or various other criteria. TORA uses powerful, real-time transaction cost analysis (TCA), which helps determine which type of algo to use (VWAP, TWAP, volume participation, etc.), how long to track the market, algo parameters (such as slice size, slice quantity, number of child orders, etc.), and which liquidity types to use (e.g. lit venues, dark pools, etc.). This level of granularity allows traders to pro-actively respond to market dynamics, thereby improving the likelihood of optimal order execution.

A key facet of TORA’s rules-based SOR functionality its ability to rapidly adapt to market conditions and switch from one algorithm to another, either automatically or at the trader’s instigation. This ability to dynamically alter strategies, on-the-fly, ensures that order execution remains optimised, whatever the state of the market.



MarketAxess Adaptive Auto-X is a revolutionary fixed-income algo trading and SOR platform, powered by unique machine learning-based data signals, trained on market and proprietary MarketAxess data.

The routing technology is also able to connect to external liquidity pools in the future.

Offered as a suite of algos designed specifically for fixed income, including passive, aggressive and participation styles, clients can even customise algos while they are in progress. Although designed to be a no-touch solution with plug and play support for all major OMSs, a dedicated Adaptive Auto-X desktop app keeps traders in control by providing full transparency on the algo’s progress, allowing them to switch between fully automated or “trader-assist”.
