Traderson the buy side continue to adopt a segregated approach for their Order Management Systems (OMS) and Execution Management Systems (EMS).

In a recent analysis by Crisil Coalition Greenwich, it has been revealed that the majority of buy-side traders prefer to use separate Order Management Systems (OMS) and Execution Management Systems (EMS) rather than integrated platforms that combine both functions into a single OEMS system.

The study, titled "U.S. Equities OEMS 2025: The Buy-Side View," focuses on the views and preferences of buy-side traders regarding equity trading systems. The preference for separate OMS and EMS systems is driven by the need for greater control, flexibility, and customization in trading workflows, despite integrated solutions offering convenience and potential cost savings.

Key trader priorities when selecting OMS and EMS solutions include performance, ease of integration, speed and reliability, advanced analytics, and pre-trade insights. These factors are crucial for supporting complex workflows, making fast and reliable decisions, and managing risks effectively.

Leading providers of EMS, such as Bloomberg's EMSX and Virtu's Triton, are experiencing growth due to this trend. However, providers that emphasize specialized, stand-alone OMS and EMS platforms with robust integration capabilities currently lead the market share among buy-side traders.

Broadridge, for example, has enhanced its OMS and EMS offerings by integrating advanced pre-trade analytics from BMLL Technologies. This integration delivers actionable insights such as market impact forecasts, real-time volume metrics, volatility and risk scoring, and automated order routing that dynamically adapt to market conditions. This data-driven, seamless connectivity is highly valued for improving trading performance and workflow efficiency.

Established brands like top OMS providers Charles River and Bloomberg's AIM are also benefiting from this tendency. Customer support, ease of customization, and ease of use and intuitiveness are also important factors for traders.

Despite some buy-side traders opting for integrated platforms, most traders remain hesitant to migrate to new systems due to the risks and resources required. Jesse Forster, Senior Analyst at Crisil Coalition Greenwich, believes that the benefits of specialized systems outweigh the potential advantages of consolidated platforms for now.

In summary, the study offers guidance to technology providers developing OMS and EMS products. A clear majority of buy-side traders prefer to use separate OMS and EMS, as opposed to a single, integrated platform. Buy-side traders value control, flexibility, and customization in their trading platforms, and prioritize performance, easy integration, speed, reliability, and seamless connectivity in their systems.

1. The preference for separate Order Management Systems (OMS) and Execution Management Systems (EMS) among buy-side traders is driven by the need for greater control, flexibility, and customization in trading workflows, even when integrated solutions offer convenience and potential cost savings.
2. Leading fintech companies, such as Bloomberg, Virtu, and Broadridge, are experiencing growth in their EMS offerings due to the trend towards separate OMS and EMS platforms, with Broadridge enhancing its OMS and EMS solutions through advanced pre-trade analytics from BMLL Technologies.
3. Despite some buy-side traders opting for integrated platforms, most traders remain skeptical of migrating to new systems due to the risks and resources required. This suggests that specialized systems currently hold an advantage over consolidated platforms for buy-side trading, according to Jesse Forster, Senior Analyst at Crisil Coalition Greenwich.
