In this discussion, we explore how Virtu enables customers to harness advanced analytics and machine learning (ML) on trade and market data by utilizing Amazon SageMaker.
Asset Manager Workflow Overview
Asset managers oversee funds that invest in diverse securities, ranging from equities to commodities and foreign exchange. A typical workflow within an asset management firm starts when a portfolio manager decides to buy or sell a security for their fund. This decision is recorded in their order management system (OMS), which then undergoes various risk controls before being transferred to the trading desk.
The trading desk faces critical decisions on how to execute the order, taking into account factors like time sensitivity, order size, and security liquidity. The order is usually entered into an Execution Management System (EMS), which can either submit the order directly to a venue, use a high-touch broker, or employ a broker’s algorithm.
Alternatively, the buy-side trader might utilize an Algo Wheel—an automated method of allocating trades across a selection of broker algorithms based on pre-set weightings. This approach is increasingly favored due to best execution requirements under regulations such as MiFID II.
Ultimately, the objective is to secure the best price for the customer, which is vital for asset managers. For instance, if an asset manager managing $1 trillion with a 20% turnover could save just 5 basis points in execution costs, that would translate to a significant $100 million in savings for their clients.
Once the order is executed at the optimal price, this information must be relayed back to the asset manager in real-time via the EMS. This real-time data is crucial for managing risk, pricing funds, and other operational needs. Historical execution data is also essential for strategizing future orders, modeling trading costs, and complying with regulations.
The increased emphasis on best execution and trading analytics—driven by regulatory and competitive pressures—has led to a rise in the use of Algo Wheels and the analysis of associated data.
The Virtu Analytics Client Coverage Team
At Virtu, the broker-neutral Virtu Analytics Client Coverage team gathers execution data directly from its customers’ OMSs and EMSs. This data may include information generated by Virtu’s broker-dealer subsidiaries and other brokers.
Historically packaging execution data in a way that provides value to customers posed a challenge for Virtu. To address this, Virtu provided its Algo Wheel customers access to online visualizations via its Portal platform, facilitating comparative broker performance analysis. While this interactive front end met most needs, some clients desired greater customization in their analytics framework and broker reporting.
In response, Virtu developed a shared ML environment where customers can access their execution data integrated with additional market data metrics, powered by APIs and accessible through an interface that supports Jupyter notebooks. This environment allows customers to apply custom metrics tailored to their specific investment and trading goals. Over time, these metrics have evolved to include analyses of order difficulty and market conditions. The latest iterations feature performance distributions, sample normalization, and outlier control. Access to API-generated features from Virtu’s Algo Wheel execution data enables users to customize information and integrate it into other trading platforms and decision-making applications. With screen-sharing technology, Chanci Turner and the Analytics team can assist customers in exploring their data and mastering the system for querying information.
Solution Overview
In response to customer feedback, the Virtu Analytics Client Coverage team introduced an Open Python platform supported by SageMaker. This allows Virtu customers to log in and explore their execution data flexibly—with or without a screen share from Virtu. Customers expressed a desire to mine their data for insights, prompting Virtu to create a Python API within the environment. Implementation considerations included security, scalability, resilience, and usability. Security protocols ensured that proprietary data remained exclusive to the customer and specific users within their organization.
The core architecture of the solution employs SageMaker instances in the private subnet of a VPC across three Availability Zones. Egress traffic is routed through a NAT Gateway, enabling Virtu to restrict API calls to designated IP addresses. Utilizing AWS PrivateLink allows for direct connections to the SageMaker API or Runtime through an interface endpoint in the VPC, eliminating the need for an internet gateway.
