Why Trade with us

In an increasingly complex market structure, achieving best execution requires rigor

Research-driven product innovation

Our limit order model, dark framework, and queue-jumping logic all started as research questions. Before we build, we find the root cause of a problem, study market behavior and simulate proposed solutions.

Fill-level scrutiny

As we optimize algo performance, we examine individual fills across venues, times of day, volatility regimes, and urgencies. This painstaking analysis helps us derive the right strategies for your flow.

Evolution with markets

For us, algorithm design is a process that meets the moment, not a one-time project. As markets change, strategies must be adapted to continue delivering optimal outcomes.

An extension of your trading desk

The same people who drive our research work as an extension of your trading desk to optimize for your unique order flow. We're laser-focused on your trading from the moment orders arrive through post-trade TCA.

Transparency in every layer of execution

Execution algorithms don't have to be a black box. Our research for buy-side clients shares the evidence behind our algorithm design, mapping the journey from the root of the problem to the solution we provide.

algo DNA

Problem-centered research powers every algorithm we offer

Problem & Solution

Most algos use heuristics that reprice limit orders without accounting for liquidity or volatility, inflating the cost of every passive fill.

The heart of our algorithms is a proprietary limit order model, grounded in academic research, pricing limit orders similarly to options theory, optimally accounting for expected adverse selection and maximizing spread capture.

The BestEx Research limit order model takes in the characteristics of the product being traded, including volatility, speed of trading, and more, and returns a recommended limit price for each child order with the specified fill probability.

problem & solution

The ATS landscape has evolved, increasing toxicity and information leakage and leading to higher trading costs.

Our dark liquidity curation framework incorporates ATS segmentation, tactic selection, proprietary signals, and conditional orders strategically to avoid toxic interactions and minimize information leakage. Curator, our dark algorithm, is built on this framework.

Venue segmentation is effective but the magnitude varies. The chart above illustrates comparison of Full Pool to Tier 1 (highest quality) at corresponding pool.

problem & solution

In a fragmented market with many exchanges, even an optimally priced child order can languish in a long or slow-moving exchange queue and face high adverse selection.

Our proprietary queue-jumping logic evaluates over 65,000 combinations of top-of-book exchanges, ranking venues by their likelihood of attracting market orders so our algo orders can jump the queue and avoid adverse selection. This model supports all algorithms trading on exchanges.

The WinMatrix
summarizes exchange competitiveness. The black box highlighted above indicates that for this stock, NYSE receives a market order 44% of the time when it and NASDAQ BX are competing (BX is inverted).
