Best Execution & Trading Controls
Strengthen execution governance with better data, monitoring and evidence.

Markets & Trading
Improve the technology, controls and workflows behind electronic execution.
Overview
Electronic execution connects trading logic with liquidity, routing, connectivity and control. Improvements need to account for how the full order lifecycle works in the markets the desk serves.
Capmark works with banks, brokers and trading firms across OMS, EMS and OEMS platforms, smart order routing, DMA and DEA, FIX connectivity, venue onboarding and execution quality.
Our support includes algorithmic testing, deployment controls and low-latency infrastructure. Quant Development & Trading Models provides complementary expertise in model design, prototyping and backtesting.
What we do
We design and deliver the order and execution management systems, smart order routing, direct market access and connectivity that carry electronic order flow across lit, dark and bilateral venues.
We design, build, configure and tune execution strategies, including VWAP, implementation shortfall, liquidity-seeking and close algorithms. We work on strategy logic, placement models, routing rules, platform build and post-trade tuning. For research-led model development, signal testing, pricing models or deeper backtesting, see Quant Development & Trading Models.
We build the controls that allow algorithms to run safely: testing and conformance environments, deployment and rollback controls, kill switches, approval records, inventories and production monitoring. We apply the same discipline to vendor and machine-learning algorithms.
We use transaction cost analysis and execution evidence to improve routing, algorithm selection and counterparty choices. The wider policy, monitoring and reporting framework sits under Best Execution & Trading Controls.
We assess co-location, venue proximity, network design and market-data infrastructure where latency affects execution. We measure latency end to end, so investment is directed to the points that improve trading performance.
What to expect
A Senior Practitioner leads from day one. The first weeks benchmark the execution stack, routing logic, venue connectivity and algo controls, then agree the target design before build.
Implementation runs in phases: connectivity and venue onboarding, algo configuration, control design, parallel testing, staged cutover and hypercare monitoring.
Engagements range from focused venue or algo work to full execution-stack and governance programmes.
Scope may cover a specific execution capability or change across the wider electronic trading environment.
Establish the current state, the constraints, the risks and the value at stake.
Shape the target model and the business case with the executives who own the outcome.
Stand up the team, the plan and the governance around the outcome.
Design, build and test the change, with the business alongside.
Cutover, hypercare and handover, so the business runs it under its own control.
