Mean-Reversion & Order-Book-Adaptive Execution Platform
Marsbridge engineered a live execution platform that began as a mean-reversion engine and evolved into an order-book-adaptive framework. The stack ingests market depth, derives a central-price signal to guide order placement, and manages multi-venue orders with risk and reliability controls. The platform includes a cloud runtime, a configuration/database layer, continuous monitoring, and operational runbooks—delivered without disclosing proprietary trading rules.
Customer
Starting from a mean-reversion engine, the client sought execution intelligence that adapts to order-book conditions across regions and asset types—within realistic broker/data constraints and production-grade operations.
Challenge
- From quotes to decisions: Convert market-depth information into a robust central-price indicator to improve queue placement and reduce adverse selection.
- Data/venue constraints: Depth access varies by venue/provider; the platform must operate under connection and entitlement constraints.
- Operational realities: Opening/closing auctions, partial data, and roaming access can disrupt trading; guardrails are needed for reliability.
- Unified data hygiene: Maintain continuous futures and corporate-action-aware equities in the same environment for cross-asset visibility—without exposing instrument lists or roll rules.
Solution
Approach: A cross-functional squad—Quant/Tech Lead, Execution Engineer, Data/Infra Engineer, QA/Ops Analyst—delivered iteratively on cloud infrastructure.
Architecture & runtime
Hardened cloud nodes with secure remote access and entitlement management; centralized configuration + relational DB to manage instruments, parameters, and audit logs.
Order-book-adaptive execution
Built a depth-aware central price, standardized execution policy templates, and per-symbol depth acquisition modes to manage data constraints.
Cross-asset data hygiene
Integrated continuous futures series and dividend/corporate action updates into the runtime for consistent, cross-asset analytics.
Technologies & tools
Python services for ingestion, central-price modeling, orders, and monitoring
Broker API for orders/executions, market-data feeds for quotes and depth (vendors generalized)
Relational database for state, audit, and configuration, file artifacts for diagnostics and reviews
Process
- Kickoff & node prep — Cloud access, entitlements, parity checks with the existing research codebase.
- Book-model prototype — Implement depth-aware central price; calibrate parameters on a pilot symbol set.
- Execution refinements — Apply policy templates for placement/pacing; enable lot-sizing and visibility controls; add depth modes.
- Auction/edge-case guards — Introduce auction-aware protections and self-order filtering; stabilize behavior across venues.
- Data hygiene — Unify continuous-contract and dividend updates in the operational data plane; schedule quality checks.
- Go-live & iterate — Deploy, monitor, and refine based on diagnostics and operator feedback.
Team
Results
- Order-book awareness: Execution decisions incorporate depth conditions, improving consistency of queue placement and reducing avoidable adverse fills.
- Operational resilience: Depth-mode controls, auction protections, and hardened access support day-to-day reliability under data-plan constraints.
- Unified data plane: The same runtime maintains continuous futures and dividend updates for cross-asset oversight without exposing proprietary roll/adjustment rules.
Sanitization note: All indicator values, decay/weighting formulas, subscription counts, venue-specific behaviors, timing windows, symbol lists, and capital/lot rules have been intentionally generalized or removed.
