Detection Engine Hardening Plan
Objectives
Ensure the detection pipeline produces actionable opportunities with production-grade heuristics and hands them off to the execution stack automatically. Current implementation primarily logs opportunities and uses simplified scoring parameters.
Action Items
-
Opportunity Scoring & Filtering
- Define canonical scoring function (profitability, confidence, liquidity, latency) aligned with business thresholds.
- Replace ad-hoc ROI/price-impact checks with configurable policies (pull from config/env).
- Add regression tests covering borderline cases (low confidence, high slippage, gas-constrained opportunities).
-
Execution Handoff
- Implement direct handoff to
ArbitrageExecutorvia callback (seeSetOpportunityHandler). - Ensure backpressure handling (bounded queue, metrics when saturated).
- Introduce retry/backoff for transient execution failures.
- Implement direct handoff to
-
Concurrency & Worker Pools
- Review
WorkerPoolsizing, ensure graceful shutdown and error propagation. - Add instrumentation (metrics/logs) for scan time, queue depth, dropped opportunities.
- Review
-
Historical Validation
- Replay recorded blocks/datasets to validate hit rate and false positives.
- Store misclassified opportunities for manual review.
-
Configuration & Docs
- Centralise detection thresholds in config files (
config/*.yaml) and document indocs/5_development/CONFIGURATION.md. - Update runbooks to describe detection tuning knobs and alerting thresholds.
- Centralise detection thresholds in config files (
