Event Correlation -- Always use `correlation_id` to link related events -- Generate unique correlation IDs for each trading flow -- Include correlation IDs in all related events (trading, risk, audit) - -### 2. Latency Tracking -- Record processing timestamps at key points -- Calculate and store latency in nanoseconds -- Use for performance optimization and SLA monitoring - -### 3. Data Retention -- Follow regulatory requirements for retention periods -- Use automated partition management -- Archive old data to cold storage as needed - -### 4. Indexing Strategy -- Use time-based partitioning for all event tables -- Index on frequently queried columns (symbol, account_id, event_type) -- Consider partial indexes for optional fields - -### 5. Compliance Considerations -- Mark regulatory-impact events in audit trail -- Ensure immutable event records (no updates/deletes) -- Include sufficient context for regulatory inquiries -- Track all configuration changes with before/after values - -## Monitoring and Alerting - -### Key Metrics to Monitor -1. **Event Volume**: Events per second by type -2. **Latency**: Processing latency distribution -3. **Storage Growth**: Disk usage and partition sizes -4. **Data Quality**: Missing events or data integrity issues -5. **Compliance**: Unresolved risk events and pending approvals - -### Recommended Alerts -- Risk events with severity 'critical' or 'error' -- Trading latency exceeding SLA thresholds -- Failed event insertions -- Partition creation failures -- Audit trail events requiring approval \ No newline at end of file diff --git a/ml/src/stress_testing/HARDCODED_PRICES_ELIMINATION_REPORT.md b/ml/src/stress_testing/HARDCODED_PRICES_ELIMINATION_REPORT.md deleted file mode 100644 index ca08b8f7e..000000000 --- a/ml/src/stress_testing/HARDCODED_PRICES_ELIMINATION_REPORT.md +++ /dev/null @@ -1,171 +0,0 @@ -# Hardcoded Prices Elimination Report - -## Summary -Successfully eliminated hardcoded prices in `ml/src/stress_testing/market_simulator.rs` and replaced with a comprehensive configuration-driven approach. - -## Changes Made - -### 1.
