Expand TraderX Control Examples in CALM

[LeighFinegold]

Issue Description

The TraderX example in CALM has been progressively enhanced, first documented in #301 and later expanded with flows via PR #660.

This issue now aims to further develop TraderX by adding a plethora of control examples, showcasing realistic enforcement mechanisms across different control categories.

While #878 supports control documentation in JIRA, and #200 focused on documenting resiliency controls for TraderX, this issue will take a broader approach to defining multiple categories of controls that govern the entire system.

The goal is to make TraderX a comprehensive reference model for applying CALM controls, covering areas such as security, reliability, observability, regulatory compliance, and business workflows.

Proposed Expansion Areas

1. Performance & Scalability Controls

• Throughput control – TraderX enforcing rate limits for trade execution.
• Latency monitoring – Defining SLAs for order processing speed.
• Scalability policy – Autoscaling based on trade volume.

2. Reliability & Resilience Controls

• Failover mechanism – TraderX ensuring secondary systems handle order flow.
• Timeout policies – Retry logic for degraded service interactions.

3. Security & Access Controls

• Authentication enforcement – OAuth-based API authentication for trade requests.
• Data encryption controls – TraderX enforcing TLS 1.2+ for trade communication.
• Role-based access controls (RBAC) – Limiting order modification permissions.

4. Compliance & Risk Controls

• Regulatory compliance mapping – TraderX aligning with GDPR, SEC, MiFID II.
• SLA review policies – Defining periodic control audits to ensure compliance.

5. Observability & Monitoring Controls

• Logging and auditability – Ensuring TraderX logs trade requests in a structured format.
• Alerting and anomaly detection – Detecting suspicious trading patterns.

6. Data Handling & Processing Controls

• Trade data retention policy – Ensuring regulatory data storage requirements.
• Data transformation validation – Schema enforcement for order ingestion.

7. API & Integration Controls

• Schema validation enforcement – TraderX APIs ensuring JSON Schema validation.
• Dependency health checks – Monitoring third-party market data providers.

8. Incident Response & Recovery Controls

• Disaster recovery planning – Defining failover strategies for trade execution.
• Escalation paths for trade failures – Automated incident handling workflows.

9. Workflow & Process Controls

• Multi-stage approval workflows – TraderX requiring compliance sign-off for high-risk trades.
• Business logic enforcement – Ensuring price validation before executing trades.

Next Steps

• Expand TraderX control definitions to cover multiple domains.
• Ensure controls align with existing flows in TraderX.
• Validate against regulatory and operational best practices.

This initiative will help establish TraderX as a robust, real-world example of CALM controls in action.
