Compliance Overview

The TLI system is designed to meet stringent regulatory requirements for financial trading systems, ensuring compliance with:

• SEC Rule 17a-4: Electronic records requirements
• FINRA Rule 4511: General record keeping requirements
• FINRA Rule 7440: Order audit trail system (OATS)
• SOX Section 404: Internal controls over financial reporting
• CFTC Regulation 1.31: Books and records requirements
• MiFID II: Transaction reporting requirements (where applicable)

Audit Trail Procedures

Complete Transaction Audit Trail

Order Lifecycle Tracking

Every order processed through the TLI system generates a complete audit trail:

use serde::{Deserialize, Serialize};
