Secure OAuth2 Token Exchange for High-Frequency Trading API

Design a robust Laravel middleware for managing OAuth2 token exchanges specifically for algorithmic trading platforms. Implement a dynamic token rotation mechanism that automatically refreshes access tokens within 30 seconds of expiration, with built-in circuit breaker logic to prevent trading interruptions. Include comprehensive error handling for network failures, implement detailed logging for compliance auditing, and ensure the solution can handle concurrent token requests from multiple trading algorithms simultaneously.
