+## Overview
+
+The UI Stability Fix implements a comprehensive solution to resolve critical stability issues between the dashboard UI and training processes. The design focuses on complete process isolation, proper async/await handling, resource conflict resolution, and robust error handling. The solution ensures that the dashboard can operate independently without affecting training system stability.

+
+### Process Isolation Design
+
+The system will implement complete process isolation using:
+
+1. **Separate Python Processes**: Dashboard and training run as independent processes
+2. **Inter-Process Communication**: File-based communication for status and data sharing
+3. **Resource Partitioning**: Separate resource allocation for each process
+4. **Independent Lifecycle Management**: Each process can start, stop, and restart independently
+
+### Async/Await Error Resolution
+
+The design addresses async issues through:
+
+1. **Proper Event Loop Management**: Single event loop per process with proper lifecycle
+2. **Async Context Isolation**: Separate async contexts for different components
+3. **Coroutine Handling**: Proper awaiting of all async operations
+4. **Exception Propagation**: Proper async exception handling and propagation
+

+# Requirements Document
+
+## Introduction
+
+The UI Stability Fix addresses critical issues where loading the dashboard UI crashes the training process and causes unhandled exceptions. The system currently suffers from async/await handling problems, threading conflicts, resource contention, and improper separation of concerns between the UI and training processes. This fix will ensure the dashboard can run independently without affecting the training system's stability.
+
+## Requirements
+
+### Requirement 1: Async/Await Error Resolution
+
+**User Story:** As a developer, I want the dashboard to properly handle async operations, so that unhandled exceptions don't crash the entire system.
+
+#### Acceptance Criteria
+
+1. WHEN the dashboard initializes THEN it SHALL properly handle all async operations without throwing "An asyncio.Future, a coroutine or an awaitable is required" errors.
+2. WHEN connecting to the orchestrator THEN the system SHALL use proper async/await patterns for all coroutine calls.
+3. WHEN starting COB integration THEN the system SHALL properly manage event loops without conflicts.
+4. WHEN handling trading decisions THEN async callbacks SHALL be properly awaited and handled.
+5. WHEN the dashboard starts THEN it SHALL not create multiple conflicting event loops.
+6. WHEN async operations fail THEN the system SHALL handle exceptions gracefully without crashing.
+
+### Requirement 2: Process Isolation
+
+**User Story:** As a user, I want the dashboard and training processes to run independently, so that UI issues don't affect training stability.
+
+#### Acceptance Criteria
+
+1. WHEN the dashboard starts THEN it SHALL run in a completely separate process from the training system.
+2. WHEN the dashboard crashes THEN the training process SHALL continue running unaffected.
+3. WHEN the training process encounters issues THEN the dashboard SHALL remain functional.
+4. WHEN both processes are running THEN they SHALL communicate only through well-defined interfaces (files, APIs, or message queues).
+5. WHEN either process restarts THEN the other process SHALL continue operating normally.
+6. WHEN resources are accessed THEN there SHALL be no direct shared memory or threading conflicts between processes.
+
+### Requirement 3: Resource Contention Resolution
+
+**User Story:** As a system administrator, I want to eliminate resource conflicts between UI and training, so that both can operate efficiently without interference.
+
+#### Acceptance Criteria
+
+1. WHEN both dashboard and training are running THEN they SHALL not compete for the same GPU resources.
+2. WHEN accessing data files THEN proper file locking SHALL prevent corruption or access conflicts.
+3. WHEN using network resources THEN rate limiting SHALL prevent API conflicts between processes.
+4. WHEN accessing model files THEN proper synchronization SHALL prevent read/write conflicts.
+5. WHEN logging THEN separate log files SHALL be used to prevent write conflicts.
+6. WHEN using temporary files THEN separate directories SHALL be used for each process.
+
+### Requirement 4: Threading Safety
+
+**User Story:** As a developer, I want all threading operations to be safe and properly managed, so that race conditions and deadlocks don't occur.
+
+#### Acceptance Criteria
+
+1. WHEN the dashboard uses threads THEN all shared data SHALL be properly synchronized.
+2. WHEN background updates run THEN they SHALL not interfere with main UI thread operations.
+3. WHEN stopping threads THEN proper cleanup SHALL occur without hanging or deadlocks.
+4. WHEN accessing shared resources THEN proper locking mechanisms SHALL be used.
+5. WHEN threads encounter exceptions THEN they SHALL be handled without crashing the main process.
+6. WHEN the dashboard shuts down THEN all threads SHALL be properly terminated.
+
+### Requirement 5: Error Handling and Recovery
+
+**User Story:** As a user, I want the system to handle errors gracefully and recover automatically, so that temporary issues don't cause permanent failures.
+
+#### Acceptance Criteria
+
+1. WHEN unhandled exceptions occur THEN they SHALL be caught and logged without crashing the process.
+2. WHEN network connections fail THEN the system SHALL retry with exponential backoff.
+3. WHEN data sources are unavailable THEN fallback mechanisms SHALL provide basic functionality.
+4. WHEN memory issues occur THEN the system SHALL free resources and continue operating.
+5. WHEN critical errors happen THEN the system SHALL attempt automatic recovery.
+6. WHEN recovery fails THEN the system SHALL provide clear error messages and graceful degradation.
+
+### Requirement 6: Monitoring and Diagnostics
+
+**User Story:** As a developer, I want comprehensive monitoring and diagnostics, so that I can quickly identify and resolve stability issues.
+
+#### Acceptance Criteria
+
+1. WHEN the system runs THEN it SHALL provide real-time health monitoring for all components.
+2. WHEN errors occur THEN detailed diagnostic information SHALL be logged with timestamps and context.
+3. WHEN performance issues arise THEN resource usage metrics SHALL be available.
+4. WHEN processes communicate THEN message flow SHALL be traceable for debugging.
+5. WHEN the system starts THEN startup diagnostics SHALL verify all components are working correctly.
+6. WHEN stability issues occur THEN automated alerts SHALL notify administrators.
+
+### Requirement 7: Configuration and Control
+
+**User Story:** As a system administrator, I want flexible configuration options, so that I can optimize system behavior for different environments.
+
+#### Acceptance Criteria
+
+1. WHEN configuring the system THEN separate configuration files SHALL be used for dashboard and training processes.
+2. WHEN adjusting resource limits THEN configuration SHALL allow tuning memory, CPU, and GPU usage.
+3. WHEN setting update intervals THEN dashboard refresh rates SHALL be configurable.
+4. WHEN enabling features THEN individual components SHALL be independently controllable.
+5. WHEN debugging THEN log levels SHALL be adjustable without restarting processes.
+6. WHEN deploying THEN environment-specific configurations SHALL be supported.
+
+### Requirement 8: Backward Compatibility
+
+**User Story:** As a user, I want the stability fixes to maintain existing functionality, so that current workflows continue to work.
+
+#### Acceptance Criteria
+
+1. WHEN the fixes are applied THEN all existing dashboard features SHALL continue to work.
+2. WHEN training processes run THEN they SHALL maintain the same interfaces and outputs.
+3. WHEN data is accessed THEN existing data formats SHALL remain compatible.
+4. WHEN APIs are used THEN existing endpoints SHALL continue to function.
+5. WHEN configurations are loaded THEN existing config files SHALL remain valid.
+6. WHEN the system upgrades THEN migration paths SHALL preserve user settings and data.
