+## CRITICAL: Testing and Running Examples
+
+**ALWAYS use `./test.sh` to run tests and examples.** The environment variables are not set globally, but test.sh handles this automatically. 
+
+```bash
+# CORRECT - Always use test.sh:
+./test.sh examples/01_basic_client_connection.py
+./test.sh examples/21_statistics_usage.py  
+./test.sh /tmp/test_script.py
+
+# WRONG - Never use these directly:
+uv run python examples/01_basic_client_connection.py
+PROJECT_X_API_KEY="..." PROJECT_X_USERNAME="..." uv run python script.py
+```
+
+The test.sh script properly configures all required environment variables. DO NOT attempt to set PROJECT_X_API_KEY or PROJECT_X_USERNAME manually.

 ## Project Status: v3.2.0 - Enhanced Type Safety Release
 
 **IMPORTANT**: This project uses a fully asynchronous architecture. All APIs are async-only, optimized for high-performance futures trading.

+# v3.2.1 Statistics and Analytics Overhaul
+
+## Overview
+Comprehensive enhancement of statistics and analytics tracking across all ProjectX SDK components to provide accurate, performant, and actionable metrics.
+
+## Motivation
+Current statistics implementation has several gaps:
+- TradingSuite reports hardcoded zero values for many metrics
+- Inconsistent use of StatsTrackingMixin across components
+- Potential memory leaks in OrderManager (unbounded lists)
+- Missing aggregation of component statistics
+- No network or data quality metrics
+
+## Detailed Plan
+The full implementation plan is available in the Obsidian documentation:
+`Development/ProjectX SDK/Feature Planning/v3.2.1 Statistics and Analytics Overhaul.md`
+
+## Key Improvements
+
+### 1. Enhanced Statistics Infrastructure
+- **EnhancedStatsTrackingMixin**: Async support, performance metrics, configurable retention
+- **StatisticsAggregator**: Central aggregation for TradingSuite
+- **Circular buffers**: Prevent memory leaks in timing metrics
+
+### 2. Component Updates
+- All managers to inherit from enhanced mixin
+- Fix TradingSuite hardcoded values
+- Add WebSocket vs API tracking
+- Implement data quality metrics
+
+### 3. Advanced Analytics
+- Real-time performance dashboard
+- Historical analytics with persistence
+- Alerting system for anomalies
+- Export capabilities (Prometheus, JSON)
+
+## Implementation Phases
+
+### Phase 1: Foundation (Week 1) ✅ COMPLETE
+- [x] Create EnhancedStatsTrackingMixin
+- [x] Implement StatisticsAggregator
+- [x] Add comprehensive unit tests
+- [x] PR review fixes (exception handling, PII sanitization, bounds checking)
+
+### Phase 2: Component Integration (Week 1-2) ✅ COMPLETE
+- [x] Update OrderManager with enhanced stats
+- [x] Update PositionManager with enhanced stats
+- [x] Update RealtimeDataManager with enhanced stats
+- [x] Fix TradingSuite statistics aggregation (fully integrated)
+- [x] Integration testing
+
+### Phase 3: Advanced Features (Week 2-3)
+- [ ] Implement PerformanceDashboard
+- [ ] Add HistoricalAnalytics
+- [ ] Create StatisticsAlerting
+- [ ] Documentation and examples
+- [ ] Performance testing
+
+## API Changes
+
+### New APIs (Non-breaking additions)
+```python
+# Enhanced statistics
+suite.get_detailed_stats()  # Comprehensive stats with performance metrics
+suite.get_performance_dashboard()  # Real-time dashboard
+suite.export_metrics(format="prometheus")  # Export for monitoring
+
+# Component enhancements
+manager.get_performance_metrics()  # Detailed performance data
+manager.cleanup_old_stats()  # Manual cleanup trigger
+```
+
+### Backward Compatibility
+- All existing statistics APIs remain unchanged
+- New features are opt-in via configuration
+- Deprecation warnings for methods to be removed in v4.0
+
+## Testing Strategy
+- Unit tests for each statistics component
+- Integration tests for aggregation
+- Performance benchmarks (< 2% overhead)
+- Memory leak detection (24h sustained load)
+- Data accuracy validation
+
+## Configuration
+```python
+# Example configuration
+config = {
+    "statistics": {
+        "enabled": True,
+        "level": "detailed",  # basic | detailed | full
+        "retention_hours": 24,
+        "sampling_rate": 1.0,
+        "enable_profiling": False,
+        "cleanup_interval": 300  # seconds
+    }
+}
+```
+
+## Success Metrics
+- Performance overhead < 2% CPU
+- No memory leaks after 24h operation
+- 100% accurate statistics reporting
+- All components have comprehensive statistics
+- Clear, actionable metrics for users
+
+## Questions for Review
+1. Should enhanced statistics be opt-in or enabled by default?
+2. Which persistence backends should we support initially?
+3. Priority for external monitoring integrations?
+4. Acceptable performance overhead threshold?
+
+## Progress Updates
+
+### Session 4 (2025-08-18): Phase 2 Component Integration Complete
+
+**Accomplishments:**
+- ✅ Updated PositionManager to use EnhancedStatsTrackingMixin
+- ✅ Updated RealtimeDataManager to use EnhancedStatsTrackingMixin
+- ✅ Added operation timing tracking to key methods
+- ✅ Verified TradingSuite aggregation properly configured
+- ✅ Created integration tests for component statistics
+- ✅ Created example script demonstrating enhanced statistics
+- ✅ Fixed async/await issues in statistics aggregator
+
+**Key Changes:**
+- PositionManager now tracks cache hits/misses and operation timings
+- RealtimeDataManager tracks tick/quote processing with metrics
+- All components properly inherit from EnhancedStatsTrackingMixin
+- StatisticsAggregator handles both sync and async methods gracefully
+- Integration tests verify statistics are being collected
+
+**Files Modified:**

+
+**Next Steps:**
+- Phase 3: Implement advanced features (dashboard, historical analytics)
+- Add more comprehensive integration tests
+- Performance testing under load
+- Documentation updates
+
+### Session 3 (2025-01-18): PR Review Fixes Complete

+- ✅ All linting and type issues resolved
+
+**Key Improvements:**
+- Circular buffers prevent memory leaks (deque with maxlen)
+- Thread-safe operations with asyncio locks
+- Performance metrics with percentiles (P50, P95, P99)
+- Prometheus export format support
+- Graceful degradation on component failures
+
+**Performance Validated:**
