## CRITICAL: Testing and Running Examples
6+
7+
**ALWAYS use `./test.sh` to run tests and examples.** The environment variables are not set globally, but test.sh handles this automatically.
8+
9+
```bash
10+
# CORRECT - Always use test.sh:
11+
./test.sh examples/01_basic_client_connection.py
12+
./test.sh examples/21_statistics_usage.py
13+
./test.sh /tmp/test_script.py
14+
15+
# WRONG - Never use these directly:
16+
uv run python examples/01_basic_client_connection.py
17+
PROJECT_X_API_KEY="..." PROJECT_X_USERNAME="..." uv run python script.py
18+
```
19+
20+
The test.sh script properly configures all required environment variables. DO NOT attempt to set PROJECT_X_API_KEY or PROJECT_X_USERNAME manually.

**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
2+
3+
## Overview
4+
Comprehensive enhancement of statistics and analytics tracking across all ProjectX SDK components to provide accurate, performant, and actionable metrics.
5+
6+
## Motivation
7+
Current statistics implementation has several gaps:
8+
- TradingSuite reports hardcoded zero values for many metrics
9+
- Inconsistent use of StatsTrackingMixin across components
10+
- Potential memory leaks in OrderManager (unbounded lists)
11+
- Missing aggregation of component statistics
12+
- No network or data quality metrics
13+
14+
## Detailed Plan
15+
The full implementation plan is available in the Obsidian documentation:
16+
`Development/ProjectX SDK/Feature Planning/v3.2.1 Statistics and Analytics Overhaul.md`
17+
18+
## Key Improvements
19+
20+
### 1. Enhanced Statistics Infrastructure
21+
- **EnhancedStatsTrackingMixin**: Async support, performance metrics, configurable retention
22+
- **StatisticsAggregator**: Central aggregation for TradingSuite
23+
- **Circular buffers**: Prevent memory leaks in timing metrics
24+
25+
### 2. Component Updates
26+
- All managers to inherit from enhanced mixin
27+
- Fix TradingSuite hardcoded values
28+
- Add WebSocket vs API tracking
29+
- Implement data quality metrics
30+
31+
### 3. Advanced Analytics
32+
- Real-time performance dashboard
33+
- Historical analytics with persistence
34+
- Alerting system for anomalies
35+
- Export capabilities (Prometheus, JSON)
36+
37+
## Implementation Phases
38+
39+
### Phase 1: Foundation (Week 1) ✅ COMPLETE

41+
- [x] Implement StatisticsAggregator
42+

44+
45+
### Phase 2: Component Integration (Week 1-2) ✅ COMPLETE
46+

58+
59+
## API Changes
60+
61+
### New APIs (Non-breaking additions)
62+
```python
63+
# Enhanced statistics
64+
suite.get_detailed_stats() # Comprehensive stats with performance metrics
65+
suite.get_performance_dashboard() # Real-time dashboard
66+
suite.export_metrics(format="prometheus") # Export for monitoring
67+
68+
# Component enhancements
69+
manager.get_performance_metrics() # Detailed performance data
70+
manager.cleanup_old_stats() # Manual cleanup trigger
71+
```
72+
73+
### Backward Compatibility
74+
- All existing statistics APIs remain unchanged
75+
- New features are opt-in via configuration
76+
- Deprecation warnings for methods to be removed in v4.0
77+
78+
## Testing Strategy
79+
- Unit tests for each statistics component
80+
- Integration tests for aggregation
81+
- Performance benchmarks (< 2% overhead)
82+
- Memory leak detection (24h sustained load)
83+
- Data accuracy validation
84+
85+
## Configuration
86+
```python
87+
# Example configuration
88+
config = {
89+
"statistics": {
90+
"enabled": True,
91+
"level": "detailed", # basic | detailed | full
92+
"retention_hours": 24,
93+
"sampling_rate": 1.0,
94+
"enable_profiling": False,
95+
"cleanup_interval": 300 # seconds
96+
}
97+
}
98+
```
99+
100+
## Success Metrics
101+
- Performance overhead < 2% CPU
102+
- No memory leaks after 24h operation
103+
- 100% accurate statistics reporting
104+
- All components have comprehensive statistics
105+
- Clear, actionable metrics for users
106+
107+
## Questions for Review
108+
1. Should enhanced statistics be opt-in or enabled by default?
109+
2. Which persistence backends should we support initially?
110+
3. Priority for external monitoring integrations?
111+
4. Acceptable performance overhead threshold?
112+
113+
