🎯 Objective

Comprehensive overhaul of statistics and analytics throughout the ProjectX SDK to provide accurate, performant, and actionable metrics.

📋 Problem Statement

Current statistics implementation has several critical gaps:

  • TradingSuite reports hardcoded zero values for API calls, cache metrics, and memory usage
  • Memory leaks in OrderManager storing unlimited timing data in lists
  • Inconsistent statistics tracking - not all managers use StatsTrackingMixin
  • Missing metrics for network quality, data validation, and performance percentiles
  • No aggregation of component statistics at the suite level

📚 Documentation

  • Detailed Implementation Plan
  • Full analysis available in Obsidian: Development/ProjectX SDK/Feature Planning/v3.2.1 Statistics and Analytics Overhaul.md

✨ Key Improvements

Enhanced Statistics Infrastructure

  • EnhancedStatsTrackingMixin: Async support, performance metrics, configurable retention
  • StatisticsAggregator: Central aggregation for TradingSuite with caching
  • Circular buffers: Prevent memory leaks in timing metrics
  • Automatic cleanup: Configurable retention policies

Component Updates

  • All managers inherit from enhanced mixin for consistency
  • Fix TradingSuite's hardcoded values with real metrics
  • Add WebSocket vs API operation tracking
  • Implement data quality and network metrics

Advanced Analytics

  • Real-time performance dashboard
  • Historical analytics with pluggable persistence
  • Alerting system for anomaly detection
  • Export capabilities (Prometheus, JSON, CSV)

✅ Implementation Checklist

Phase 1: Foundation (Week 1)

  • Create EnhancedStatsTrackingMixin with async support
  • Implement StatisticsAggregator for TradingSuite
  • Add circular buffer implementations
  • Create comprehensive unit tests
  • Performance benchmarks

Phase 2: Component Integration (Week 1-2)

  • Update OrderManager to use enhanced stats
  • Update PositionManager to use enhanced stats

Added safe_int() helper function to validate inputs before converting to integers,
preventing potential ValueError exceptions on unexpected input types.

The function handles:
- None values (returns default)
- int/float types (safely converts)
- Numeric strings (validates and converts)
- Invalid types (logs warning and returns default)

This addresses the input validation issue identified in PR review.
