Performance Tracking Layers¶

Layer 1: Trade Recording - Real-time Trade Capture: Instant recording of all executed trades - Market Context Integration: Market conditions at trade execution - Account State Tracking: Account status during trade execution

Layer 2: Trade Labeling - Behavioral Classification: Trend-following, mean-reversion, momentum - Market Environment Tags: Volatility regime, market session, news events - Strategy Pattern Recognition: Entry/exit timing, position sizing patterns

Layer 3: Performance Analysis - Real-time Metrics: Sharpe ratio, win rate, max drawdown calculation - Attribution Analysis: Performance contribution by trade type - Pattern Recognition: Profitable vs. unprofitable trading patterns

Core Components Design¶

Trade Tracker Module¶

Purpose: Records and labels every trade in real-time with market context

Key Functions: - Trade Recording: Complete trade data capture with timestamps - Market Context: Market conditions and account state at execution - Real-time Labeling: Instant trade categorization based on rules - PnL Tracking: Continuous profit/loss curve generation

Trade Record Structure:

{
  "trade_id": "trade_12345",
  "account_id": "acc_12345",
  "strategy_id": "momentum_btc_001",
  "timestamp": 1703069415123,
  "symbol": "BTCUSDT",
  "side": "buy",
  "price": 45000.00,
  "volume": 0.1,
  "market_context": {
    "volatility": "high",
    "session": "us_market_open",
    "trend": "uptrend",
    "volume": "above_average"
  },
  "labels": ["trend_following", "momentum", "high_volatility"],
  "pnl_impact": 150.00
}

Performance Metrics Module¶

Purpose: Calculates real-time performance metrics and risk indicators

Key Metrics: - Sharpe Ratio: Risk-adjusted return measurement - Maximum Drawdown: Largest peak-to-trough decline - Win Rate: Percentage of profitable trades - Profit Factor: Gross profit / gross loss ratio - Calmar Ratio: Annual return / maximum drawdown

Real-time Calculation: - Incremental Updates: Metrics update with each new trade - Rolling Windows: Short-term and long-term performance views - Risk Adjustment: Risk-free rate and volatility normalization - Benchmark Comparison: Performance vs. market benchmarks

Attribution Analyzer Module¶

Purpose: Analyzes performance contribution by trade characteristics

Analysis Dimensions: - Trade Type Performance: Trend vs. mean-reversion vs. momentum - Market Condition Impact: Performance in different volatility regimes - Time-based Analysis: Performance by hour, day, market session - Size-based Analysis: Performance by position size categories

Attribution Metrics: - Contribution Analysis: Each trade type's contribution to total PnL - Risk Attribution: Risk contribution by trade characteristics - Alpha Decomposition: Skill vs. market beta performance - Factor Analysis: Performance attribution to market factors

Trade Labeling System¶

Label Categories¶

Behavioral Labels: - trend_following: Trades in direction of established trend - mean_reversion: Trades against trend expecting reversal - momentum: Trades based on recent price momentum - breakout: Trades on price level breakthroughs - scalping: Short-term, small profit trades

Market Environment Labels: - high_volatility: High market volatility periods - low_volatility: Low market volatility periods - market_open: Trading during market opening - market_close: Trading during market closing - news_event: Trading around significant news

Strategy Pattern Labels: - aggressive_entry: Large position size entries - conservative_entry: Small position size entries - quick_exit: Fast profit-taking exits - hold_long: Long-term position holding - stop_loss: Stop-loss triggered exits

Labeling Logic¶

Real-time Label Generation:

def generate_trade_labels(trade_data, market_context):
    labels = []

    # Behavioral analysis
    if trade_data['price'] > market_context['avg_price']:
        labels.append('trend_following')
    else:
        labels.append('mean_reversion')

    # Market environment
    if market_context['volatility'] > threshold:
        labels.append('high_volatility')

    # Strategy pattern
    if trade_data['volume'] > avg_volume * 2:
        labels.append('aggressive_entry')

    return labels
