Advanced Features Guide

Portfolio Optimization Engine

The Portfolio Optimization Engine implements Modern Portfolio Theory to help optimize portfolio allocations.

Key Features:

Usage:

  1. Navigate to Tab 10 (Portfolio Optimization) in PowerTrader Hub
  2. Load portfolio data (CSV format with columns: security, weight, return, sector)
  3. Configure optimization parameters:
    • Risk tolerance level
    • Optimization method (Sharpe ratio, minimum variance, etc.)
    • Constraints (sector limits, individual security limits)
  4. Run optimization to get:
    • Optimal weights
    • Expected return and volatility
    • Sharpe ratio
    • Efficient frontier visualization

Data Format:

security,weight,return,sector
AAPL,0.30,0.15,Technology
MSFT,0.20,0.12,Technology
GOOGL,0.15,0.18,Technology
JPM,0.15,0.08,Financials
XOM,0.10,0.06,Energy
BRK.B,0.10,0.09,Financials

Backtesting Framework

The Backtesting Framework allows comprehensive strategy testing and optimization.

Key Features:

Usage:

  1. Navigate to Tab 11 (Backtesting) in PowerTrader Hub
  2. Load market data (CSV with OHLCV format)
  3. Select or configure trading strategy:
    • Moving Average Crossover
    • RSI Strategy
    • Custom strategy implementation
  4. Set backtesting parameters:
    • Initial capital
    • Commission rates
    • Position sizing
  5. Run backtest to get:
    • Total return
    • Sharpe ratio
    • Maximum drawdown
    • Win/loss ratio
    • Equity curve

Market Data Format:

date,open,high,low,close,volume
2024-01-01,100.0,102.0,99.5,101.5,1000000
2024-01-02,101.5,103.0,101.0,102.8,1200000

Strategy Development: Create custom strategies by inheriting from TradingStrategy:

from backtesting_engine import TradingStrategy, PositionType

class CustomStrategy(TradingStrategy):
    def __init__(self, param1=10, param2=20):
        super().__init__()
        self.param1 = param1
        self.param2 = param2

    def generate_signals(self, data):
        # Implement signal logic
        signals = pd.Series(index=data.index, dtype=int)
        # Your signal logic here
        return signals

Performance Attribution Engine

The Performance Attribution Engine provides detailed analysis of portfolio performance drivers.

Key Features:

Usage:

  1. Navigate to Tab 12 (Performance Attribution) in PowerTrader Hub
  2. Load portfolio and benchmark data
  3. Configure attribution analysis:
    • Attribution method (Brinson-Hood-Beebower, etc.)
    • Time period for analysis
    • Factor models to use
  4. Run attribution to get:
    • Total attribution
    • Allocation effects
    • Selection effects
    • Factor exposures
    • Risk decomposition

Attribution Methods:

Graceful Degradation

PowerTrader is designed to work gracefully even without optional dependencies:

API Reference

Portfolio Optimization

from portfolio_optimizer import PortfolioOptimizer

optimizer = PortfolioOptimizer()

# Optimize portfolio
result = optimizer.optimize_portfolio(price_data)

# Calculate efficient frontier
frontier = optimizer.calculate_efficient_frontier(price_data)

# Get rebalancing suggestions
rebalance = optimizer.suggest_rebalancing(price_data, current_weights)

Backtesting

from backtesting_engine import BacktestEngine, MovingAverageCrossStrategy

engine = BacktestEngine()
strategy = MovingAverageCrossStrategy(short_window=10, long_window=20)

# Run backtest
result = engine.run_backtest(market_data, strategy)

# Monte Carlo simulation
mc_result = engine.monte_carlo_simulation(market_data, strategy, num_simulations=1000)

Performance Attribution

from performance_attribution import (
    PerformanceAttributionEngine,
    create_sample_portfolio,
    create_sample_benchmark
)

engine = PerformanceAttributionEngine()
portfolio = create_sample_portfolio()
benchmark = create_sample_benchmark()

# Brinson attribution
result = engine.brinson_attribution(portfolio, benchmark)

# Factor attribution
factor_result = engine.factor_attribution(portfolio, factor_data)
