CORE FEATURES
================================================================================

✅ Load 20+ trading strategies from CSV, markdown, or Google Drive
✅ Backtest on 10+ years of daily historical data (yfinance free)
✅ Calculate 7 key metrics:
   • Sharpe Ratio (risk-adjusted return)
   • Max Drawdown (worst peak-to-trough %)
   • Win Rate (% profitable trades)
   • Annual Return
   • Total Trades
   • Profit Factor (gross profit / gross loss)
   • Average Trade Return

✅ Walk-forward validation: train 2010-2021, test 2022-2026
✅ Overfitting detection: flag strategies with >30% Sharpe drop (OOS)
✅ Ranked comparison table (CSV + interactive HTML)
✅ Filter strategies: min Sharpe 1.0, max drawdown 35% (configurable)
✅ Pluggable data sources: yfinance → Alpaca → IQFeed (no refactoring)
✅ Extensible architecture: add metrics, visualizations, data sources easily

Performance:
  • 20 strategies, 16-year backtest: 8-10 minutes
  • 20 strategies, 2-year backtest: 2-3 minutes (quick mode)
  • Single process; parallelization-ready (example code included)

================================================================================
QUICK START (3 Steps)
================================================================================

1. Install dependencies:
   pip install -r requirements.txt

2. Verify installation:
   python verify_installation.py

3. Run backtest:
   python backtester.py

Expected output:
  • ranking_report.csv    (spreadsheet with all metrics)
  • ranking_report.html   (interactive dashboard)
  • Console output        (top 10 ranked strategies)

Time: 5-10 minutes for 20 strategies, 2010-2026 data

================================================================================

Modular Design:
  Each component is independent and swappable:
  - Strategy Loader: CSV ↔ Markdown ↔ Google Drive ↔ Custom
  - Data Source: yfinance ↔ Alpaca ↔ IQFeed ↔ Custom API
  - Backtester: backtrader ↔ zipline ↔ VectorBT ↔ Custom
  - Metrics: Add custom KPIs without refactoring core
  - Reporter: CSV ↔ HTML ↔ JSON ↔ Custom format
  - Visualizer: matplotlib ↔ plotly ↔ bokeh ↔ Custom

Key Classes:
  - BacktestRunner: Main orchestrator
  - Strategy: Strategy definition dataclass
  - StrategyLoader: Multi-format loader
  - BacktestResult: Metrics dataclass
  - SimpleStrategy: backtrader integration
  - Visualizer: Charting engine

Data Flow:
  strategies.csv → strategy_loader.py → BacktestRunner
  → yfinance/alpaca → run_backtest() for each strategy
  → BacktestResult → generate_ranking_report() → ranking_report.csv/html

================================================================================
CONFIGURATION OPTIONS
================================================================================

Edit backtester.py → main() function:

Strategy source:
  STRATEGY_FILE = "strategies.csv"           # CSV file path
  # or: "folder_id" for Google Drive

Data source:
  DATA_SOURCE = "yfinance"                   # "yfinance", "alpaca", "iqfeed"
  SYMBOL = "SPY"                             # Ticker symbol

Backtest parameters:
  INITIAL_CASH = 100000                      # Starting portfolio ($)
  commission = 0.001                         # 0.1% per trade

Date ranges:
  train_start = datetime(2010, 1, 1)         # In-sample (train) start
  train_end = datetime(2021, 12, 31)         # In-sample end
  test_start = datetime(2022, 1, 1)          # Out-of-sample (test) start
  test_end = datetime(2026, 3, 9)            # Out-of-sample end

Filters:
  min_sharpe = 1.0                           # Minimum Sharpe ratio
  max_drawdown = 0.35                        # Maximum drawdown (35%)
