Method 1: Use default strategy

strategy = create_default_strategy() results = strategy.run_strategy(df) trades = strategy.executed_trades

Method 2: Create custom strategy

custom_strategy = create_custom_strategy( smooth_type="SMA", enable_shorts=False, sl_percent_long=2.5, use_rsi_filter=True ) results = custom_strategy.run_strategy(df)

### Modular Usage

```python
# Use individual components
from models import StrategyParams
from indicators import TechnicalIndicatorCalculator
from signals import SignalGenerator
from trading import TradeSimulator

# Create configuration
params = StrategyParams(smooth_type="EMA", use_rsi_filter=True)

# Use components individually
indicator_calc = TechnicalIndicatorCalculator()
df_with_indicators = indicator_calc.calculate_all_indicators(df, params)

signal_gen = SignalGenerator()
df_with_signals = signal_gen.generate_all_signals(df_with_indicators, params)

trade_sim = TradeSimulator()
final_results = trade_sim.simulate_trades(df_with_signals, params)

🏗️ Architecture & Design Patterns

The codebase follows SOLID principles and clean architecture:

Key Components

• Models: Immutable data classes (StrategyParams, TradeResult)
• Indicators: Technical analysis calculations (RSI, EMA, SMA, ATR, ADX)
• Signals: Trading signal generation logic
• Trading: Trade simulation and execution
• Strategy: Main orchestration and workflow

Design Patterns Applied

• Factory Pattern: MovingAverageFactory for creating MA implementations
• Strategy Pattern: Different moving average types (EMA/SMA)
• Dependency Injection: ADX calculator receives ATR calculator
• Service Layer: Clean separation between calculation, signaling, and simulation
• Immutable Configuration: StrategyParams using frozen dataclasses

SOLID Principles

• Single Responsibility: Each class has one clear purpose
• Open/Closed: Strategy can be extended without modification
• Liskov Substitution: Interfaces can be substituted
• Interface Segregation: Clean, focused interfaces
• Dependency Inversion: Depends on abstractions, not concretions
