🚀 Usage Examples

Using ML Strategies

from forexsmartbot.strategies import get_strategy

# LSTM Strategy
lstm_strategy = get_strategy('LSTM_Strategy', 
    lookback_period=60, 
    sequence_length=20,
    lstm_units=50
)

# SVM Strategy
svm_strategy = get_strategy('SVM_Strategy',
    kernel='rbf',
    C=1.0
)

# Ensemble ML Strategy
ensemble_strategy = get_strategy('Ensemble_ML_Strategy',
    n_estimators=100,
    max_depth=10
)

Using Optimization Tools

from forexsmartbot.optimization import GeneticOptimizer

# Define parameter bounds
param_bounds = {
    'fast_period': (10, 30),
    'slow_period': (40, 80)
}

# Create optimizer
optimizer = GeneticOptimizer(param_bounds, population_size=50, generations=30)

# Optimize
best_params, best_fitness = optimizer.optimize(fitness_function)

Using Strategy Builder

from forexsmartbot.builder import StrategyBuilder, StrategyTemplate, CodeGenerator
from forexsmartbot.builder.strategy_builder import ComponentType

# Use template
builder = StrategyTemplate.get_template("SMA Crossover")

# Or build custom
builder = StrategyBuilder()
sma_id = builder.add_component(ComponentType.INDICATOR, "SMA", {"period": 20})
signal_id = builder.add_component(ComponentType.SIGNAL, "Signal", {})
builder.connect_components(sma_id, signal_id)

# Generate code
generator = CodeGenerator(builder)
code = generator.generate_code()

Using Monitoring

from forexsmartbot.monitoring import StrategyMonitor, PerformanceTracker

# Monitor strategy
monitor = StrategyMonitor()
monitor.register_strategy("MyStrategy")
monitor.record_signal("MyStrategy", execution_time=0.1)

# Track performance
tracker = PerformanceTracker()
tracker.record_trade("MyStrategy", {
    'profit': 100.0,
    'entry_price': 1.1000,
    'exit_price': 1.1100
})
metrics = tracker.calculate_metrics("MyStrategy")

📝 Notes

  • ML strategies require sufficient historical data for training (typically 200+ samples)
  • RL strategies require significant training time (1000+ steps recommended)
  • Transformer strategies are computationally intensive
  • All strategies implement the IStrategy interface for consistency
  • Optimization tools can be resource-intensive for large parameter spaces
  • Marketplace uses local JSON storage (can be extended to database)
