2.3.1 Backtesting

The Backtesting component simulates trading with historical data and evaluates the performance of user-defined strategies. This component should be implemented using libraries like Backtrader, PyAlgoTrade, or Zipline.

  • Class: BacktestingEngine
    • Methods:
      • run_backtest(strategy, data): Executes the backtesting process using the provided strategy and historical data.
      • get_trade_logs(): Retrieves the trade logs generated during the backtesting process.
      • get_performance_metrics(): Calculates and returns the performance metrics for the backtested strategy.

2.4 Strategy Optimization and Deep Learning

2.4.1 Deep Learning

The Deep Learning component implements deep learning models using PyTorch for strategy optimization.

  • Class: DeepLearningOptimizer
    • Methods:
      • train_model(strategy, data): Trains a deep learning model on the given strategy and data.
      • optimize_strategy(strategy): Applies the trained model to the strategy, returning an optimized version of the strategy.

2.4.2 CUDA Support

The platform should enable GPU acceleration with CUDA for high-performance model training.

  • Module: cuda_support
    • Functions:
      • initialize_cuda(): Initializes the CUDA environment and verifies compatibility with the user's system.
      • check_cuda_availability(): Checks if CUDA is available and supported on the user's system.

2.4.3 Optimization Algorithms

The platform should apply optimization algorithms like grid search or Bayesian optimization to fine-tune strategies.

  • Class: StrategyOptimizer
    • Methods:
      • grid_search(strategy, parameter_grid): Applies a grid search algorithm to optimize the strategy based on the provided parameter grid.
      • bayesian_optimization(strategy, parameter_bounds): Applies a Bayesian optimization algorithm to optimize the strategy based on the provided parameter bounds.
