Why VectorAlpha Backtester?

GPU optimized backtesting

GPU Optimized

VRAM-resident execution with zero-copy optimization. Process millions of parameter combinations in seconds.

Robust strategy validation

Robust Validation

Monte Carlo analysis and cross-fit validation ensure your strategies aren't overfitted to historical data.

Desktop native backtesting app

Desktop Native

Rust + Tauri desktop app with native performance. Your data never leaves your machine.

Technical Architecture

How It Works

  • VRAM-resident execution keeps data on GPU for zero-copy operations
  • Parallel kernels test thousands of parameter combinations simultaneously
  • Monte Carlo engine runs 10K+ simulations for robustness testing
  • Genetic optimizer intelligently searches parameter space

System Requirements

GPU (Recommended): NVIDIA GPU with 8GB+ VRAM for best performance
CPU Fallback: Multi-threaded CPU mode with SIMD optimizations
Platform: Desktop app for Windows, macOS, Linux (Rust + Tauri)
Privacy: 100% local - your data never leaves your machine
