Why VectorAlpha TA Library?

Blazing Fast

CUDA kernels and AVX-512 SIMD instructions deliver 30-50x speedups. Process millions of candles in milliseconds.

Complete Coverage

300+ indicators from basic moving averages to advanced patterns. Full compatibility with existing TA-Lib code.

QA

Battle Tested

97% test coverage with validation against reference implementations. Used in production by quantitative traders.

Technical Architecture

How It Works

  • • CUDA kernels for parallel indicator computation across GPU cores
  • • AVX-512 SIMD fallback for CPU execution with vectorized operations
  • • Zero-copy memory management with pinned host memory
  • • Batch processing engine for multi-symbol analysis

System Requirements

GPU (Optional): NVIDIA GPU with CUDA 11.0+ for maximum performance
CPU Fallback: AVX2 or AVX-512 for 10-15x speedup without GPU
Languages: Rust, Python, JavaScript, C/C++ bindings
Drop-in: Compatible with TA-Lib API - no code changes needed
