VectorBT

VectorBT is a Python library designed for vectorized backtesting and analysis. It is optimized for speed and scalability, particularly with large datasets, by leveraging NumPy and Numba for parallel processing. The library supports testing thousands of configurations simultaneously, offering faster backtesting for extensive datasets and complex parameter sweeps. While it excels in backtesting speed and analysis, it does not natively support live trading or offer extensive control over order execution and broker integration.
