Backtrader vs VectorBT vs Pineify: Python Backtesting Compared
Backtrader is an event-driven framework that processes price data one bar at a time. VectorBT is a vectorized engine that runs calculations across entire datasets at once using NumPy and Numba. Pineify converts Pine Script strategies into Python code. Between the three, the choice is straightforward: pick Backtrader if you value readable code and live trading, choose VectorBT if you need raw speed for research, and use Pineify if you already have Pine Script strategies you want to port. I have used all three on real projects, and they serve very different roles.
