So my questions is, are there functions within basic python libaries(such as pandas, numpy, matplotlib) to backtest without using backtesting liabries(such as pyalgotrade, backtesting.py and zipline). So could you backtest by just using basic libraries or do you have to use the backtesting liabries if you already had the historical data? Thanks

There is no magic in programming. If a library implements it, you can do it as well.

The question is whether it is worth the amount of effort to re-do someone else's efforts, and whether you can do it better or not.

  • Do you think it is easier to just use what they give you, or to backtest on your own and then be able to create your own functions and peramaters? – benito.cano Apr 26 '20 at 21:31
  • @benito.cano Who is they? I don't know about your needs, wants, skills, etc, you'll have to decide for yourself. – orlp Apr 26 '20 at 21:58
