I'm looking at Lean as a possible home backtesting framework. From the framework I've seen, they fall into 2 categories - either they use pandas/numpy (and associated libraries) or they code everything themselves. I come from a Matlab background and at the moment I use pandas/numpy for backtesting.

From what I can see Lean falls into the second category. Is it possible however, to use pandas/numpy etc. when writing backtests in python? Do you have any examples?
