In light of the recent news that Quantopian is shutting down, I thought it would be interesting to see some actual data on what users here do for backtesting.
I'll go first: I just finished the first working iteration of my own custom backtester in python, from scratch. It was super frustrating at times (a lot of the time), but I'm learning a ton. The feeling of complete control and transparency over how it works is also extremely satisfying.
Edit: obviously nobody is using Quantopian anymore, I meant if that's what you were using
