@flow Regarding Daniel Rodriguez, the creator of backtrader, I wasn't really here too much at the time he pulled out. But my understanding is, and please any longer term participants correct me if I'm wrong...

Daniel built the great software package, at some point he considered it complete, and I believe he simply wanted to move on to other projects.

As to why he didn't open it up more I don't really know. We have made some efforts to create more ability to at least fix bugs in Backtrader2.
