I'm very new to Backtrader and the community, but I have to echo the comments made here. After having worked with various other python & non-python trading platforms, I was blown away when I stumbled upon Backtrader and the depth of its capabilities. It's incredible and you should be very proud!
It would be an absolute shame to see the project wither and splinter into various forks.
Please continue to support the project. If you do want to take some time off, then please consider inviting a few others into the project as collaborators.
