I'm currently working to optimize a function from the research environment to start with; which I am making progress with magic commands or numba decorators; though I think I need to stick to cython. With the final deployment the goal I want something to work in the backtest environment, though I see no examples of this anywhere yet.  Are there any examples of cython for our workflow here?  All my reading is pointing to the need to compile code and see no means of doing this currently.  I may swing back to numba, but I think it may not be sufficient in my case.
