Several factors lie behind that decision, but the most important is
that it is the easiest/fastest way for me to do things. I agree that
everything could be done in R, but it would take a huge amount of
effort for _me_ to get there. I did start on an R package for all the
important technical indicators and some classic systems, but my
progress was too slow to allow me to do anything important in the time
I had available. For example I ran into problems involving the details
of S3 and S4 classes which seemed very hard to solve and the package
its, which I relied on, was orphaned. As I already had these things
coded, debugged and working in Python, I just didn't have the
time/will to recode everything. The bottom line is I can code systems
very quickly in Python and relying on R for analytics rather than
coding the stats myself makes perfect sense to me.
