That is a much better line, steady increase over almost the whole period. I tried to break it into separate long and short but the result is worse; your version works better as one code going both ways. A couple of big losses in Jan/Feb 2020 but over the long term looks like it could work – génial!

This is another version I had been working on, with a couple of extra filters in the 2h TF to help confirm the primary trend. What do you think? My guess is that yours is probably more stable…
