Rather more seems to be a work in progress.
All credit to the OP for determined, verging on obstinate, perseverance.
Having been down this kind of road in my early years, I realised that "good enough" was, well, good enough.
I suggest that Pareto rule is invoked here.
I suspect the first 2-6 (20%) indicators of his 31 provide 80% of his edge.
The rest are giving a diminishing return.
By no means am I the finished article vis-a-vis trading, so by all means trash my opinion, but simply accepting a workable edge is sufficient to propel an account into the black.
Looking for the Holy Grail can still be pursued alongside real-world trading the less than Holy Grail.
