I think you've missed the point about TA. To use TA is to employ back tested trading methods (based on trends, divergences, etc). To say your system is "back tested" and therefore superior just means you are employing a different method of TA.
Nope, I've got it. I didn't say anything about my strategy being back tested. My strategy has been forward tested, and the results are posted. That events into a historical graph, but that's not a back test. Those are real results.
Back-testing using TA comes with serious data-snooping flaws.
I am fully aware that there are people who believe whole-heartedly in TA.
I prefer the true forward test of time. We can reference bitcoin, but we can also reference history in the stock market. TA, by far, consists mostly of pure losers. It's not an opinion.
It is simply fact. There are a handful of TA people who have shown long track records of success. A true statistician can inform you that this is also with statistical certainty to occur for some.
Maybe, just maybe, this 5-10% of successful TA people are really just plain good at what they do. Still, chances are, by far, it's not you. I know people take great offense to that, but it's just plain fact.
Even me and my "successful" strategy, in the grand scheme of things can be utter crap. Most likely it is. Again, just a fact.
