TA is voodoo, it NEVER works reliably. Economics of the process is what actually works.
TA is based on probability, that is based on mathematics, 1s and 0s. The latter has been reliably tested for thousands of years. The former, for only a couple of hundred maybe.
Economics is based on a load suits in a room deciding whey think is best to do with their money, at the detriment of anyone else.
My faith in mathematics is inexplicably higher than any moronic human species based intelligence.
Believe what you want, I know what I'll be putting my money on: 1s and 0s.
TA has almost nothing to do with math, it is mostly interpretation of the prior data with Fibonacci numbers thrown in to give it a 'pseudo'-scientific feel.
However, if it works for you due to some 'hidden' parameter that you don't even realize exist, so be it.
