Quote from logic_man:
Why do I insist on this? Because for me TA "can be" (not that everyone would actually implement it this way, but I implement it this way) a form of algorithmic trading. Algorithms are, by definition, objective and programmable.
What I don't understand is how you can, on the one hand, defend and praise HFT, which is also (primarily?) algorithmic trading and deride TA, which definitely has overlaps with algorithmic trading, even if not everyone's variation of TA is algorithmic.
Then, there is the contradiction of you saying that "fixed systems" are obsolete, yet HFT, which you seem to like, is almost all "fixed systems", since you don't have time to be deciding among various options when your execution times are that fast. There is probably a good deal of "branching logic" in HFT algorithms, but even with branching, they are "fixed systems".
I'll accept my role here as an educator -- HFT is not a trading method but rather encompasses multiple strategies-- primarily market making and latency arbitrage. It is constantly evolving and in no way "fixed". One HFT strategy may work for a week then it's edge is gone and another strategy is implemented. HFT has nothing to do with TA for the most part.
