Well there's the rub isn't it. A noob has preconceived compulsions that they look for affirmation, to convince their resolve to execute a trade. A pro is much more thoughtful, considered and precise. Most of us here though, I think nowadays conjoin FA and TA to inform our decisions and we each have a unique background strategy pointing us in a certain direction.
It depends a lot on whether you bought or are buying an asset that pays you regularly ad infinitum and it's irrelevant what the market thinks the asset is worth right now, or, you bought the asset because you think someone else in the market will pay a higher price for it sometime, it's just when the 'sometime' is right.
Either way, TA is an essential tool for any investor who wants insights into live or delayed market price sentiment, literally down to the minute if you want to.
There is no trader especially, who would not be using TA to inform their decisions.
Some income/value investors use TA to time their conviction to buy, or buy more of their earners.
