My working definition of technical analysis [0]

It is always fun (in a broad sense of that word) when I make a comment on an industry I know nothing about and somehow stumble onto a thing that not only has a name but also research. I am sure there is a German word for that feel of discovering something that countless others have already discovered.

  • XKCD calls it the "Lucky 10,000" [0]

    • That is referring to something completely else. This is referring to some common fact that the person didn't figure out by themself. OP is referring to something they came up with themselves in a field they have no experience with, realizing it is actually a thing in a way feeling validated and clever.

  • Any time I invent a cool thing, I go and try and find it online. Usually it's already an established product, which totally validates my feeling that the thing I invented is cool and would be a good product. :D

    Occasionally it's (as far as I can tell) a legitimately new 'wow that's obvious' style thing and I consider prototyping it. :)

    • What have you prototyped recently? Anything you have released to market? I'm in the same general area by am teetering on actually launching products wouldn't mind connecting with a like minded e gineer

I am frankly astonished at the number of otherwise-intelligent people who actually seem to believe in this stuff.

One of the worst possible things to do in a competitive market is to trade by some publicly-available formulaic strategy. It’s like announcing your rock-paper-scissors move to your opponent in advance.

  • Technical analysis is a basket of heuristics. Support / resistance / breakout (especially around whole numbers) seems to reflect persistent behavior rooted in human psychology. Look at the heavy buying at the $30 mark here, putting a floor under silver: https://finviz.com/futures_charts.ashx?p=d&t=SI This is a common pattern it can be useful to know.

  • A couple of subtleties in that. Rather than rock paper scissors with three options, there are hundreds of technical strategies out there so you may still be doing something unusual. Secondly the mass of the public are kind of following a technical strategy of just buy index funds because the index has gone up the past. Which is ignoring the fundamental issue of whether stocks decent value for money at the moment.
