My working definition of technical analysis [0]

[0]: https://en.wikipedia.org/wiki/Technical_analysis



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.


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

One thing that I think has real potential is a portable split system aircon for workshops and garages. The all-in-one aircon units have terrible efficiency but split systems require expensive installation that can cost as much as the unit itself. This compromise gets you the best of both worlds.

I built one a year or two ago out of a crusty old second hand split system, and a scrap metal frame that holds the indoor heat exchanger at about head height, and the outdoor heat exchanger back-to-back with it with a ~500mm gap. You open the roller door, position the frame with the outdoor side outside and the indoor side inside, close the roller door, and plug it in. Voila! Aircon! It was way undersized (2.5kW cooling) for my workshop but it still made a noticeable difference. Gonna build a 7kW cooling version for this summer.

I think there's heaps of people with garage workshops that would benefit from something like this. You could also make one where the frame slips through a vertical gap rather than a horizontal one, so it can be set up through a sliding door, allowing renters to use one in houses where the owner refuses to install it.

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.

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.


Technical Analysis isnt a system of predicting the future. Its an analysis of what has happened in the past. You are fundamentally misunderstanding what you're talking about.

Its just a system of interpreting money flows and trends on a graph.
