Starting out at this I always understood that the simplest solution would be best, and that there was absolutely no reason to re-invent the wheel.
I have a couple of moving averages that show what the trend is.
And stochastics to help identify pullbacks.
That's it.
Not rocket science, this !
Market Wizard and Multi-Billionaire Paul Tudor Jones:
PTJ: I teach an undergrad class at the University of Virginia, and I tell my students, “I’m going to save you from going to business school. Here, you’re getting a $100k class, and I’m going to give it to you in two thoughts, okay?
You don’t need to go to business school; you’ve only got to remember two things. The first is, you always want to be with whatever the predominant trend is.
TR: So my next question is, how do you determine the trend?
PFJ: My metric for everything I look at is the 200-day moving average of closing prices. I’ve seen too many things go to zero, stocks and commodities. The whole trick in investing is: “How do I keep from losing everything?” If you use the 200-day moving average rule, then you get out. You play defense, and you get out.
TR: That is considered one of the top three trades of all time, in all history (1987 Crash)! Did your theory about the 200-day moving average alert you to that one?
PTJ: You got it. It had done under the 200-day moving target. At the very top of the crash, I was flat.
TR: What’s the second thought for students?
PTJ: 5:1 (risk /reward). Five to one means I’m risking one dollar to make five. What five to one does is allow you to have a hit ratio of 20%. I can actually be a complete imbecile. I can be wrong 80% of the time, and I’m still not going to lose.

Overcomplication is just a giveaway that someone hasn't grasped what's the wheat, and what's the chaff.
80:20 as everything in life.
