Investing is about simplifying things to reduce your decisions down to very few...
I developed the GMI Compounding Machine for RV Pro to do just that.
You can adjust how many standard deviations over bought you want to buy and how many standard deviations oversold you want to sell (and you can put in your exact amounts).
What it tells you is how to compound your returns: buy weakness, sell strength but sell less than you buy. It's as simple as that. I know nobody wants to hear it. Everyone wants to trade but really it's not that complicated. All you need to do is decide how cheap or how expensive you want to buy or sell. The rest is just holding and going to the beach.
