Based on Normalized Smoothed by Dreadblitz
Updated slightly the rules about when it'll take a signal, and made it an overlay so that you see "green" and "red" on the price bar.
Things you might want to do when using it.
- Add a stoploss/trailing stop probably a MA of your choosing.
- Check different time frames to confirm a strong entry
