This is an update on my previous script. After a lot of testing, I've come to the conclusion that "less is more". Look at the code and you will see that I've double slashed (//) a lot of barcolor code. The chart was just too messy. The simplification is an improvement on the idea. This is not a 'system" or strategy, but yet a suggestion to take a closer look. Bars are colored when the price closes below the lower band and moves above it, and when price closes above the upper band and moves below it. Don't forget good risk management and position sizing with any strategy/system you use. I've also included Lazybear's MACDL and repo32's Buy/Sell EMA
to the chart.
