Trend Shift Strategy [Fournier-Eaton]

This is a version 0.1 of a revamped Trend Shift Indicator (strategy version).
There are three main components:

• A moving average with color to indicate caution (for those trading short-term)
  
• A series of cross indications above bar to indicate further warning (for those trading mid-term)
  
• Longer term buy and sells informing the trades of the indicator itself. (for those trading longer term)
  

I'd like some suggestions on how to improve this script, please make them in the comments. I do hope this is useful.

Also please see the indicator version of this:
