Center of Gravity - extended - indicator for MetaTrader 5

Theory:

The original (to the letter as described) version of Center of Gravity was published here : Center of Gravity - Ehlers. But, as described there, the original lacks what we could use as "significant level(s)" (not even zero can be used on the original version).

This version:

In this version a correction in the calculation is added that allows us to have the zero level as a "significant level". Due to that change, 3 color change methods are added in the options:

• color change on signal / trigger line cross (the default)
  
• color change on level zero cross
  
• color change on slope change
  

Usage:

Depending on the way you desire to use it (by setting the color change method) you can use that color change as a signal.
