//| You can use this indicator to measure when the EMA angle is      |
//| "near zero". AngleTreshold determines when the angle for the     |
//| EMA is "about zero": This is when the value is between           |
//| [-AngleTreshold, AngleTreshold] (or when the histogram is red).  |
//|   EMAPeriod: EMA period                                          |
//|   AngleTreshold: The angle value is "about zero" when it is      |
//|     between the values [-AngleTreshold, AngleTreshold].          |      
//|   StartEMAShift: The starting point to calculate the             |   
//|     angle. This is a shift value to the left from the            |
//|     observation point. Should be StartEMAShift > EndEMAShift.    | 
//|   EndEMAShift: The ending point to calculate the               |
//|     angle. This is a shift value to the left from the            | 
//|     observation point. Should be StartEMAShift > EndEMAShift.    |
