      (right) extremum point with the InpRightExmSide bars on both sides.                                                           

 2) From the first point again "go" to the left and look for the  

     second (left) extremum point with the InpLeftExmSide bars on both sides.

1) From the current bar "go" to the left and look for the second 

   (left) extremum point with the InpLeftExmSide bars on both sides.
