Standard Error Channel vs Raff

[Tom Barry <tombarry@xxxxxxx>]

The difference between the Raff Regression Channel and the Std. Error
  Channel can be compared to the trend line approaches outlined
  by Trader Vic and Alexander Elder.
   Trader Vic catches EVERY data point and draws the trend lines through
   the extremes.

   Alex Elder doesn't worry too much about the extreme data points
  ( Which are the difference between the 2 and 3 sigma points).
   Thus , in the Std Error Channel there ARE some points outside the 
  channel.
