Bill,
I used to use Raff Regression channels and now use Standard
Deviation channels with the deviation set at two for my short term
channels. I still prefer to use channels constructed with Trader Vic
trend line philosophy after there is enough data for two good
reactions. In testing, both Raff and Standard Deviation channels seem
to work about equally well but the problem is knowing when to set the
beginning and end of the channel. I've found that for short term up
trends, starting a Standard Deviation channel at the low and ending it
at the highest high and extending it to the right will hold most good
moves and get you out before a bad reaction sets in. That doesn't
work as well with Raff Regression, although Raff Regression channels
with the starts and ends above the lows and below the highs will work
as well. The problem is that I can't quantify exactly where to place
the start and end points, so I now use the Standard Deviation channels
instead. Having said that, If you could find a consistent methodology
for placing Raff Regression start and end points they should work as
well.
I haven't played with the standard error channels, but you can
probably find a method using them that will work as well. There are
many methods that work. The secret is finding one you understand that
you are comfortable with and can stick to.
Jim
