Gernot, my post was a general flow on of the original.
I agree you need something to assess the strength of a move, and if
something works for what & how you trade, then good. I will not disagree
with what you have found to be benefit to you. With my EOD charts, and the
intraday charts I use, I have found my method of plotting a line works for
the stocks I follow. Suggest we have a win-win discussion.

Cheers,
Graham

Graham,

I agree with your assessment of price changes and slopes across many 
different stocks.  However, I daytrade Forex (primarily 5 currency 
pairs) in real-time on 10-min charts.  A degree angle of MAs would 
be very useful to me as a quick indicator of where things are going 
because of the many minitrends, retracements, and consolidations 
throughout a single trading day.
