note
that trendlines are normally always detected by peaks and troughs and the
formula is not so intelligent to see which detected peak or trough is important
and which not. Sometimes two peaks are very near on x-axis and than the
formula takes maybe the other one, which is not so
important.

So
from my site a backtest is useless because a real look with the eyes is
always needed.
On
this way such a formula detects sometimes any xy-pattern, while with the correct
peaks/troughs it shows another pattern.

But
there is a software called "Elwave" and as i remember my right, it runs a
lot of scans with different per's for peaks and troughs and detects on thisway
the correct patterns and trendlines.

Re: Backtest with Trendline.dllStephane,Thanks
for the response although I must say that I find it a little disheartening
as I respect you as one of the Guru's of this Forum and if you have not
figured it out then I expect the odds of my doing so have become veryslim
indeed, none the less I will not give up as I am sure you have not
either. It may be that we can't use the trendline.dll but theirmay
be other ways of accomplishing the same end.Many thanks to all the
Guru's in this forum past, present, and futurewdbaker8--- In
