This is a modification of Wells Wilder's Parabolic which is
<BR>provided by Omega. You may find it very good for longer
<BR>term trends.
<P>You will be surprised how long you will have to make the
<BR>length parameter to get what you want.
<P>I've included an indicator which you can apply to charts
<BR>and see if it might work. This indicator calls the function
<BR>you would use if you find it works.

have part of the system completed with potentially beneficial results.
However, there are times when false signals occur. I know that creating
a system that is accurate 100% of the time is a bit difficult but am looking
for trend filters that might help reduce the whipsaw losses and non gains
problems. Any suggestions for a trending filter would be greatly appreciated.</FONT></FONT></BLOCKQUOTE>
