Hello Dimitris,
A little modification from Tomasz original code and 'kitakste edho'
(excuse my lousy Greek ;)
Regards,
Peter

Wally,
You may go to
http://groups.yahoo.com/group/amibroker/message/38370
http://groups.yahoo.com/group/amibroker/message/38424
for the two alternatives.[I hope enough explained].
I try to introduce variable smoothing to an already useful trend
detector, the DEMA(StochD(40),20).
It has nothing to do with PSAR, it is a stand-alone indicator.
Since it is quite smooth, I use 3-bars peak to signal the change of
the direction.
DT
PS. We will follow a similar procedure, when PSAR will accept
variable parameters, to improove PSAR results.
