The correct website is:
http://www.callnetuk.com/home/tradingsystems/
I tested one of the systems called PDS on daily bars of S&P futures to try
and duplicate the equity chart on the web page and was able to do so with:
Close positions at end of day
% Trailing Stop = 50% with a $1000 floor (as noted by John)
I suspected that the great performance was due to the known behavior of
TradeStation that assumes an intraday price sequence on the price of bars
which makes "% Trailing Stops" give misleading results so to test this, I
reversed the buys and sells of the system.
And magically, the profits were almost the same!
I was referred to this site a couple of weeks ago from a post on some list
and after searching the site carefully, I was finally able to find a way to
send them an email message to ask some questions.
I got a one-line reply to my first question. This prompted me to ask if the
system took advantage of the known faulty behavior of TradeStation.
There was no reply. (Copies of emails are attached.)
Needless to say I would be very careful about trading this one...
