Roy:
Thanks for your input, I'll give it a try.
One of the big problems with the system tester is that the buy and sell
signals do not correspond closely
enough to the signals given by the equivalent indicator alone.
V7.2 allows you to run a comparison test of several or even all systems in
the same run. I have run a comparison of all systems on a few individual
tickers. I then individually ran the best
one or two systems. The buy and sell arrows mostly do not come close enough
to the correct time, and some give exit signals when the stock is rising and
entry signals when the stock is falling. Am I doing something wrong?
I'd like to be able to set up the systems tester so that the signals closely
correspond to those I get from running the indicator(s) alone. I had
stopped using the system module several years ago as I found it unreliable.
It appears that Equis has not fixed this problem
