Jose,
How do you build a sound trading strategy without
testing an idea for soundness? This is where computers really shine?! I can run
several different tests in minutes!
Of course if the tests are bogus, what is the
point.
Thanks again Jose, Scott

Look for in a System Test
Scott, it seems that you are attempting to develop a
profitable
trading system with the aid of a bunch of indicators thrown
into the
System Tester pot. You are unlikely to develop a sound
trading
strategy just by analyzing system tester results.
Note that
the System Tester has been named thus, to test systems.
Otherwise it
might have been named "System Developer".
My humble advice is to forget
the System Tester for the time being,
and concentrate on developing a
sound trading strategy. Once this is
in place, by all means test it
in the System Tester or preferably
TradeSim. Don't forget to include
transaction costs (brokerage/
spread/slippage).

better than 50/50 but have yet to stumble on anything that yields more
winners than losers.
