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).

problem with this is that with the exits being what they are, my 
losses are humongous. I have been trying to find a system that is 
better than 50/50 but have yet to stumble on anything that yields more 
winners than losers.
