Brainstorm for an ultimate trading system

Hello! I'm Thierry HUITEL, (from France, sorry for the mistakes in my 
text). I joined your community a few days ago, because I got 
amibroker. What strikes me is the quality of the posts here. Tomasz 
Janeczko, David Holzgrefe and many others share their knowledge and 
that is great.
I'm used to metastock, but what I find great with amibroker is the 
very fast automatic analysis.

With such a tool, such minds and cooperation, I thing it's possible 
to build a very efficient trading system, if you're interrested.

To begin the debate, I would like to give you my thoughts:
1. Common trading systems are often disconnected from the global 
index (^IXIC and so on), that's wrong.
2. the real trading costs and delays must be taken into account. (I 
mean, not a trade every 2 hours)
3. It's not useful to look for a system that finds every buy and sell 
opportunity for every stock, because a powerful tool like amibroker 
can quickly scan the whole nasdaq.
4. IMHO, the first and best thing to find is an ultimate buy trigger, 
the one that is a conjunction of several bullish signs that confirm 
each other. 

for instance that formula rejects a lot of stocks, but is efficient 
more than 70% of the time:

monrsi = rsi( 14 );
un = cross( monrsi, 30 ) AND (EMA( ROC( MA( C, 22 ), 250 ), 150 ) / 
100) < 0;
deux = cross( macd(), signal() );
buy = un AND deux ;
sell = Cross(70,RSI(14)) AND Cross (ma(close, 14), 
close);_______________________________________________________________
