Hi again,
 
Just for reference:
"super winning" system :-))) is:
 
buy = sell = 1; / * buy sell everyday 
*/
 
Settings: Long only. buy on low, sell on 
high
 
Test on any market to get tremendous 
returns.
 
This is just for showing how important is 
to use REALISTIC settings.

Dimitris,
 
The reason why you get so good results is the 
one
I mentioned already sometime ago:
you set unrealistic entry/exit settings- buy on 
day's low
and sell on day's high. 
 
To prove it: p<FONT face=Tahoma 
size=2>lease modify your selling formula to:
 
sell = buy; /* sell on the same bar as you buy 
*/
 
and your system will be winning no 
matter
what is a buy formula with buying day low and 
selling day's high!
 
You can go further buy on low and sell on high 
everyday -  
This "system" generates 45272.59 % during 281 
days on DJIA stocks
without ANY optimization.
 
Great ? Not really - it is just an effect of 
unrealistic settings.

I wrote yesterday that this system is 
strange.
One behavior never met before is the 
following:
I scan with the exposed buy/sell 
conditions
Buy=Cross<FONT 
color=#000000>(C2,C1);Sell=Cross<FONT 
color=#000000>(C1,C2);
The best % Net profit was +391% andall the 
120 combinations
from optimization were profitable.
Then I inverse buy/sell with sell/buy, 
ie
Sell=Cross<FONT 
color=#000000>(C2,C1);Buy=Cross<FONT 
color=#000000>(C1,C2);
The best % net profit was 88.4% (!!) and the 
half of the 120 combinations
were profitable, if for a period 
of
two years you were making mistakes all the 
time (32 trades).
It is not easy to explain this 
property.
