Hey thank you very much.
Now the system behaves really corectly in generating the buys / sells.
I'm really glad I can perform a kind of intraday back test on my 173 
stocks portofolio in a matter of seconds :)

The only little glitch I noticed is that when it sells on a profit, 
it correctly report a +0.5% profit, but when it sells on a losse, it 
systematically reports a -0.1% instead of -0.50%.

Any clue why ?

Thanks,
