Guy,
thank you for your comments. It is very helpfully for me, if I find my
ideas about trading confirmed by a practical expert, because I'm
coming more from the "theoretical" side, i.e. systems engineering.

I like things to be dynamic. Dynamic systems often are not fully
understood by 100% of the system actors. So there hopefully is room to
identify "imperfections" (e.g. with the aid of a trading system) to
make some money ...B-)...

Do you execute the IN/OUT signals from every single trading system in
parallel or do you add up the different signal to one (weighted)
signal which you use for trading?
Imo, it should be most effective to do the first, if any single system
is specialized to identify a particular profitable pattern.
