Does someone know the links to scientific papers which the Z systems are based on? I'd like to take a look at peer reviewed pro and con discussion before entrusting money to these systems.

Hi Kaga:

I don't think there are scientific peer reviewed papers for most quantitative trading systems. Not 100% sure, but I don't think you will find one for the Z systems. Some of the ideas might be reflected in a paper here or there. The website and manual describe the general principle of the specific Z system.
