As pointed out in the manual, US residents are hamstrung by reduced assets, leverage, etc., to the extent that returns can not only be reduced, but in some cases profitable systems can become losers.

Searching in the manual & forum didn't provide much more insight, so wondering if someone has "been there, done that" and evaluated the Z Systems in this context? I'm interested in this from both the specific & general points of view. For US residents & their legally-limited capabilities:

- Is any Z System (or a few) clearly better than the others?

- More generally, is any algorithm (or a few) more likely to result in a profitable system?

Thanks.
