Thanks @jcl.

A couple of follow-ups:

- I can certainly understand not spending time on something that doesn't matter! laugh But in that same vein, why not just use 0? Is there a reason Spread=0.1 is preferred over Spread=0?

- Spread 0.1 (or 0) makes no difference for Z8, Z9 because they trade so infrequently? And the same idea would apply to any strategy with a "BarPeriod" of month(s)? Week(s)?

Thanks.
