Thanks all!

@jcl:
Thanks for the clarification. Is this in the manual somewhere? Sorry if I missed it.

Followups:
Do I understand correctly that there is therefore no way to verify the results produced by the Train? I.e., what Trade results would be expected using the new Z3.par and my Broker's values?

My AssetsFix.csv came from the Download script without any changes - are Roll values still suspect in that case?

@MatPed:
Agreed. The Z Systems have yet to completely satisfy my Proof-Of_Concept perspective. But (aside from Z5 ) they haven't completely crashed and burned yet either...

How long have you been on Oanda? Has it been an OK/good experience?

Thanks again all.
