Thanks jcl.

Perhaps this would be a good addition to the manual?

Something like: When implementing or updating and Test using your own Broker's AssetFix.csv data gives a very different result from what's posted in the manual (and not Z1, Z2 or Z12), then one should look for the Asset(s) causing the variation, exclude it/them, reTest, and copy the .dbl file to the Trading system...

Thanks.
