Nick / Mike -
I stopped by to make a post and was glancing at this. A simple error kind of jumps off the page given your description - that should solve the problem. Your ATC to write MSL is -
AddToComposite( MSL,"~MSL","V", atcFlagDeleteValues |
atcFlagEnableInBacktest); // if i plot this it looks fine
That's fine - odd to write it in the Volume field of ~MSL, but OK. And you said that you verified the data.
You need to read it from the same field in the CBT pass. You had -
MSL = Foreign("~MSL", "X",0);
Check the help file (ALWAYS!) and I don't think you'll find a "X", and its not reading volume.
Hope that helps
