if I'm going to continue using VSA. I'll need to sort it out in Amibroker.
You may not be aware of it, but there is a version of VSA written for Amibroker. Karthik Marar from www.vpanalysis.blogspot.com wrote it, but the link from that website appears to be dead at the moment. It's available on 4shared.com though. Try http://www.4shared.com/file/QHsclq7a/VPA_V11.htm
I haven't used it myself yet, so let me know how you go with it.
