blau's ci

[lucid78]

i found an old thread at http://forum.esignalcentral.com/show...light=blaus+ci but the problem with the script was that it didn't reload with each bar but had to manually be reloaded. chris at www.sr-analyst.com was kind enough to fix it and i'm posting the corrected script here.
