What's wrong with this indicator?

A week or so ago I set out to test the Woodie CCI method but was unable to find one that conformed to Woodie's rules. I started with an indicator that was close to correct and created the attached one. As far as I can see, it conforms to spec but does not function correctly - each time a new bar comes in, the last 3 histograms disappear and are never shown again unless the time frame is physically changed in MT4.

I'm quite new to MT4 coding (but not to programming) and would really appreciate some expert help.

Thank you,

Never mind - I found the problem. Some variables that needed to be global were local. Guess I've been programming in Python too long (where one doesn't have to think about such things in the same way)...

Can you attach the version you updated correctly?

here is a good one, in technicolor
