As much as I hate to spoil everyone's fun, I have to come out and say this RSI/CCI setup effectively repaints.

Take a look at the four pictures below to see what I mean. This is the 1-minute US30 with the RSI/CCI setup as described on the first post of this thread.
Notice the stark difference between the 3rd and the 4th picture with the red vertical line.

I don't know the inner depths of of how MT4 works but either the 5/10/50/55/90/55 lines or the CCI itself dramatically change depending on what is currently in your chart view. The CCI may appear to be in the 5-10 or 90-95 zone at first glance, but then shift towards being somewhere different as price action develops.

In the case of Pictures #3-4, you would have gotten eaten alive by mistakenly thinking price was in a sell zone.

How do I know this?

There's a popular MT4 mobile trading system on YouTube that makes the same mistake. I wasn't able to ascertain who the originator of this idea is, but it's gotten enough traction. People get duped because this glitch is not explicitly revealed in the videos, whether accidentally or intentionally.

Some examples:





I'd be interested to see if anybody else has noticed the same thing.
