MTF CCI indicator small modification help!

Hello,

I see MTF CCI+BB can be a simple and profitable scalping strategy as Forexcube does. I want to have three CCIs displayed on my chart: current timeframe + one level higher timeframe + two level higher timeframe. (For example, if currently I am at 5M chart, I want to see CCI 5M+15M+1H). Then if I shift the timeframe to 15M, my chart should display CCI 15M+1H+4H automatically. The following code works but it is designed to manually input fixed timeframe, instead of automatic timeframe shifting. I want it to be automatic because I often shift my timeframes for MTF analysis. Although I have not virtually any knowledge of coding, I think it wouldn't be that much difficult. Please make this modification and let's share with everyone. Or, if someone knows similar indicator available already, kindly let me know. Thank you very much in advance.

Final display would look like this: (In this picture, 5M (current TF), 15M and 1H CCIs are displayed)

Delete the "extern int TimeFrame=0;" line.
In the init above the swich operator add: "int TimeFrame=Period();"
