Mean Reversion Channel - (fareid's MRI Variant)

Description :
Mean Reversion Channel objective, based on Mean Reversion theory ( everything has a tendency to revert back to its mean), is to help visualizing:
Inner Channel -> Dynamic Support and Resistance
Outer Channel -> Overbought/Oversold Zone which may signal consolidation phase or potential reversal due to unsustainable move

Details on some of the filtering type used for mean calculation can be read in Ehlers Technical Papers: "Swiss Army Knife Indicator" and/or his book "Cybernetics Analysis for Stock and Futures"

Disclaimer:
These study scripts was built only to test/visualize an idea to see its viability and if it can be used to optimize existing strategy.
Any ideas to further improve this indicator are welcome :)

- User able to select HTF type (Auto or Custom)
- For Auto HTF, the script will automatically recommend HTF to be scanned
- For Custom HTF, the script will scan the user defined HTF based on the user input screen
- The MTF will also calculate the distance of last traded price from each TF's Mean, displayed as % of last traded price.

2) Display Mode
- Now user able to display/hide the channel
- HTF Status Label available in 2 display mode (Always Display / On Hover)
- For Always Display Mode, the HTF will always be displayed
