Adaptive Moving Average with ATR bands

This is script is essentially "AMA" and was originally developed by Alex Everget , I just added half ATR as a band to AMA to reduce the false breakouts and
use it to confirm hidden divergence with it.

リリースノート:

Just added an input from user to use it for Stop loss.
basically x*ATR is going to be used for stop loss.
you have to add/subtract it from closing price yourself.

リリースノート:

The previews version ruined the scale and actually plotted the stop loss line which was not intended to do that.
