rang3r: A support/resistance indicator with an included cloud.

This indicator finds the minimum and maximum values within a set time period.
Crosses of these minimum and maximum values are noted with the green/red background colours.

The indicator also produces a "cloud", which is generated through the 0.382 and 0.612 points between the two maximum and minimum lines.

Settings:
Entry Period: Time period the indicator checks for min/max points.
Exit Period: Currently Redundant, but may be updated.
Sensitivity: Needed as a leeway for how close a value needs to be to a min/max for it to be considered a cross. I recommend keeping this at default.
