Previous Period Levels — Indicator by JayRogers

previous levels

Description:

It's just levels of previous periods, with the inclusion of 4 hour and and month. Nothing special.

Setup:

Should be mostly self explanatory... but selecting either the 4 hour or month check boxes will override the dropdown selection.
Checking both the 4 hour and month boxes together will cause it to default to whatever has been selected in the dropdown.
