A second label can be created dependent on current days RVOL %. If RVOL is not 0 or 1, then it will create the second label. Otherwise it will just leave it as the standard label.
The calculation for second label is RVOL * ATR.
There is also possibility to put in custom ATR (i.e 1.5 x ATR, or 2 x ATR) by adjusting the RVOL details.
There is some code to start calculating RVOL, and then adjusting ATR based on RVOL, although that is not complete.
