The VROC indicator rises when the current volume surpasses what it was previously and the VROC indicator is in a decline when the current volume is lower than what it previously was.

This is to say that the VROC indicator spots volume increase that are cited at important peaks or troughs and also during breakouts.

The VROC indicator employs an easy calculation in which the volume of the previous specified periods minus the volume of the current bar, divided by volume n bars ago and multiplied by 100.

The trading indicator comes with a default “PeriodROC” value of 25 and this can be tweaked. For short term outlook, distinctive values should be between 10 -15 bars.

The problem with this value is that sudden peaks are created as a result of sudden price change.

Long term outlook such as those of daily, weekly or monthly time frames should adopt a “PeriodROC” value of 20 and above.

For a more realistic view, I’ll employ chartist to use a 25 – 30 day period; this is because this length of time allows the chart display a smoother and a more rounded view.

Altering the values of the “PeriodROC” in the indicator’s parameter setting can alter the indicator’s sensitivity.
