This indicator will be OBE as soon as the new version of prorealtime will be released (Renko charts will have volumes showing according to the teaser) but it will be still useful for all the traders that don’t want to switch completely to a chart that ignore time. The indicator draws the volume of the exchanged shares for the period depicted by the box.
