I notice volume inconsistencies in QCharts between the reported total volume figure and adding the volume of 30 min. bars.
For example, right now for CECE I have a total figure of 39030 and when adding the volume of the 30 min. bars I get 23370.
I tend to think the total figure is correct because I find it also with other sources.
Does anyone know what to do to get accurate volume on the 30 min. chart?
Edit: I meant CECE, not DXPE.
