Charting of volume TF doesnt work correctly

[SankaCCI]

I have problem with a charting of volume TF. Discreption is in the attach image. Do you explain, where might be a problem. The most problem is that calculation of CCI cant be right.
I have a real tick data from zenfire provider, therefore I ask if the fault is by provider or in the NT.

Thanks for the screenshot SankaCCI - are you looking at 24 hr session data? There seems to be some gaps in your chart, please right click in it and select 'Reload Historical Data'. Then recheck your CCI values at the bottom.
