Volume by price info on IB TWS

Hello,

I'm trying to get familiar with IB TWS Demo.
So far so good, but I couldn't find information about traded volume for each price.
Does anyone know on which menu is it?

In case if my question is not clear, I'm attaching a screenshot of this feature from my local broker software.

Thanks

 

look for volume histogram

 

Ah so it's located on chart.
Thank you very much sir.

 

sure..i'm not using it,but i'm pretty sure there is some other variations of it,that could be found in TWS. in a book trader for example.



note that volume is last column on the right. called something like histogram volume

Volume Histogram in chart properties is grayed out for me so I can't enable it. Why is that?

Thanks,
