Does anyone know of charting service that provides volume bars/indicator like this?

I looked at Think or swim, Ninja and Market delta, they are close, but not what I am specifically looking for .


Thank you

 

What is buy and sell quantity? Is it activity at best bid/best ask or something else?

 

# of contracts bought( green)/ sold ( red) in the volume bar

 

good idea!
Thanks

 

Blue volume at the ASK, Red volume at the Bid. Out line Total Volume.

 

It will be interesting pic for constant volume bars...!!!!

 

ensign software

 

I agree.
Not too visually distracting but useful information.

 

That kills it.

 

in sierrachart you can load bid vol and ask vol on to the same panel, you can vary the bar size and change their display order, works for any type of charts.
