Requesting Range Bars + Volume Profile / Delta Profile Discussion

I would like to request Range Bars as a chart option. They are very useful for analyzing pure price movement without the time factor.

Also, it would be great to discuss how the current Volume Profile and Delta Profile data is calculated.

Is it based on tick volume or true exchange volume? How accurate do users find it for futures markets?

For traders using POC, VAH/VAL, volume nodes, and order flow analysis, the quality of volume data can make a big difference. Would like to hear the community’s thoughts and experience.
