Periodic chart freezing in v2849 when using Volume by Price

I am experiencing replay freezes in version 2849 that do not occur in version 2695.

Symptoms:

1. Replay freezes at the exact same timestamp every time

2. CPU usage remains normal (no spike)

3. Rewinding and replaying freezes at the same point

4. Safe Mode does not change the behavior


What I’ve confirmed:

1. The issue is not related to ACSIL or custom studies

2. A simple chartbook without Volume by Price works correctly

3. Copying charts into a new chartbook does not resolve the issue

4. Deleting and downloading chart data and depth data had no affect.

5. Removing Volume by Price and Volume by Price for TPO from all charts eliminates the freeze



How Volume by Price is configured:

1. The Vol by Price studies all use 'Trading Day Start Time to End - Reset at Day Session'

2. Separate profiles for RTH and Overnight sessions

3. No Visible Range profiles


Replay Mode:

- Standard Replay
- All Charts in Chartbook


This appears to be a blocking condition where Volume by Price calculations are waiting for data to complete during replay in v28xx.

Could you please confirm:

Whether replay behavior regarding Volume by Price aggregation changed in recent versions

What specific Volume by Price settings are recommended to avoid blocking during replay while keeping session-based profiles enabled

Thank you.

No, there have been no changes at all:
Whether replay behavior regarding Volume by Price aggregation changed in recent versions

Provide us the Chartbook, and let us know the date and time and time zone where you noticed this and we will test. Instructions:

When you say freeze, do you mean the replay just does not advance, or the user interface of Sierra Chart, is nonresponsive? If the replay is not advancing, this is completely unrelated to the Volume by Price study.
