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: Support Board Posting Information: Providing Chartbook with Only a Single Chart 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. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

The date of the replay (ES Continuous Contract) where I noticed the issue was 12/11/25. It begins around 9:47:50 eastern time and I noticed it happen several times over the next 6 minutes (specially between 9:49-9:51). You can see the Buy and Sell columns freeze.

We are not able to reproduce this with your chartbook. Everything is working properly and there is no pausing. Is the only issue you see with the Market Depth data? Does the Clock continue to update and the prices? For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Yes, the Clock and everything else freezes. The clock reaches 9:47:51, then freeze, and it restarts at 9:47:54. It's more noticeable on my full chartbook since there are more charts with the Vol by Price and Vol by price for TPO studies. After I remove those studies, everything works great.
