Post From: Historical Market Depth Replay Failing / Download Starting From Today Instead of Historica

Update with new findings (paths and error message):

I kept testing and noticed some extra behavior that may help diagnose the problem:

When I switch from ES to 6E while replaying a past date/time and request depth, a different error appears:
“Historical Depth Data Download Failed. Error downloading historical Market Depth data for 6EZ25_FUT_CME. No market depth data files found. Path: F:\cme_exchange_marketdepth.data\”

I don't have any F: drive at all, so this path does not exist. This makes me think Sierra is referencing an incorrect location for market depth data.

In Global Settings → General Settings → Paths, my Market Depth Data Path is correctly set to:
C:\SierraChart\Data\MarketDepthData\
I have not changed this path recently, and it does not reference F:\ anywhere.

Because of this, it seems that Sierra is getting F:\cme_exchange_marketdepth.data\ from somewhere other than the standard Paths settings. I have only a single Sierra Chart installation on C:\SierraChart.

Could you please:

Confirm whether there are any other configuration files, service settings, or symbol settings that could be forcing Sierra to use F:\cme_exchange_marketdepth.data\ for historical depth, especially for 6E?

Advise how I can clear or correct that reference so all historical depth downloads use my configured path C:\SierraChart\Data\MarketDepthData\ and, if available, the Denali historical depth server?
