Issue: Historical Market Depth data backfill for NQM26-CME consistently returns "The type of error was unspecified" for all attempted dates. Live depth recording works correctly. Issue is isolated to historical depth backfill service. Affected dates verified: 2026-04-23, 2026-04-24 (and others tested before). 8+ HD Requests over 5 days, multiple servers (ds26, ds28, ds32) — same result. Settings verified: - Global Settings >> Sierra Chart Server Settings: Support Downloading Historical Market Depth Data = Yes Maximum Historical Market Depth Days to Download = 0 - Global Settings >> Symbol Settings: Use Custom Symbol Settings Values = checked Selected: NQ?##-CME (template covering NQM26) Only custom override: Record Market Depth Data = yes Service routing fields (all correct, not custom): Historical Intraday Data Source = exchange data service SC Data Service Code = cme Real-Time Data Client = SC exchange data service sub-client 4 Steps already performed (all on 2026-04-27 / 2026-04-28): 1. Right-click on chart bar >> Download Depth Data from Date-Time: 8+ attempts, all return "Type unspecified", 0 records. 2. Use Number of Days to Load >> Market Depth = 7 + Reload: no effect. 3. Update From Server (Global Settings >> Symbol Settings): "Symbol settings received" confirmed in Message Log, followed by Reconnect (File >> Disconnect / Connect to Data Feed). HD Request 135/141/142 after Update — same "Type unspecified". 4. Disable Use Custom Symbol Settings Values + Reconnect: no effect. 5. Re-enable Use Custom + Reconnect + retry on 2026-04-23: HD Request 147 — "Type unspecified" for 2026-04-23 as well. 6. Send For Analysis from Message Log: completed 2026-04-28 04:16 UTC+3, "Message Log received". Diagnosis: client-side debugging exhausted. Live depth feed works (NQM26-CME.2026-04-28.depth file is being written normally). Historical backfill service rejects all HD Requests for this symbol with generic "Type unspecified" error. This pattern matches ThreadID=59249 (2020), where SC Engineering identified that a required Symbol Settings record on the server side was mistakenly cleared. Update From Server resolved that case. In my case Update From Server did NOT resolve the issue, suggesting a different server-side condition (possibly missing data on server for specific dates, or a different field type cleared). Request: please verify server-side state of NQM26-CME for historical Market Depth data. Specifically: - Is full-session historical Market Depth data for 2026-04-23 and 2026-04-24 (RTH+ETH) present on your servers? - Are there any Symbol Settings records on the server side for NQM26-CME that may need manual restoration (similar to ThreadID=59249)? Message Log was already sent via Send For Analysis on 2026-04-28 at 04:16:36 UTC+3 ("Message Log received" confirmation). Please cross- reference that log with this thread. Account: rmn_shkrv |
