From 7e27b8d19b3b9b3b3cd88a9304f04e10bf09e94a Mon Sep 17 00:00:00 2001 From: Matt Spinola Date: Sun, 26 Jul 2026 18:10:04 -0400 Subject: [PATCH] Mark DX as not-on-databento (ICE product), add Yahoo fallback DX (US Dollar Index) trades on ICE, not CME Globex, so databento's GLBX.MDP3 carries no series for it. But `databento` defaults to the internal symbol, so the producer queried `DX.n.0` on GLBX and got empty results across every paged window, leaving no ohlcv file and a hollow statistics manifest marker, and it would re-scan DX empty on every future run. Set `databento: null` so the databento producer skips DX (mirrors the ICE softs), and add `yahoo: DX-Y.NYB` (cash DXY) as the cross-platform fallback, since Yahoo has no working DX futures ticker (DX=F returns empty; DX-Y.NYB verified live). Norgate still serves DX for local research.
