Improvements from a live-verified audit of the news/calendar pipeline:
- Currency tagging: keyword matching now uses letter-boundary regexes
and drops ambiguous "us "/"eu "/"uk " tokens — "versus" no longer
tags headlines as USD (confirmed live false positive polluting the
XAU/USD sentiment average).
- Fetch caching: calendar events and headlines are cached class-level
(10 min TTL, 60s retry after empty/failed fetch, lock-guarded for
concurrent scans). Stops per-scan refetching that was tripping the
Forex Factory rate limit; TTL stays under the 30-min pre-event
buffer so the danger window can't go stale.
- Surprise detection: EconomicEvent.surprise is computed from parsed
actual vs forecast (handles %, K/M/B/T suffixes, negatives). A
surprise print widens the post-release caution window to 45 min;
inline releases keep the original 15 min.
- Gold-aware sentiment: headlines are scored per currency, with
monetary-policy keywords (hawkish/rate hike/tightening vs dovish/
rate cut/easing/stimulus) inverted for XAU — "hawkish Fed" headlines
scored +1.0 for gold before, -1.0 now (verified on live feed).
- New sentiment sources: Google News gold-focused query and CNBC
Economy RSS (verified live; 40 → 74 unique headlines). Added
cross-feed title dedup so syndicated stories count once.
- events_today now buckets by UTC date (feed timestamps carry US-
Eastern offsets); --json output includes news_description.
- Removed dead NewsConfig.min_impact and unused HIGH_IMPACT_EVENTS.
Tests: 142 passed (7 new covering boundary matching, surprise
classification, post-event windows, cache reuse, gold inversion).
News engine: expand sentiment keywords (18%→60% headline coverage), add
MyFXBook RSS as fallback calendar source when Forex Factory returns 429,
add retry/backoff on calendar API rate limits, update stale ForexLive URL
to investinglive.com, add date formats without seconds for MyFXBook RSS.
