When Trump posts an actionable buy/short signal, instantly tweet the call
(entry/direction, hard time window, "ratio me" hook), then post a result
follow-up X_FOLLOWUP_MINUTES later reporting the realised 15-min move plus
a recent hit-rate brag with the site link.
- New app/services/x_poster.py: OAuth 1.0a signed (stdlib hmac, no new dep,
httpx reused). Fire-and-forget, fully degradable — no-op unless X creds +
x_enabled. Dry-run logs tweet text. In-memory UTC-daily cap. 280-char hard
cap on all templates (no Premium).
- Gated to source=truth buy/short above x_min_confidence; scanner signals
excluded (don't fit the "Trump just posted" format).
- Hooked next to notify_signal in /signals/ingest + both Trump pollers
(dedup via unique external_id → single tweet per post).
- config.py + .env.example: X_API_KEY/SECRET, X_ACCESS_TOKEN/SECRET,
X_ENABLED, X_MIN_CONFIDENCE, X_DAILY_CAP, X_FOLLOWUP_MINUTES, X_LINK_URL.
72 tests pass.
