About this skill

FVG-Delta Forex Signal Engine v6.0

A production FastAPI service that scans the global forex market on 15-minute candles, runs a strict lock-forward Smart-Money-Concept (SMC) staged state machine, and alerts on the late stages. It is the forex evolution of the FVG-Delta crypto engine — identical strategy, refined for forex speed and mechanics.

What it scans

A curated, liquidity-screened universe (no illiquid exotics, no single stocks), defined in assets/instruments.py:

  • FX majors & minors (EUR/USD, GBP/JPY, EUR/GBP, …)
  • Metals (XAU/USD gold, XAG/USD silver)
  • Energy (WTI, Brent, NatGas)
  • Indices (NAS100, S&P500, US30, DAX, FTSE100, Nikkei225, DXY)

Data is pulled from Yahoo Finance via yfinance — real 15m OHLC, no API key.

The strategy (unchanged from crypto)

Stage 0 FVG/impulse context → Stage 1 first-liquidity lock + BoS close → Stage 2 liquidity sweep (close-through) → Stage 3 FVG interaction → Stage 4 opposite-direction confirmation = verified entry. Lock-forward: each transition is searched once and locked; stages never silently regress.

Forex refinements

  • Risk model: pips / lot (default micro 0.01) / LEVERAGE (default 500, margin only) / required margin / $ risk-reward (P/L = pips × pip-value × lots). Spread-aware. Replaces the crypto ROI/auto-leverage model.
  • Intrabar Stage 3 + exits: FVG touch registers on the forming candle; SL / TP / Break-even fire intrabar. Structural stages (1/2) stay close-based.
  • No TTL on Stage 3/4: they resolve only on real triggers (Stage 3: close through FVG; Stage 4: SL / TP / Break-even).
  • Market clock: Open/Closed badge, weekend + holidays, browser-tz countdown.
  • News radar: ForexFactory weekly feed graded Safe / Caution / No-Trade with a short label + countdown, shown on the dashboard and inside Telegram alerts.

Run it

# 1. credentials (never paste keys in chat — use the secure env flow)
cp .env.example .env   # set TELEGRAM_BOT_TOKEN + TELEGRAM_CHAT_ID; optional LEVERAGE / LOT_SIZE
# 2. local
bash assets/run_one_shot.sh
# 3. docker / Hugging Face Spaces (Docker SDK)
docker build -t fvg-forex assets/ && docker run -p 7860:7860 --env-file .env fvg-forex

Endpoints: / (dashboard), /health, /api/state, /api/market, /api/news, /api/chart.png?symbol=EUR/USD. Without Telegram creds the UI still runs; alerts are skipped and logged.

Tuning & gotchas

  • All knobs are env vars with production-safe defaults — see assets/VARIABLES_AND_SECRETS_GUIDE.txt.
  • Structural stages (1/2) decide on the last CLOSED candle (bars[-2]); Stage-3 touch and SL/TP/BE use the forming candle (bars[-1]) when INTRABAR_* is on.
  • Cron/weekly times are UTC. The dashboard renders all times + countdowns in the viewer's browser timezone.
  • yfinance needs outbound access to Yahoo; the news radar needs ForexFactory. Both are keyless. If a feed is unreachable the engine degrades gracefully.
  • Pip values are broker-approximate defaults (override via FVG_PIPVAL_<PAIR>).
