This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

Signal-intelligence platform for XAU/USD (gold — the only supported pair). It fetches OHLCV from the active data provider (Oanda v20 since 2026-07-28; Twelve Data and Tiingo remain registered fallbacks), scores 9 technical indicators per timeframe with regime-adaptive weights, checks multi-timeframe agreement and news risk, grades the signal (A+…F), and generates a full trade setup (entry, SL, TP1/TP2, trailing plan). Delivery: Telegram bot, CLI, and an Oanda practice-account auto-execution daemon. A realism-focused backtester replays history through the exact same signal code.

Every numeric threshold in config.py and pair_signals/xauusd.py was backtested or is load-bearing for a backtested result. Validation evidence lives in the factory/module docstrings and in ~/.claude/projects/.../memory/.

test_all.py is NOT pytest — it uses a custom @test("name") decorator that runs each test immediately at import; don't grep for def test_ or try pytest test_all.py. Run the whole file; it prints per-module results and exits non-zero on failure. There is no way to run a single test short of commenting modules out. Tests must stay green; every new gate/knob needs tests. When patching weekend logic in tests, patch providers.base._is_forex_weekend — but know there are THREE independent weekend implementations (providers/base.py, signal_aggregator.py, and an inline copy in backtest/gpu_backtest.py:_is_xau_blocked_by_calendar); patching the provider one does not reach the other two.

Python 3.12; a venv/ exists in-repo. Dependencies in requirements.txt (numpy, pandas, requests, twelvedata, python-telegram-bot ≥20, websockets).

Configuration & credentials

Precedence for every credential/deployment setting: env var → config.json → refuse to run (no hardcoded fallbacks). A gitignored repo-root .env is loaded at app_config import via os.environ.setdefault. config.json (gitignored; schema in config.json.example) holds secrets plus deployment settings: data_providers.active (the live-feed switch), data_providers.streaming (optional tick-stream provider for the level-breach monitor), scanning.pairs/timeframes, per-pair blocked_hours_utc, log_level. Key env vars: TELEGRAM_TOKEN, TELEGRAM_CHAT_ID, TELEGRAM_CHANNEL_ID, TWELVE_DATA_API_KEY, TIINGO_API_KEY, OANDA_ACCOUNT_ID/OANDA_API_TOKEN/OANDA_BASE_URL, DEEPSEEK_API_KEY (news LLM; the deepseek config.json block holds model/enabled/timeout/daily cap).

Architecture

End-to-end pipeline (every scan)

providers/<active>.fetch_ohlcv()       per TF: single-flight fetch, drop forming candle, validate/clean, cache
                                       (only Twelve Data rate-throttles; Oanda has no client throttle)
  → engine.TechnicalEngine.analyze()   per TF: 9 scored indicators + ATR context → regime → composite score
  → signal_aggregator.analyze_pair()   live entry point (weekend/day filters, fetch, staleness)
      └─ analyze_from_dataframes()     replayable core: MTF agreement → news → bonuses/penalties →
                                       final signal + quality grade → gates → trade setup → reasons
  → SignalReport                       consumed by telegram_bot.py, main.py, oanda_daemon.py, backtester

Signal currency everywhere is SignalStrength (−2..+2). DataFrames are UTC tz-aware, oldest-first, capitalized OHLCV columns. Everything runs on closed bars only — the forming candle is dropped, and session/hour filters evaluate bar-CLOSE time (bar label + candle duration) identically in live and backtest.

Layers

• providers/ — one class per provider subclassing BaseDataProvider (providers/base.py), which owns everything the pipeline depends on: TTL+boundary cache, forming-candle drop, freshness check, validate/clean, paginated fetch_range (feeds the backtester from any provider), optional tick streaming. Subclasses implement only _fetch_raw + symbol/interval maps. Registry + make_data_provider(config, name=None) in providers/__init__.py; config.json data_providers.active selects the live candle feed and the optional data_providers.streaming scalar selects a different provider for the tick stream. A test enforces that subclasses don't override shared base methods (supports_streaming/iter_ticks are the sanctioned streaming override points). Tiingo streams mid-price ticks (wss://api.tiingo.com/fx) — do not re-add spread display from its free FX feed (two-tier indicative quotes, removed 2026-07-23); the no-spread rule extends to the WS stream.
• engine.py — TechnicalEngine: 9 scored indicators (ema_trend, rsi, macd, bollinger, adx, roc, keltner, divergence, candlestick) + ATR as context. Regime classification (trending_up/down, trending = mixed/direction-UNKNOWN, transitioning, ranging) drives per-indicator weight multipliers and regime-aware RSI reinterpretation. Compute order matters (ATR first; MACD always computed even when not a pillar — divergence needs the histogram). Private series ride on the result as _underscore attrs; scorers/formatters skip anything _-prefixed or weight-0.
• signal_aggregator.py — MTF agreement, diminishing-decay penalty system, exhaustion hard block, quality grading, then an ordered chain of post-grade gates (session, XAU SELL quality/vol/hour, regime blocks, M5 noise gates), then three setup generators: XAU ATR (A+/A), generic swing-based, plus the M5 pullback (XAU_PB) and chart-pattern (XAU_CP, chart_patterns.py) entry paths. The PB/CP generators run AFTER the gate chain and force quality to "B"; the CP path deliberately accepts grade-F composites and re-checks only session/day/big-candle (via warning prefixes) plus its own SELL/vol/RSI gates — it does NOT re-check exhaustion or the M5 min-score/MTF gates. This is validated behavior, not a bug (2026-08-04 audit: 226/586 trades in the shipped M5 12mo book are XAU_CP, +38.9R, 104 of them exhaustion-flagged and net-positive) — changing it is a rule-1 revalidation event. TradeSetup.strategy selects trailing params; trail params are stamped on the setup from the producing config so per-TF overrides reach formatters.
• pair_signals/ — per-pair config factories. Always use the factory (produce_signal / make_config), never bare PlatformConfig() — the factory applies the config.json overlay first, then the validated per-TF deltas (M5 hour-9 block, M15 trail arm 0.70, M15 SELL-hour block, etc.; evidence in the docstring). A test enforces factory ≡ inline-config equivalence. Confirmation map: M5→[M15,H1], M15→[M5,H1], H1→[M15,H4], H4→[H1,D1].
• news_engine.py — Forex Factory calendar (MyFXBook RSS fallback) + RSS keyword sentiment with gold-inverse keywords. Class-level caches (fresh engine per scan). Optional DeepSeek enrichment via llm_client.py (requests-only, no SDK): batched headline sentiment overriding keyword scores, gold-direction on release surprises, and a market-summary blurb (SignalReport.news_summary) — display/warning-only, keyword fallback on any failure, inert without a key; prompts are static module constants (DeepSeek prefix-cache pricing) and requests send thinking: disabled (V4-Flash reasoning otherwise blows the timeout). By XAU-tuned default, event risk and sentiment warn but do not gate signals (event_risk_caps_signals=False, sentiment_affects_signals=False) — the LLM does not change that.
• telegram_bot.py — owner-locked bot + subscriber channel; candle-boundary auto-scan loops (M5/M15/H1/H4, boundary+10 s), alert quality threshold + fingerprint dedup (committed only after a successful send), 📰 LLM market-context line on alerts when available, WebSocket level-breach monitor fed by the streaming provider (data_providers.streaming, falling back to the active provider; auto-disabled when the resolved provider can't stream or has no API key — Oanda does not stream, Tiingo does). Rotating log: logs/telegram.log, 3-h rotation × 240 backups.
• oanda_daemon.py / oanda_executor.py — practice-account auto-execution. Book-parity rules (see daemon docstring): no broker-side TP (trailing model — TP1/TP2 advisory), 5-bar per-TF cooldown (wall-clock approximation, so it expires over weekends where the backtester would still count bars), trail ratchets at bar close once per observed bar (a missed/failed cycle skips those bars entirely — the intra-gap high/low never enters the peak). Accepted divergence: one position total; orders send positionFill=OPEN_ONLY so a state/broker divergence cancels the order instead of silently netting. State/broker re-sync runs at boot and after any suspicious fill (_reconcile_positions).
• dashboard_publisher.py / static/dashboard.html — web dashboard as a static publisher (live LAMP server): standalone daemon scans at candle closes via produce_signal and atomically writes snapshot.json/news.json/dashboard.html to $DASHBOARD_OUT_DIR (Apache serves them; page is public by owner decision). Hard independence rule: never imports, and is never imported by, telegram_bot/oanda_daemon — confirmation map and boundary math are deliberate local copies, so a web-side failure can only mean a stale page. Due-TF classification uses the RAW wake time (flooring wake−buffer skips every H1/H4 scan — 2026-08-02 bug). News panel reads NewsEngine.get_fundamental_context() plus the additive get_week_events() accessor (display-only; no signal path calls it); as a separate process it has its own news caches and DeepSeek daily cap. News/calendar rows are clickable (detail dialog); headlines carry id = sha1(headline) in news.json, and exactly one on-demand endpoint exists: static/news_summary.php (installed by install_static), which serves a DeepSeek gold-impact summary per headline — whitelist-gated against news.json ids, cache-forever in ai/, own fail-closed daily cap (150/day, file-based, separate from the publisher's), key at /etc/gold-dashboard/deepseek.key, never reads repo config. Deployment checklist: deploy/README-dashboard.md.
• backtest/gpu_backtest.py — bar-by-bar replay through the real analyze_from_dataframes (news off). Realism model (do not regress): next-bar-open entries re-anchored to the raw price path, round-trip --spread charged per trade, trade resolution on RAW bars (cleaning applies only to signal-side data), same-bar SL+TP tie → SL first, gap fills at bar open, trail ratchet at bar close only. Indicators are precomputed once per TF (CuPy GPU or NumPy fallback — check the Backend: log line); replay fans out over worker processes and the 5-bar cooldown is applied in an ordered pass afterwards, so parallel and sequential books are identical. Parquet cache in backtest/cache/ keyed by provider/symbol/TF/window. backtest/*.csv are gitignored pinned trade books from past campaigns — used for manual before/after comparison. backtest/instructions_for_backtest.txt lists what every backtest report must record.

Rules for making changes (read before editing signal logic)

1. Never change a tuned value without re-validation. Acceptance rule: positive total R in BOTH train and validation halves of a ≥12-month window, PF ≥ 1.3, at realistic cost (XAU $0.30 round trip), trailing exits, next-open fills. Marginal edges must additionally pass the 2024-06→2025-03 out-of-sample window — within-year splits alone have approved configs that later failed OOS.
2. Per-timeframe overrides live in the pair factory, never in global defaults — the same knob has opposite effects on different TFs (proven repeatedly: tp_floor_rr, hour-9 block, trail params). Document validation evidence in the factory docstring.
3. Pair isolation is a hard invariant. XAU gates in the aggregator are display-name-gated so a future pair port cannot inherit gold-calibrated logic by accident.
4. Live == backtest parity. If you add a live gate, add it to the replay path in the same commit; all time filters evaluate bar-close time in both paths.
5. ROC stays weighted even though it's correlated with MACD/Keltner/EMA — zeroing it backtested 13R worse; composite thresholds are calibrated with it.
6. Backtester realism knobs are results-critical (raw-path resolution, spread charging, next-open entry, SL-first ties, close-only trail). Touching them invalidates comparability with all pinned books.
7. The forming candle must stay dropped — live signals repaint otherwise.
8. Don't add config fields nothing reads; don't disable indicators in production paths (disabled_indicators is for experiments only).
9. EUR/USD was removed 2026-07-16 after a no-edge verdict (cost-to-volatility; last commit with EUR support: 7d3fd95). Do not re-add without new data. BTC/ETH work lives on unmerged branches only.

2026-08-04 QA audit — owner decisions ledger

• Weekend calendar: FIXED (owner-approved 2026-08-04). All three _is_forex_weekend copies are NY-anchored (Fri 17:00 → Sun 18:00 ET; during US DST that is Fri 21:00 UTC — measured on 5yr of Oanda bars). Kills the weekly false-"STALE DATA/feed lagging" hours. Book impact, fully accounted: M15 byte-identical; M5 12mo dropped exactly ONE trade — a phantom whose signal fired on the final summer-Friday bar (close 21:00 UTC) and "filled" at Sunday's reopen 49 h later (−1.08R, live-impossible). M5 12mo reference at HEAD: 555 trades, +98.64R PF≈1.50 @ $0.65 (was 556/+97.56/1.48). A Module 21 test sweeps all three copies hourly across both DST transitions.
• Spread in exit-trigger detection (rule 6): owner DECLINED 2026-08-04. Backtest stop triggers stay on raw mid High/Low; the measured optimism (~4–6% of total R: −3.55R @ $0.30, −4.24R @ $0.65 on the M15 12mo book) is accepted and books stay comparable. Re-open only as a conscious re-pin campaign.
• FB2_EMA_LO: HARDENED 2026-08-04 (delegated). Research override for the EMA200-proximity band, default = tuned 0.5; an unparseable value now degrades to the default with a warning instead of crashing every scan. Documented here — it is a knob that exists.
• H4 seeding divergence: parked. Live H4 fetches only 380 bars vs the backtest's unbounded history — ~2% of sampled H4 bars flip an indicator signal (composite Δ up to 12.3). M5/M15/H1 clean at their real fetch depths. Fold into any future H4 campaign; H4 remains "unproven for auto-execution".

Current state notes (2026-07-30)

• Oanda v20 is the live feed (data_providers.active: "oanda"), but the pinned backtest books are still Twelve-Data-pinned and the backtest cost assumption is $0.30 while measured real spreads are ~$0.65–0.72 — re-pin books on Oanda bars before treating feed-switch comparisons as valid (see Oanda/TD divergence study in memory).
• Human-facing docs in docs/ (user_guide.html, beginner_guide.html + PDF builds) must be kept in sync when signal behavior changes.
