Records direction, size, entry price, + bars held, MFE, and entry ATR. + +2. **Reconciliation manager** — on startup, loads the journal and compares it + against live broker positions via `GET /positions`. The broker is the + **source of truth**; the journal is a crash-recovery hint. + +--- + +## Recovery Scenarios + +### 1. Normal restart (broker and journal agree) + +Outcome: positions are fully restored with all metadata intact. + +``` +Journal: EURUSD LONG size=1.0 bars_held=5 mfe=2.5 +Broker: EURUSD BUY size=1.0 +→ MATCHED — position restored from journal (preserves bars_held, mfe, entry_atr) +``` + +No manual action required. + +--- + +### 2. Phantom local position (journal says open, broker says flat) + +The position was closed at the broker (manually, or a fill arrived after the +crash) but the journal still shows it as open. + +``` +Journal: EURUSD LONG size=1.0 +Broker: (no position) +→ PHANTOM_LOCAL — local state reset to flat, journal updated +``` + +Outcome: strategy resets to flat. No manual action required. + +--- + +### 3. Orphan broker position (journal empty, broker has a position) + +The journal was not written before the crash (e.g. crash on entry), but the +order was accepted by the broker. + +``` +Journal: (no entry for EURUSD) +Broker: EURUSD BUY size=1.0 +→ ORPHAN_BROKER — position adopted into local state, post-warmup exit check runs +``` + +After adoption the strategy runs `check_restored_position` against the latest +candle. If an exit condition is met the position is closed immediately. + +No manual action required, but review the logs for adopted positions and verify +the exit evaluation result. + +--- + +### 4. Failed exit (EMERGENCY) + +The strategy attempted to close a position (journal direction=None) but the +broker still has it open. This is the most critical scenario. + +``` +Journal: EURUSD direction=None (flat) +Broker: EURUSD BUY size=1.0 +→ FAILED_EXIT — CRITICAL log emitted, broker position adopted +``` + +**Action required:** + +1. Check the log for `FAILED EXIT DETECTED` to identify the instrument. +2. Log into the IG web platform and verify the position manually. +3. If the position should be closed: close it manually via the IG platform. +4. Once flat, restart the portfolio process. The journal will reconcile to flat. + +--- + +### 5. Size mismatch (partial fill) + +The journal records the requested size but the broker filled a smaller amount. + +``` +Journal: EURUSD LONG size=2.0 +Broker: EURUSD BUY size=1.5 +→ SIZE_MISMATCH — local size corrected to broker size (1.5) +``` + +No manual action required. Exit logic re-evaluated with broker size. + +--- + +### 6. Direction mismatch + +The journal records one direction but the broker has the opposite. + +``` +Journal: EURUSD LONG size=1.0 +Broker: EURUSD SELL size=1.0 +→ DIRECTION_MISMATCH — broker direction adopted, exit check runs +``` + +This is unusual and may indicate a separate manual trade on the same epic. +Review the IG platform to verify the direction before restarting. + +--- + +### 7. Broker unreachable on startup + +If the broker API is unavailable, the manager falls back to the journal alone +and restores positions without verification. + +``` +Broker: HTTP 500 / timeout +→ Positions restored from journal (unverified) +``` + +**Action required:** + +1. Monitor logs for `restoring from journal only`. +2. Once the broker is reachable, the next **periodic reconciliation** will + verify and correct state automatically (default: every 4 candles). +3. Until then, treat restored positions as tentative — do not add to them. + +--- + +### 8. Corrupt journal + +If `positions.json` is corrupt (disk error, interrupted write), the manager +logs the error, discards the journal, and falls back to broker positions. + +``` +Journal: unreadable (corrupt JSON) +→ load() returns None → broker positions adopted as orphans +``` + +No manual action required. If the broker shows no open positions, the process +starts fresh. + +--- + +## Manual Intervention Steps + +When a `FAILED_EXIT` is detected or you need to manually force a clean state: + +```bash +# 1. Stop the portfolio process +pkill -f ig_trader # or stop the container / systemd unit + +# 2. Inspect the journal +cat /path/to/journal/positions.json | python3 -m json.tool + +# 3. If you want to clear the journal entirely (e.g. all positions confirmed flat) +rm /path/to/journal/positions.json + +# 4. Restart the process — it will reconcile against the broker +python -m ig_trader # or start container +``` + +> **Warning:** Only delete the journal after confirming all positions are +> flat at the broker. Deleting while positions are open will force orphan +> adoption on restart, which triggers exit checks but may have slippage +> implications. + +--- + +## Log Messages Reference + +| Level | Message fragment | Meaning | +|----------|-----------------------------------------------|--------------------------------------------| +| INFO | `Journal loaded: N entries (M open, K flat)` | Normal startup with journal | +| INFO | `No journal found; starting fresh` | First run or clean shutdown | +| INFO | `Startup reconciliation: all N positions match` | Clean reconciliation | +| WARNING | `Phantom position cleared: INSTRUMENT` | Closed externally; local reset to flat | +| WARNING | `Adopting orphan broker position: INSTRUMENT` | No journal entry; broker state adopted | +| WARNING | `Size corrected: INSTRUMENT` | Partial fill reconciled | +| WARNING | `Direction corrected: INSTRUMENT` | Direction mismatch; broker wins | +| CRITICAL | `FAILED EXIT DETECTED: INSTRUMENT` | **Manual intervention required** | +| WARNING | `restoring from journal only` | Broker unavailable at startup | +| WARNING | `Heartbeat Alert: no updates for N in Xs` | Lightstreamer connection may be stale | + +--- + +## Periodic Reconciliation + +Even during normal operation, the manager reconciles every `reconcile_interval` +target-period candles (default: 4). This catches any drift that occurs during +live trading without requiring a restart. + +Instruments with **recent position changes** are excluded from a single +periodic check to avoid false positives
