+# 실전 전환 체크리스트
+
+모의 거래(paper)에서 실전(live)으로 전환하기 전에 아래 항목을 **순서대로** 모두 확인하세요.
+
+---
+
+## 1. 사전 조건
+
+### 1-1. KIS OpenAPI 실전 계좌 준비
+- [ ] 한국투자증권 계좌 개설 완료 (일반 위탁 계좌)
+- [ ] OpenAPI 실전 사용 신청 (KIS 홈페이지 → Open API → 서비스 신청)
+- [ ] 실전용 APP_KEY / APP_SECRET 발급 완료
+- [ ] KIS_ACCOUNT_NO 형식 확인: `XXXXXXXX-XX` (8자리-2자리)
+
+### 1-2. 리스크 파라미터 검토
+- [ ] `CIRCUIT_BREAKER_PCT` 확인: 기본값 -3.0% (더 엄격하게 조정 권장)
+- [ ] `FAT_FINGER_PCT` 확인: 기본값 30.0% (1회 주문 최대 잔고 대비 %)
+- [ ] `CONFIDENCE_THRESHOLD` 확인: BEARISH ≥ 90, NEUTRAL ≥ 80, BULLISH ≥ 75
+- [ ] 초기 투자금 결정 및 해외 주식 운용 한도 설정
+
+### 1-3. 시스템 요건
+- [ ] 커버리지 80% 이상 유지 확인: `pytest --cov=src`
+- [ ] 타입 체크 통과: `mypy src/ --strict`
+- [ ] Lint 통과: `ruff check src/ tests/`
+
+---
+
+## 2. 환경 설정
+
+### 2-1. `.env` 파일 수정
+
+```bash
+# 1. KIS 실전 URL로 변경 (모의: openapivts 포트 29443)
+KIS_BASE_URL=https://openapi.koreainvestment.com:9443
+
+# 2. 실전 APP_KEY / APP_SECRET으로 교체
+KIS_APP_KEY=<실전_APP_KEY>
+KIS_APP_SECRET=<실전_APP_SECRET>
+KIS_ACCOUNT_NO=<실전_계좌번호>
+
+# 3. 모드를 live로 변경
+MODE=live
+
+# 4. PAPER_OVERSEAS_CASH 비활성화 (live 모드에선 무시되지만 명시적으로 0 설정)
+PAPER_OVERSEAS_CASH=0
+```
+
+> ⚠️ `KIS_BASE_URL` 포트 주의:
+> - **모의(VTS)**: `https://openapivts.koreainvestment.com:29443`
+> - **실전**: `https://openapi.koreainvestment.com:9443`
+
+### 2-2. TR_ID 자동 분기 확인
+
+아래 TR_ID는 `MODE` 값에 따라 코드에서 **자동으로 선택**됩니다.
+별도 설정 불필요하나, 문제 발생 시 아래 표를 참조하세요.
+
+| 구분 | 모의 TR_ID | 실전 TR_ID |
+|------|-----------|-----------|
+| 국내 잔고 조회 | `VTTC8434R` | `TTTC8434R` |
+| 국내 현금 매수 | `VTTC0012U` | `TTTC0012U` |
+| 국내 현금 매도 | `VTTC0011U` | `TTTC0011U` |
+| 해외 잔고 조회 | `VTTS3012R` | `TTTS3012R` |
+| 해외 매수 | `VTTT1002U` | `TTTT1002U` |
+| 해외 매도 | `VTTT1001U` | `TTTT1006U` |
+
+> **출처**: `docs/한국투자증권_오픈API_전체문서_20260221_030000.xlsx` (공식 문서 기준)
+
+---
+
+## 3. 최종 확인
+
+### 3-1. 실전 시작 전 점검
+- [ ] DB 백업 완료: `data/trade_logs.db` → `data/backups/`
+- [ ] Telegram 알림 설정 확인 (실전에서는 알림이 더욱 중요)
+- [ ] 소액으로 첫 거래 진행 후 TR_ID/계좌 정상 동작 확인
+
+### 3-2. 실행 명령
+
+```bash
+# 실전 모드로 실행
+python -m src.main --mode=live
+
+# 대시보드 함께 실행 (별도 터미널에서 모니터링)
+python -m src.main --mode=live --dashboard
+```
+
+### 3-3. 실전 시작 직후 확인 사항
+- [ ] 로그에 `MODE=live` 출력 확인
+- [ ] 첫 잔고 조회 성공 (ConnectionError 없음)
+- [ ] Telegram 알림 수신 확인 ("System started")
+- [ ] 첫 주문 후 KIS 앱에서 체결 내역 확인
+
+---
+
+## 4. 비상 정지 방법
+
+### 즉각 정지
+```bash
+# 터미널에서 Ctrl+C (정상 종료 트리거)
+# 또는 Telegram 봇 명령:
+/stop
+```
+
+### Circuit Breaker 발동 시
+- CB가 발동되면 자동으로 거래 중단 및 Telegram 알림 전송
+- CB 임계값: `CIRCUIT_BREAKER_PCT` (기본 -3.0%)
+- **임계값은 엄격하게만 조정 가능** (더 낮은 음수 값으로만 변경)
+
+---
+
+## 5. 롤백 절차
+
+실전 전환 후 문제 발생 시:
+
+```bash
+# 1. 즉시 .env에서 MODE=paper로 복원
+# 2. 재시작
+python -m src.main --mode=paper
+
+# 3. DB에서 최근 거래 확인
+sqlite3 data/trade_logs.db "SELECT * FROM trades ORDER BY id DESC LIMIT 20;"
+```

+
+2. `src/main.py`

+   - `trading_cycle`, `run_daily_session` 국내 주문 `price=0` → 지정가:
+     BUY +0.2% / SELL -0.2%, `kr_round_down` KRX 틱 반올림 적용
+   - `handle_domestic_pending_orders` 함수: BUY→취소+쿨다운, SELL→취소+재주문(-0.4%, 최대1회)
+   - daily/realtime 두 모드에서 domestic pending 체크 호출 추가

+### 해외잔고 ghost position 수정 — '모의투자 잔고내역이 없습니다' 반복 방지 (#235)
+
+**배경:**
+- 모의투자 실행 시 MLECW, KNRX, NBY, SNSE 등 만료/정지된 종목에 대해
+  `모의투자 잔고내역이 없습니다` 오류가 매 사이클 반복됨
+
+**근본 원인:**
+1. `ovrs_cblc_qty` (해외잔고수량, 총 보유) vs `ord_psbl_qty` (주문가능수량, 실제 매도 가능)
+   - 기존 코드: `ovrs_cblc_qty` 우선 사용 → 만료 Warrant가 `ovrs_cblc_qty=289456`이지만 실제 `ord_psbl_qty=0`
+   - startup sync / build_overseas_symbol_universe가 이 종목들을 포지션으로 기록
+2. SELL 실패 시 DB 포지션이 닫히지 않아 다음 사이클에서도 재시도 (무한 반복)
+
+**구현 내용:**
+
+1. `src/main.py` — `_extract_held_codes_from_balance`, `_extract_held_qty_from_balance`
+   - 해외 잔고 필드 우선순위 변경: `ord_psbl_qty` → `ovrs_cblc_qty` → `hldg_qty` (fallback 유지)
+   - KIS 공식 문서(VTTS3012R) 기준: `ord_psbl_qty`가 실제 매도 가능 수량
+
+2. `src/main.py` — `trading_cycle` ghost-close 처리
+   - 해외 SELL이 `잔고내역이 없습니다`로 실패 시 DB 포지션을 `[ghost-close]` SELL로 종료
+   - exchange code 불일치 등 예외 상황에서 무한 반복 방지
+
+3. 테스트 7개 추가:
+   - `TestExtractHeldQtyFromBalance` 3개: ord_psbl_qty 우선, 0이면 0 반환, fallback
+   - `TestExtractHeldCodesFromBalance` 2개: ord_psbl_qty=0인 종목 제외, fallback
+   - `TestOverseasGhostPositionClose` 2개: ghost-close 로그 확인, 일반 오류 무시
