 ## 주의사항
 
 1. **JPA FK vs 논리 참조**: `users`, `strategy_rule` 등을 참조하는 컬럼 다수가 JPA `@ManyToOne` 없이 Long ID만 보관하므로 DB 레벨 FK 제약이 없습니다. 참조 무결성은 애플리케이션 로직에 의존합니다.

+# 모의투자 투자금·종목별 관리 설계
+
+상용 주식/HTS 프로그램(키움 영웅문 모의, NH/미래 HTS 모의, TradingView Paper 등)에서 통상 제공하는 **계좌·투자금·종목별 배분·수익률·거래내역** 구조를 기준으로, goldenChart **현재 구현(as-is)** 과 **목표(to-be)** 를 정리한 설계서입니다.
+
+---
+
+## 1. 목표
+
+| 목표 | 설명 |
+|------|------|
+| **투자금 단일 원천** | 모의 계좌의 현금·총자산·초기자본·실현/평가 손익을 DB에서 일관되게 관리 |
+| **종목별 투자 한도** | 종목마다 최대 투자금(또는 비율)을 두고 매수 시 한도 초과 방지 |
+| **투자금 설정 vs 관리 분리** | 설정(규칙·초기화) 화면과 운영(잔고·보유·체결) 화면 역할 분리 |
+| **종목별 매수/매도** | 수동 주문·전략 자동매매가 동일 계좌·동일 한도 규칙을 따름 |
+| **가상매매 연동** | 가상투자 대시보드·모의투자 메뉴가 **동일 `gc_paper_*` 계좌** 를 참조 |
+
+---
+
+## 2. 현재 구현 (As-Is)
+
+### 2.1 DB (V18)
+
+```
+gc_app_settings          ← 전역: 초기자본, 수수료, 슬리피지, 자동매매 ON/OFF, 매수 예산 %
+        │
+        ▼
+gc_paper_account         ← device_id당 1계좌: cash_balance, realized_pnl
+        │
+        ├── gc_paper_position   ← 종목별: quantity, avg_price (한도·배분 없음)
+        └── gc_paper_trade      ← 체결 이력: BUY/SELL, fee, cash_after
+```
+
+### 2.2 API
+
+| 메서드 | 경로 | 용도 |
+|--------|------|------|
+| GET/POST | `/api/paper/summary` | 계좌 요약·보유·평가손익(markPrices 선택) |
+| GET | `/api/paper/trades` | 체결 목록 |
+| POST | `/api/paper/orders` | 즉시 체결 주문 |
+| POST | `/api/paper/reset` | 계좌 초기화 |
+
+### 2.3 화면
+
+| 화면 | 위치 | 역할 |
+|------|------|------|
+| **가상매매 설정** | 설정 → 가상매매 | 초기자본·수수료·자동매매 (전역) |
+| **모의투자 설정 탭** | 모의투자 좌측 | 위와 동일 항목 + 계좌 초기화 |
+| **모의투자 대시보드** | 메뉴 모의투자 | KPI·보유·체결·차트·수동 매수/매도 |
+| **가상투자** | 메뉴 가상투자 | 전략 모니터링 + `placePaperOrder` 자동/수동 |
+
+### 2.4 부족한 점 (Gap)
+
+- **종목별 투자금 한도** 없음 → 전역 `paper_auto_trade_budget_pct` 만 존재
+- **현금 변동 원장**(입금/출금/수수료/초기화) 미분리 → `cash_after` 만 체결에 기록
+- **일별 자산 스냅샷** 없음 → 수익률 차트는 프론트가 체결만 재구성
+- **미체결 주문** 없음 → 모두 즉시 체결
+- **종목별 실현손익·회전율** 집계 테이블 없음
+- **투자금 설정** 이 설정 앱 + 모의투자에 이중 노출
+

+
+| 영역 | 통상 기능 | goldenChart 매핑 |
+|------|-----------|------------------|
+| 계좌 개설 | 초기 예탁금 설정 | `paper_initial_capital` + `gc_paper_account` |
+| 계좌 초기화 | 잔고·보유·내역 리셋 | `POST /paper/reset` (유지·이력 테이블 추가 권장) |
+| 예수금/주문가능 | 현금, D+0 가용 | `cash_balance` − `reserved_cash` |
+| 종목별 매수한도 | 종목당 상한 또는 비중 상한 | **신규** `gc_paper_symbol_allocation` |
+| 보유종목 | 수량·평단·평가·손익률·비중 | `gc_paper_position` + summary API 확장 |
+| 체결내역 | 일자·종목·매수/매도·가격·수량·수수료 | `gc_paper_trade` (필터·페이징 추가) |
+| 자산추이 | 일별 총자산 그래프 | **신규** `gc_paper_daily_snapshot` |
+| 원장/자금변동 | 입출금·수수료·배당·이자 | **신규** `gc_paper_cash_ledger` |
+| 수동 주문 | 지정가/시장가·수량·금액 | `TradeOrderPanel` + `/paper/orders` |
+| 자동매매 | 전략 시그널 연동 | STOMP 시그널 → `placePaperOrder` |

+
+| 단계 | 범위 | 산출물 |
+|------|------|--------|
+| **P0** | DB V51 + allocation CRUD + 매수 한도 검증 | 마이그레이션, API, 단위 테스트 |

+| **P4** | (선택) 미체결 주문 | gc_paper_order |
+
+---
+
+## 9. goldenChart 적용 시 유의사항
+
+1. **단일 계좌**: `device_id` 기준 1계좌 유지 (상용 모의도 대부분 1:1).
+2. **평가 시세**: summary는 `POST /paper/summary` + markPrices 패턴 유지.
+3. **색상**: 매수 `#ef5350`, 매도 `#4dabf7` (`--gc-trade-buy/sell`).
+4. **전략 평가와 분리**: Ta4j 시그널은 `gc_paper_*` 체결만 변경; 전략 DSL 평가는 기존 백엔드 단일 경로 유지.
+5. **설정 이중화 해소**: `SettingsPage` 가상매매 = 전역 기본값, 모의투자 좌측 설정 = 동일 API 바인딩 또는 “설정으로 이동” 링크만.
+

+
