# myFidelityTracker - Project Summary

## Overview
Complete MVP for tracking Fidelity brokerage account performance with transaction import, position tracking, and real-time P&L calculations.

## What's Been Built

### ✅ Backend (Python/FastAPI)
- **Database Models**: Account, Transaction, Position (with junction tables)
- **CSV Parser**: Fidelity-specific parser with deduplication
- **Services**:
  - Import Service (file upload + filesystem import)
  - Position Tracker (FIFO matching, options support)
  - Performance Calculator (with Yahoo Finance integration)
- **API Endpoints**:
  - Accounts (CRUD)
  - Transactions (list, filter, pagination)
  - Positions (open/closed, stats)
  - Analytics (overview, balance history, top trades)
  - Import (upload + filesystem)
- **Database**: PostgreSQL with Alembic migrations
- **Features**: Deduplication, real-time P&L, market data caching

### ✅ Frontend (React/TypeScript)
- **Components**:
  - Dashboard (metrics cards + charts)
  - Account Manager (create/list/delete accounts)
  - Import Dropzone (drag-drop + filesystem import)
  - Transaction Table (filterable, sortable)
  - Position Cards (open/closed with P&L)
  - Performance Chart (balance over time)
  - Metrics Cards (KPIs)
- **Styling**: TailwindCSS with Robinhood-inspired design
- **State Management**: React Query for data fetching
- **Routing**: Tab-based navigation

### ✅ Infrastructure
- **Docker Compose**: Multi-container setup (postgres, backend, frontend)
- **Nginx**: Reverse proxy for SPA routing + API proxying
- **Multi-arch**: Supports amd64 and arm64
- **Volumes**: Persistent database + import directory
- **Health Checks**: Service readiness monitoring

### ✅ Developer Experience
- **Documentation**:
  - README.md (comprehensive guide)
  - QUICKSTART.md (2-minute setup)
  - API docs (auto-generated at /docs)
- **Scripts**:
  - start.sh (automated startup with health checks)
  - stop.sh (graceful shutdown)
  - seed_demo_data.py (demo data loader)
- **Environment**: .env.example template
- **Git**: .gitignore configured

## Key Features

### Transaction Management
- Import via CSV upload or filesystem
- Automatic deduplication using SHA-256 hashing
- Support for stocks, calls, puts
- Handle assignments, expirations, rolls

### Position Tracking
- Automatic FIFO matching
- Multi-leg position support
- Open vs. closed positions
- Partial position closes
- Average entry/exit prices

### Performance Analytics
- Realized P&L (closed positions)
- Unrealized P&L (open positions with live prices)
- Win rate calculation
- Average win/loss metrics
- Top trades analysis
- Balance history charting

### User Experience
- Clean, modern UI (Robinhood-inspired)
- Mobile-responsive design
- Real-time data updates
- Intuitive navigation
- Error handling with user feedback

## Architecture

### Data Flow
```
CSV File → Parser → Deduplication → Database (Transactions)
                                          ↓
                                  Position Tracker (FIFO)
                                          ↓
                                     Positions DB
                                          ↓
                           Performance Calculator + Yahoo Finance
                                          ↓
                                    Analytics API
                                          ↓
                                   React Frontend
```

### Tech Stack
- **Backend**: Python 3.11, FastAPI, SQLAlchemy, PostgreSQL, Pandas, yfinance
- **Frontend**: React 18, TypeScript, Vite, TailwindCSS, React Query, Recharts
- **Infrastructure**: Docker, Docker Compose, Nginx

## Getting Started

### Quick Start
```bash
cd /Users/chris/Desktop/fidelity
./start.sh
```

### Access
- Frontend: http://localhost:3000
- Backend: http://localhost:8000
- API Docs: http://localhost:8000/docs

### Demo Data
```bash
cp History_for_Account_X38661988.csv imports/
docker-compose exec backend python seed_demo_data.py
```

## Testing Checklist

### ✅ To Test
1. Start application (`./start.sh`)
2. Create account via UI
3. Import sample CSV
4. Verify transactions imported
5. Check positions calculated
6. View dashboard metrics
7. Test filters and sorting
8. Verify P&L calculations
9. Check responsive design
10. Test re-import (deduplication)

## Future Enhancements
- [ ] Additional brokerages (Schwab, E*TRADE, Robinhood)
- [ ] Authentication/multi-user
- [ ] Tax reporting (wash sales, capital gains)
- [ ] Email notifications
- [ ] Dark mode
- [ ] PDF export
- [ ] AI trade recommendations
- [ ] Backtesting

## Notes
- Uses FIFO for position matching
- Market data cached for 60 seconds
- Options pricing uses Yahoo Finance (may not be perfect)
- Designed for personal use (single-user)
