📖 Introduction
QuantDinger is a Local-First quantitative trading workspace designed for traders, researchers, and geeks.
Unlike expensive SaaS platforms, QuantDinger returns data ownership to you. It features a built-in LLM-based Multi-Agent Research Team that autonomously gathers financial intelligence from the web, combines it with local market data, generates professional analysis reports, and seamlessly integrates with your strategy development, backtesting, and live trading workflows.
Core Value
- 🛡️ Privacy First: All strategies, trading logs, and API keys are stored locally in your SQLite database.
- 🧠 AI Empowered: Not just code completion, but a real AI Research Analyst (powered by OpenRouter/LLM).
- ⚡ Multi-Market: Native support for Crypto, US Stocks, CN/HK Stocks, Forex, and Futures.
- 🔌 Out-of-the-Box: One-click deployment via Docker. No complex environment setup required.

✨ Key Features
1. Universal Data Engine
Stop worrying about data APIs. QuantDinger features a powerful Data Source Factory pattern:
- Crypto: Direct API connection for trading (10+ exchanges) combined with CCXT for market data (100+ sources).
- Stocks: Integrates Yahoo Finance, Finnhub, Tiingo (US), and AkShare (CN/HK).
- Futures/Forex: Supports OANDA and major futures data sources.
- Proxy Support: Built-in proxy configuration for restricted network environments.
2. AI Multi-Agent Research
Your tireless team of analysts:
- Coordinator Agent: Decomposes tasks and manages workflows.
- Research Agent: Performs full-web searches (Google/Bing) for macro news.
- Crypto/Stock Agent: Specializes in technical and capital flow analysis for specific markets.
- Report Generation: Automatically produces structured Daily/Weekly research reports.
2.1 🧠 Memory-Augmented Agents (Local RAG + Reflection Loop)
QuantDinger’s agents don’t start from scratch every time. The backend includes a local memory store and an optional reflection/verification loop:
- What it is: RAG-style experience retrieval injected into agent prompts (NOT model fine-tuning).
- Where it lives: Local SQLite files under
backend_api_python/data/memory/(privacy-first).

Config lives in .env (see backend_api_python/env.example): ENABLE_AGENT_MEMORY, AGENT_MEMORY_TOP_K, AGENT_MEMORY_ENABLE_VECTOR, AGENT_MEMORY_HALF_LIFE_DAYS, and ENABLE_REFLECTION_WORKER.
3. Robust Strategy Runtime
- Thread-Based Executor: Independent thread pool management for strategy execution.
- Auto-Restore: Automatically resumes running strategies after system restarts.
- Pending Order Worker: Reliable background queue ensures precise signal execution and prevents slippage.
4. Modern Tech Stack

Quick Start
Option 1: Docker Deployment (Recommended)
The fastest way to get QuantDinger running.
1. Start Services
Linux / macOS
git clone https://github.com/brokermr810/QuantDinger.git && \
cd QuantDinger && \
cp backend_api_python/env.example backend_api_python/.env && \
docker-compose up -d --build
Windows (PowerShell)
git clone https://github.com/brokermr810/QuantDinger.git
cd QuantDinger
Copy-Item backend_api_python\env.example -Destination backend_api_python\.env
docker-compose up -d --build
2. Configuration & Access
- Frontend UI: http://localhost:8888
- Default Account:
quantdinger/123456
Note
: For production or AI features, edit
backend_api_python/.env(addOPENROUTER_API_KEY, change passwords) and restart withdocker-compose restart backend.
3. Access the Application
- Frontend UI: http://localhost
- Backend API: http://localhost:5000

Docker Network
- Frontend: Vue.js app served by Nginx, proxies API requests to backend
- Backend: Python Flask API service
Data Persistence
The following data is mounted to the host and persists across container restarts:
volumes:
- ./backend_api_python/quantdinger.db:/app/quantdinger.db # Database
- ./backend_api_python/logs:/app/logs # Logs
- ./backend_api_python/data:/app/data # Data directory
- ./backend_api_python/.env:/app/.env # Configuration
Customization
Change ports - Edit docker-compose.yml:
services:
frontend:
ports:
- "8080:80" # Change to port 8080
backend:
ports:
- "5001:5000" # Change to port 5001
Configure HTTPS - Use a reverse proxy (like Caddy/Nginx):
# Using Caddy (automatic HTTPS)
caddy reverse-proxy --from yourdomain.com --to localhost:80
Production Recommendations
Security:
# Generate strong SECRET_KEY
openssl rand -hex 32
# Set secure admin password
ADMIN_PASSWORD=your-very-secure-password
Resource limits - Add to docker-compose.yml:
services:
backend:
deploy:
resources:
limits:
cpus: '2'
memory: 2G
reservations:
cpus: '0.5'
memory: 512M
Log management:
services:
backend:
logging:
driver: "json-file"
options:
max-size: "100m"
max-file: "3"
Docker Troubleshooting
Frontend can't connect to backend:
docker-compose logs backend
curl http://localhost:5000/api/health
Database permission issues:
chmod 666 backend_api_python/quantdinger.db
Build failures:
# Clear Docker cache and rebuild
docker-compose build --no-cache
Out of memory:
# Check memory usage
docker stats
# Add swap space (Linux)
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Updating
# Pull latest code
git pull
# Rebuild and restart
docker-compose up -d --build
Backup
# Backup database
cp backend_api_python/quantdinger.db backup/quantdinger_$(date +%Y%m%d).db
# Backup configuration
cp backend_api_python/.env backup/.env_$(date +%Y%m%d)
Option 2: Local Development
Prerequisites
- Python 3.10+ recommended
- Node.js 16+ recommended
1. Start the backend (Flask API)
cd backend_api_python
pip install -r requirements.txt
cp env.example .env # Windows: copy env.example .env
python run.py
Backend will be available at http://localhost:5000.
2. Start the frontend (Vue UI)
cd quantdinger_vue
npm install
npm run serve
Frontend dev server runs at http://localhost:8000 and proxies /api/* to http://localhost:5000 (see quantdinger_vue/vue.config.js).
Configuration (.env)
Use backend_api_python/env.example as a template. Common settings include:
- Auth:
SECRET_KEY,ADMIN_USER,ADMIN_PASSWORD - Server:
PYTHON_API_HOST,PYTHON_API_PORT,PYTHON_API_DEBUG - Database:
SQLITE_DATABASE_FILE(optional; default isbackend_api_python/data/quantdinger.db) - AI / LLM:
OPENROUTER_API_KEY,OPENROUTER_MODEL, timeouts - Web search:
SEARCH_PROVIDER,SEARCH_GOOGLE_*,SEARCH_BING_API_KEY - Proxy (optional):
PROXY_PORTorPROXY_URL - Workers:
ENABLE_PENDING_ORDER_WORKER,DISABLE_RESTORE_RUNNING_STRATEGIES
API
The backend provides REST endpoints for login, market data, indicators, backtesting, strategies, and AI analysis.
- Health:
GET /health(also supportsGET /api/healthfor deployment probes) - Auth (frontend-compatible):
POST /api/user/login,POST /api/user/logout,GET /api/user/info
For the full route list, see backend_api_python/app/routes/.
