## 📖 Introduction
### What is QuantDinger?
QuantDinger is a **local-first, privacy-first, self-hosted quantitative trading infrastructure**. It runs on your own machine/server, providing **multi-user accounts backed by PostgreSQL** while keeping full control of your strategies, trading data, and API keys.
### Why Local-First?
Unlike SaaS platforms that lock your data and strategies in the cloud, QuantDinger runs locally. Your strategies, trading logs, API keys, and analysis results stay on your machine. No vendor lock-in, no data exfiltration.
### Who is this for?
QuantDinger is built for traders, researchers, and engineers who:
- Value data sovereignty and privacy
- Want transparent, auditable trading infrastructure
- Prefer engineering over marketing
- Need a complete workflow: data, analysis, backtesting, and execution
### Core Value
- **🔓 Apache 2.0 Open Source (Code)**: Permissive and commercial-friendly
- **🐍 Python-Native & Visual**: Write indicators in Python with AI assistance, visualize on built-in K-line charts
- **🤖 AI-Loop Optimization**: AI analyzes backtest results to suggest parameter tuning, forming a closed optimization loop
- **🌍 Universal Market Access**: Crypto (Live), US Stocks (IBKR), Forex (MT5), Futures (Data/Notify)
- **💳 Built-in Monetization**: Membership subscription, credit system, USDT on-chain payment
- **⚡ Docker & Clean Arch**: 4-line command deployment with modern tech stack

## ✨ Key Features
### 1. Visual Python Strategy Workbench
*Better than PineScript, Smarter than SaaS.*
- **Python Native**: Write indicators and strategies in Python. Leverage the entire Python ecosystem (Pandas, Numpy, TA-Lib) instead of proprietary languages like PineScript.
- **"Mini-TradingView" Experience**: Run your Python indicators directly on the built-in K-line charts. Visually debug buy/sell signals on historical data.
- **AI-Assisted Coding**: Let the built-in AI write the complex logic for you. From idea to code in seconds.
### 2. Complete Trading Lifecycle
*From Indicator to Execution, Seamlessly.*
1. **Indicator**: Define your market entry/exit signals.
2. **Strategy Config**: Simplified creation with smart defaults (15min K-line, 5x leverage, market order). Advanced mode available for full customization.
3. **Backtest & AI Optimization**: Run backtests, view rich performance metrics, and **let AI analyze the result to suggest improvements**.
4. **Execution Mode**:
- **Live Trading**:
- **Cryptocurrency**: Direct API execution for 10+ exchanges (Binance, OKX, Bitget, Bybit, etc.)
- **US Stocks**: Via Interactive Brokers (IBKR)
- **Forex**: Via MetaTrader 5 (MT5)
- **Signal Notification**: Send signals via Telegram, Discord, Email, SMS, or Webhook.
5. **Risk Control**: Mandatory disclaimer acknowledgment before live trading. Market order mode by default for reliable execution.
### 3. AI-Powered Analysis & Trading Radar
*Fast, Accurate, Multi-Market Intelligence.*
- **Fast Analysis Mode**: Single LLM call architecture for quick, accurate analysis
- **AI Trading Opportunities Radar** 🆕: Auto-scans Crypto, US Stocks, and Forex markets every hour, displaying opportunities in a rolling carousel
- **ATR-Based Trading Levels**: Stop-loss and take-profit recommendations based on technical analysis
- **Analysis Memory**: Store analysis results for history review and continuous learning
- **Strategic Integration**: AI analysis can serve as a "Market Filter" for your strategies
### 4. Membership & Billing System 🆕
*Built-in Monetization for SaaS Deployment.*
- **Subscription Plans**: Monthly / Yearly / Lifetime tiers with configurable pricing
- **Credit System**: Each plan includes credits; lifetime members receive monthly credit bonuses
- **USDT On-Chain Payment** 💰: TRC20 scan-to-pay with HD Wallet (xpub) address derivation per order, automatic on-chain reconciliation via TronGrid API
- **Admin Configuration**: All plan prices, credits, and payment settings configurable via System Settings
### 5. Indicator Community & VIP System
*Share, Discover, and Trade Indicators.*
- **Publish & Share**: Share your Python indicators with the community
- **Credit-Based Purchase**: Buy premium indicators from other users with credits
- **VIP Free Indicators** 🆕: Mark indicators as "VIP Free" — VIP members can use them without spending credits
- **Rating & Reviews**: Rate and review purchased indicators
- **Live Performance Tracking**: Real-time performance stats aggregated from backtests and live trades
### 6. Universal Data Engine
QuantDinger provides a unified data interface across multiple markets:

### 7. 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**: PostgreSQL database (shared with main data) or local files under `backend_api_python/data/memory/` (privacy-first).
