## Introduction
VeighNa (formerly vnpy) is a Python-based quantitative trading platform that originated in the Chinese financial technology community. It provides a modular architecture for developing, backtesting, and executing automated trading strategies across multiple asset classes including equities, futures, options, and crypto.

## What VeighNa Does
- Supports live trading connections to Chinese and international brokers and exchanges
- Provides a desktop GUI for strategy monitoring, order management, and portfolio tracking
- Includes backtesting and optimization engines for evaluating strategy performance
- Offers modules for spread trading, options pricing, and portfolio management
- Supports CTA, market-making, arbitrage, and algorithmic execution strategies

## Architecture Overview
VeighNa uses an event-driven architecture centered around an EventEngine that dispatches market data, order, and trade events to registered handlers. Gateway modules abstract broker/exchange connectivity, while app modules provide specialized trading functionality. The platform uses a plugin system that lets traders mix and match components.

## Self-Hosting & Configuration
- Install the core framework via pip with optional gateway packages
- Configure broker connections through the GUI or JSON configuration files
- Deploy strategies as Python classes registered with the CTA engine
- Run on Windows or Linux with Python 3.10+
- Use Docker for headless server deployments in production

## Key Features
- Event-driven architecture for low-latency order routing and data processing
- Gateway adapters for dozens of Chinese brokers and international exchanges
- Built-in risk management with position limits and order flow controls
- Real-time charting and indicator display in the desktop interface
- Large community with extensive Chinese-language documentation and tutorials
