longbridge
A Python library for Longbridge Open API
Decision gist · record as of 2026-08-14
Yes, with conditions. Longbridge is actively maintained, has no known vulnerabilities, and offers a comprehensive API surface for trading and market data. However, the unclear license status is a blocker for commercial use—verify licensing terms in the repository before deploying in proprietary projects. Install friction is moderate due to compiled wheels, but this is typical for performance-critical financial libraries. Suitable for retail traders, fintech developers, and market data consumers with Longbridge account access.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires OAuth client registration or legacy API key credentials (LONGBRIDGE_APP_KEY, LONGBRIDGE_APP_SECRET, LONGBRIDGE_ACCESS_TOKEN environment variables).
- Python >= 3.8 required.
- Medium install friction due to compiled wheels across multiple Python versions and platforms (cp310–cp312, macOS, Linux, Windows).

What it is and what it does
Longbridge is a Python SDK that wraps the Longbridge OpenAPI, a financial data and trading platform. It provides synchronous and asynchronous interfaces to multiple specialized contexts: QuoteContext for real-time quotes and candlesticks, TradeContext for order and position management, FundamentalContext for financial reports and analyst ratings, MarketContext for market status and holdings, and several others for calendar data, alerts, and portfolio analysis. The package is built with Rust bindings for performance and supports OAuth 2.0 authentication as the recommended method, with legacy API key support available.
The SDK is designed for developers building trading applications, market analysis tools, and portfolio management systems. It handles WebSocket subscriptions for push data, supports both synchronous and asynchronous workflows, and includes configuration management for multiple environments and language settings. Zero runtime dependencies keep the install footprint minimal.
Use it for
- Build a real-time stock quote dashboard that subscribes to price updates and displays candlestick data for multiple securities.
- Automate order submission and monitor execution status, positions, and account balance across trading sessions.
- Retrieve financial reports, analyst ratings, and dividend information for fundamental analysis and valuation workflows.
- Implement price alerts and manage watchlists programmatically for custom trading workflows.
- Analyze portfolio P&L using exchange rates and portfolio context APIs for multi-currency portfolios.
- Fetch financial calendar events (earnings, splits, IPOs) to schedule market analysis or trading strategies.
