# ib_async
## Update
## Introduction
`ib_async` is a Python library that provides a clean, modern interface to Interactive Brokers' Trader Workstation (TWS) and IB Gateway. It handles the complexities of the [IBKR API](https://ibkrcampus.com/ibkr-api-page/twsapi-doc/) so you can focus on building trading applications, research tools, and market data analysis.
### What You Can Build
* **Market Data Applications**: Stream live quotes, historical data, and market depth
* **Trading Systems**: Place, modify, and monitor orders programmatically
* **Portfolio Tools**: Track positions, account balances, and P&L in real-time
* **Research Platforms**: Analyze contract details, option chains, and fundamental data
* **Risk Management**: Monitor exposures and implement automated controls
### Key Features
* **Simple and Intuitive**: Write straightforward Python code without dealing with callback complexity
* **Automatic Synchronization**: The [IB component](https://ib-api-reloaded.github.io/ib_async/api.html#module-ib_async.ib) stays in sync with TWS/Gateway automatically
* **Async-Ready**: Built on [asyncio](https://docs.python.org/3/library/asyncio.html) and [eventkit](https://github.com/erdewit/eventkit) for high-performance applications
* **Jupyter-Friendly**: Interactive development with live data in notebooks
* **Production-Ready**: Robust error handling, reconnection logic, and comprehensive logging
Be sure to take a look at the
[notebooks](https://ib-api-reloaded.github.io/ib_async/notebooks.html),
the [recipes](https://ib-api-reloaded.github.io/ib_async/recipes.html)
and the [API docs](https://ib-api-reloaded.github.io/ib_async/api.html).
## Installation
```
pip install ib_async
```
Requirements:
- Python 3.10 or higher
- We plan to support Python releases [2 years back](https://devguide.python.org/versions/) which allows us to continue adding newer features and performance improvements over time.
- A running IB Gateway application (or TWS with API mode enabled)
- [stable gateway](https://www.interactivebrokers.com/en/trading/ibgateway-stable.php) — updated every few months
- [latest gateway](https://www.interactivebrokers.com/en/trading/ibgateway-latest.php) — updated weekly
- Make sure the [API port is enabled](https://ibkrcampus.com/ibkr-api-page/twsapi-doc/#tws-download) and 'Download open orders on connection' is checked.
- You may also want to increase the Java memory usage under `Configure->Settings->Memory Allocation` to 4096 MB minimum to prevent gateway crashes when loading bulk data.
The ibapi package from IB is not needed. `ib_async` implements the full IBKR API binary protocol internally.
