Interactive Brokers API with Python and ib_async

Learn to use the ib_async Python library for simplified coding with the Interactive Brokers API through this 24-minute tutorial. Discover the fundamentals of asynchronous programming using a chess exhibition analogy to understand how concurrent operations work. Start by building a synchronous version for fetching historical data from Interactive Brokers, then observe the performance limitations when fetching data for multiple symbols sequentially. Transform your code into an asynchronous version using asyncio.run() and async def functions, implementing await statements with coroutines and tasks. Master the use of asyncio.gather() to fire off multiple coroutines simultaneously, dramatically improving performance when handling multiple symbols. Follow along with practical demonstrations that show the clear speed advantages of asynchronous programming over synchronous approaches, complete with source code and written tutorial resources for further learning.
