IBKR TWS API for C# Programmers

Did you know that C# has consistently been ranked one of the top programming languages? It is also a desired skill by Wall Street employers. Therefore, consider IBKR C# API educational resources for writing your algo trading strategies in this programming language.

GitHub Resources


First, let’s explore our GitHub Guide. For instance, review the Connectivity and contract detailed examples, and learn how to initially set up TWS. After that, dive into the syntax for streaming market data, setting up scanners and error handling. In addition, the historical market data portion of the guide will help you find the earliest date historical data is available for an instrument, which is important for backtesting your algo strategies. Finally, wrap up the review with a look at the Classes list, such as EClient and EWrapper.


Demonstration of C# API Architecture

In addition to our GitHub, watch this popular step-by-step demo to fully experience the API features built in C#. Our API team starts the presentation with an Overview of TWS API capabilities and requirements. Next, learn the Architecture of the C# API from a development perspective. The presenter also shows a Typical flow of API programs with ‘Testbed’ and ‘IBSampleApp‘ examples. Next, take a look at how the API expert uses Github API guide for reference. At the end of the demonstration, our API expert codes important functions to perform tasks such as placement of advanced order types.
