Prerequisites
Microsoft Office Excel (Windows Only)
Java Runtime Environment (JRE)
Before we begin, there are some prerequisites the TWS API requires. For example, if are looking to use our excel APIs, you would need Java and a Windows copy of Microsoft Excel installed.
Overview of the TWS API
The Interactive Brokers' TWS APIs allows other applications and programs to work with the Trader Workstation (TWS) or IB Gateway. Trader Workstation is our flagship trading platform and IB Gateway is the lightweight version without any of the manual trading features.
In this course, we will cover connecting Microsoft Excel to TWS so we can retrieve market data, place orders, view account and portfolio data and much more! We'll explore a sample spreadsheet that has been created by IBKR to highlight the functionality of the Excel TWS API. You can reference the sample spreadsheet as we show you examples in this course. We'll also cover making an API request, such as retrieving market data, using a blank Excel spreadsheet. This way you'll know how to connect your existing spreadsheet with TWS.
Let's briefly cover the TWS API a bit more in depth, and its capabilities.
Downloading and installing TWS
Before we get started, make sure you have TWS or IB Gateway installed, If you don't, you can head over to our website, ibkr.com, select “Log In” in the upper right hand corner of the page and from the drop down menu, select Trader Workstation or API: IB Gateway.
They can also be found on our main website, under the menu Trading, then Platforms.
In addition, there are some prerequisites the TWS API requires. For example, if are looking to use our excel APIs, you would need Java and a Windows copy of Microsoft Excel installed.
The latest version of our Excel APIs are supported with both 32-bit and 64-bit Operating Systems. However, they are not compatible with the Mac Operating System. Our website will automatically provide a download version but you may choose a different version if you'd like.
Installing the TWS API
To obtain all the components required to use the Excel APIs, including sample sheets and source code, on our website, you may navigate to ibkr.com and access the menus at the top and select Trading > APIs and select Download and Resources.
Our APIs are provided with a Non-Commercial license agreement. You may download either the stable or latest version.
Note, the Excel APIs are only supported for the windows operating system. The most up-to-date version of Interactive Brokers API source code is hosted on Github as a private repository. We refer to this as our “beta client” although it doesn't use formal release numbers as do our “Latest” and “Stable” API versions.
This code is frequently updated with new features and functionality, and periodically the API source code in this private repository is published as a new version of API Latest. Users can gain access to the Github repository to view the current Beta API source code as well as to contribute suggestions and source code.
Our goal in allowing our users to contribute is to improve the reliability and versatility of the API for everyone. Review this page if you’d like to access and contribute to the API Beta version.
After successfully installing, you will find the API samples and components installed on the same drive as the operating system which is usually the c drive.
- Here you'll see the folders samples, source, source, and tests.
- The source folder contains the necessary files to create your own API application, and in essence define the available messages the API can send and receive.
- In this course, we will discuss the content from the samples folder, which contains the sample spreadsheets for DDE, ActiveX, and RTD inside the “Excel” folder.
- The DdeSocketBridge folder inside samples contains the batch file necessary to run the new DDE sample. We'll cover this more later. Also note, the tests folder contains the library TwsLib.dll , which is used by the ActiveX sample.
Configuring TWS Settings for API
TWS is required to be open on your computer to integrate with Excel. Just double click on the Trader Workstation desktop icon to launch and log into TWS.
Now that TWS is running, let's enable the API functionality. Go to the menu at the top of TWS and select Edit > Global Configuration > API > Settings, and then check the box on the left Enable ActiveX and Socket Clients.
By default, the sample sheet that we'll use port 7496 so you'll see that set here. When done click on Apply and then click on Ok.
Now that we have TWS configured, the next video in this course will go over using Excel RTD, which stands for real time data. Hope you can join us!
There is no obvious path to the next video with how to set up excel.
Hello, thank you for reaching out. If you scroll back to the top of the page, on the right-hand side by the number 2, you can access the next course. It is called “Using RealTimeData (RTD) server for Excel” where more instructions will be provided to set up excel. We hope this helps.
How can I access the account data (positions, margins used, Open P/L, etc.) using RTD?
Hello Ettore, thank you for reaching out. Please view this Campus lesson for more information about using RealTimeData(RTD): https://www.ibkrcampusdev.wpengine.com/campus/trading-lessons/using-realtimedata-rtd-server-for-excel/

but i don’t know how to make the RTD chart with that data, maybe need extra file or software?
Hello, thanks for asking. You are welcome to implement Excel’s chart system directly; however, Interactive Brokers does not support customized implementations such as charting through Excel. As a result, Interactive Brokers API Support would be unable to assist you in this endeavor. If you are in need of additional support, please create a web ticket for this inquiry; we have a category specifically for “API.” One of our API experts will be happy to guide you! https://www.interactivebrokers.com/sso/resolver?action=NEW_TICKET
Hi, I’ve just downloaded the last API version and playing with the Excel RTD example file. While it works for Europe market it doesn’t for US ones. I’ve got the message “Request Market Data is not subscribed. Displaying delayed market data”. After checking my Market Data Subscription setting, both markets are fee waived.
Any help will be much appreciated.
Hello, thank you for reaching out. It is not compulsory to subscribe to market data.
https://www.interactivebrokers.com/en/pricing/research-news-marketdata.php
Some exchanges allow delayed data to be displayed without any market data subscription, free of charge. Customers receive free delayed market data for contracts to which they do not currently hold market data subscriptions when made available by the exchanges. Delayed market data is on a time lag that is usually 10-20 minutes behind real-time quotes. You can read more here:

Feel free to consult the IBKR Market Data Assistant to find the best market data for your needs.
