Error Connecting to IB using ibtws

Hi guys,

I'm having a bit of trouble connecting to the IB Trader Workstation using the Trading Toolbox command ibwts. I've found a few other questions that were left unanswered but if anyone can help out it would be much appreciated. A bit of information:

TWS Build: 949.3a -- Enabled ActiveX & Socket Clients

API Version: 9.71

Matlab R2014b

Windows 8.1, 64 bit

Below is the code and error I receive. Thanks for any help.

ib = ibtws('',7496)
---------
Error using feval
Server Creation Failed: The application has failed to start because its
side-by-side configuration is incorrect. Please see the application event log or
use the command-line sxstrace.exe tool for more detail.

Error in actxserver (line 86)
        h=feval(['COM.' convertedProgID], 'server', machinename, interface);

Error in ibtws (line 38)

This problem is due to using the ActiveX connector to IB.

You might wish to try the cross-platform Java-based approach (not ActiveX) of the IB-Matlab product: http://undocumentedmatlab.com/ib-matlab

Seriously? Isn't there a solution that doesn't cost 400 dollars? This is ridiculous.

You have incompatible library files installed.

I have managed to solved this by installing the 32 bit Version of “ Microsoft Visual C++ 2005 Redistributable ”. Here more information on how to link Matlab to IB TWS.

I have found the solution. I am using R2019a x64 on Windows 10. It may work for previous versions.

1. Install latest "stable" API from Interactive Brokers. Link Here
2. Install IB Gateway. Link Here
3. Install both x86 and x64 Visual C++ from Microsoft. Link Here
4. It'll make you reboot your PC.

Run IB Gateway and connect. Note the "Socket port" of the gateway through Configure > Settings > API > Settings

Run the following code and you should be connected.

ib = ibtws('127.0.0.1', 4001,1) % Change the port to your IB Gateway or Workstation port

% Create IB contract
ibContract = ib.Handle.createContract;
ibContract.symbol = 'IBM';
ibContract.secType = 'STK';
ibContract.exchange = 'SMART';
ibContract.primaryExchange = 'IEX';
ibContract.currency = 'USD';

format bank
d = getdata(ib,ibContract) % Return market data

I am using 2020b version of matlab, using:

ib = ibtws('127.0.0.1', 4001,1)

gives an error saying you need the trading toolbox, however matlab have changed the trading toolbox to the datafeed toolbox and financial toolbox which don't have any features to send requests to interactive brokers.

Any solutions??
