hi,

i'm trying to connect matlab to intercative broker, but when i use this command : ib = ibtws(‘ ‘,7496); command does not cause the TWS authorization window to pop up.

i have the latest TWS and the latest software API, i enable the activex and socket client. what i have to do?

在 MATLAB Online 中打开

There is no authorization box that comes up. You're connected with localhost which is already allowed.

I would also recommend IB Gateway rather than TWS as it will tell you the status of the connection and will return api outputs to the window and MATLAB. Very good if you wish to troubleshoot API calls.

IB Gateway Download

You can test the IBTWS connection with:

ib.Handle

it should return COM.TWS_TwsCtrl. If it does, it's successfully connected to the ActiveX object.
