I am having issues using the Trading Toolbox with Interactive brokers. I have tried this on two separate TWS/Matlab installations on two different machines, connected to two different IB accounts. Both connect to Excel via the TWS api/DDE without difficulty.
I have the latest TWS and api software installed. ActiveX socket clients and DDE are enabled in the TWS api settings. Trusted ip is set to 127.0.0.1. ibtws object seems to be created fine:
ibtws with properties:
Handle: [1x1 COM.TWS_TwsCtrl_1]
However, any attempt to retried data produces a 'not connected' error message in Matlab. For example: ib.Handle.createContract; ibContract.symbol = 'GS'; ibContract.secType = 'STK'; ibContract.exchange = 'NYSE'; ibContract.currency = 'USD'
>> getdata(ib, ibContract)
