Hi guys,
I was testing out the trading toolbox with interactive brokers. I established the connection and tried to run the following code:
ib = ibtws('',7496)
ibContract = ib.Handle.createContract;
ibContract.symbol = 'AAPL';
ibContract.secType = 'STK';
ibContract.exchange = 'SMART';
ibContract.primaryExchange = 'NASDAQ';
ibContract.currency = 'USD';
startdate = floor(now) - 5;
enddate = floor(now);
d = history(ib,ibContract,startdate,enddate)
It returned:
ib =
ibtws with properties:
ClientId: 0
Handle: [1×1 COM.TWS_TwsCtrl]
Host: ''
Port: 7496
d =
'Unable to read beyond the end of the stream.'
Does anyone know why?

Please set the primaryExchange to 'SMART', they cannot be different from my testing. In some cases you need to run the command twice, becasue Matlab isn't accounting for the time needed for the API to connect to the historical data feed.
I am using Matlab 2019a: Trading Toolbox 3.5.1 & TWS Api 9.76
ib = ibtws('',4001, 0)
ibContract = ib.Handle.createContract;
ibContract.symbol = 'AAPL';
ibContract.secType = 'STK';
ibContract.exchange = 'SMART';
ibContract.primaryExchange = 'SMART';
ibContract.currency = 'USD';
startdate = floor(now) - 5;
enddate = floor(now);
d = history(ib,ibContract,startdate,enddate)

That’s right. SMART only works for stocks. Futures, bonds, etc you must specify the exact exchange.
