Problem getting data from ibtws

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)

No it does not work. Still got the same error: 'Unable to read beyond the end of the stream.'

[Annie Leonhart]

It works 100%.

proof it runs.... ran just now. https://i.imgur.com/mky2wbu.jpg

You also need to be subscribed to realtime data on IB. If you are not, it will NOT work.

You need these subscriptions on IBKR:

CBOE Realtime: $1/m

US Equity and Options Add-On Streaming Bundle: $4.50/m

US Securities Snapshot and Futures Value Bundle: $10/m

if you are missing any of those subscriptions, it will not work. IB does not allow you to pull historical data without a current realtime subscription. You cannot pull historical data using the snapshot bundle alone as it does not allow streaming.

Matlab 2019b: & TWS Api 9.76

I was having the same issue. I tried your example Annie and I got the same error as the others. I have all the required subscriptions. I had to use ib = ibtws('127.0.0.1',7496, 0) to get data

[John Quattrone]

Now it does not work so ignore my message

[John Quattrone]

What I have found is I have to restart MATLAB every time I want to run the script above. After the restart I can pull data. If I run it a second time I get

d =

'Unable to read beyond the end of the stream.'

[Annie Leonhart]

It’s because you need to close the connection at the end of the script.

Close(ib)

If you want to connect a second time without closing the connection, you must change the clientID

Hi Annie,

i still have the same problem. The connection to the TWS is established and verified. I also subscribed to market data from the German spot market (Spot Market Germany / Frankfurt). Maybe you can help me again?

Output: 'Unable to read beyond the end of the stream.'

ib = ibtws('',7496)

ibContract = ib.Handle.createContract;

ibContract.symbol = 'WDI';

ibContract.secType = 'STK';

ibContract.exchange = 'SMART';

ibContract.primaryExchange = 'IBIS';

ibContract.currency = 'EUR';

startdate = floor(now) - 5;

enddate = floor(now);

d = history(ib,ibContract,startdate,enddate)

close(ib)

[Sandro Hantke]

Annie,

I just solved the problem! IBContract.exchange=IBIS

[Annie Leonhart]

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