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

Hi all,

I recently purchased the trading toolbox and I've been following the tutorial on how to obtain historical market data but I always get his error message

'Unable to read beyond the end of the stream.' Hope someone can help.

Here is my code

ib = ibtws('',7497);

ibContract = ib.Handle.createContract;
ibContract.symbol = 'MSFT';
ibContract.secType = 'STK';
ibContract.exchange = 'SMART';
ibContract.currency = 'USD';
 
bdc = 13;

startDate = daysadd(today,-20,bdc);
endDate = daysadd(today-1,-1,bdc);

You need to be subscribed to realtime data on IB.

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

Thank you, Annie!

Let me know if the problem persists after subscribing to the required datafeeds

ib = ibtws('',7496);

ibForex = ib.Handle.createContract;

ibForex.symbol = 'CL';

ibForex.secType = 'FUT';

ibForex.primaryexchange = 'NYMEX';

ibForex.exchange = 'SMART';

ibForex.currency = 'USD';

ibForex.LastTradeDateOrContractMonth ='20200421';

startdate = floor(now)-1;

enddate = floor(now);

barsize = '1 min';

ticktype = 'BID';

d = history(ib, ibForex, startdate, enddate, barsize, ticktype)

Hello I have the same problem, and I have already signed up NYMEX Real-Time data, but still getting the same error mesage. Please help, thank you.

Change exchange to match the primary exchange

[Allen Lee]

i tried that, but it runs afterward, but matlab is stuck in busy for a long time and not return anything.

Any idea why this is happening?

[Annie Leonhart]

How long is a long time?

[Allen Lee]

it just wont stop unless i force stop it,

i tried to change the bar size to 8 hours, so that it will fetch less data.

but still, the code wont stop

[Annie Leonhart]

ib = ibtws('',7496);

ibForex = ib.Handle.createContract;
ibForex.symbol = 'CL';
ibForex.secType = 'FUT';
ibForex.primaryexchange = 'NYMEX';
ibForex.exchange = 'NYMEX';

ibForex.LastTradeDateOrContractMonth ='202004';
startdate = floor(now)-1;
enddate = floor(now);
barsize = '1 min';
ticktype = 'BID';

d = history(ib, ibForex, startdate, enddate, ticktype, barsize)

Try this.

If this doesn't work, you should download and use the IB Gateway and turn the log on. Then when you run it, you can see what it's doing and I can better see what's going on :)

[Allen Lee]

ib = ibtws('',7496);

ibForex = ib.Handle.createContract;

ibForex.symbol = 'CL';

ibForex.secType = 'FUT';

ibForex.primaryexchange = 'NYMEX';

ibForex.exchange = 'NYMEX';

ibForex.LastTradeDateOrContractMonth ='20200421';

startdate = floor(now)-1;

enddate = floor(now);

barsize = '1 min';

ticktype = 'BID';

d = history(ib, ibForex, startdate, enddate,ticktype, barsize)

i tried this and it finally worked. thanks
