When I try to use the 'ibtws' class in MATLAB R2014a to access data from the Interactive Brokers (IB) Trader Workstation , for instance if I am trying to run the following example function 'timeseries', I get the following error:

No method 'reqHistoricalDataEx' with matching signature found for class 'COM.TWS_TwsCtrl_1'.

Error in ibtws/timeseries (line 101) c.Handle.reqHistoricalDataEx(1,s,endDateTime,durationString,barsize,ticktype,0,1)

My code is as follows, how can I fix this? Thanks

IB = ibtws('',7496); ibContract = IB.Handle.createContract; ibContract.symbol = '700'; ibContract.secType = 'STK'; ibContract.exchange = 'SEHK'; ibContract.currency = 'HKD';

startdate = floor(now-3); enddate = now; barsize = '5 mins'; Test = timeseries(IB,ibContract,startdate,enddate,barsize);
