Why am I encountering unrecognized property 'expiry' error while accessing the contact data?

Why am I encountering unrecognized property 'expiry' error while accessing the contact data?

I am trying to create a contract and get the Interactive Brokers data, but I am encountering the following error messages for the below code snippet:

>> ibs = ibtws('',7496);

>> pause(1);

>> ibContractData = ibs.Handle.createContract;

>> ibContractData.symbol = 'EUR';

>> ibContractData.secType = 'FUT';

>> ibContractData.exchange = 'GLOBEX';

>> ibContractData.expiry='201806';

>> ibContractData.currency = 'USD';

>> rtd=getdata(ibs,ibContractData)

>> close(ibs);

Unrecognized property 'expiry' for class 'Interface.AE6A66F3_8FA9_4076_9C1F_3728B10A4CC7'.

Error in Untitled (line 9)

ibContractData.expiry='201806';

You are encountering the error messages because there is no "expiry" property for the "ibContractData".

To resolve this issue, you need to use the property "LastTradeDateOrContractMonth" as follows:

>> ibContractData.LastTradeDateOrContractMonth = '201806';

IB renamed the Expiry property to "LastTradingDay" or "LastTradeDateOrContractMonth" (depending on the specific use-case) in its API release 9.72 (use with TWS version 959 or higher): https://www.interactivebrokers.com/en/index.php?f=23565#972-10
