Problem running AccountSummaryExample #131

Open ladidalimey opened 3 years ago

ladidalimey commented 3 years ago

Hi, I have Matlab v R2019a and am using latest IB Gateway.

I get the following message...

AccountSummaryExample added interface method: TWSNotification notification listener has been added Server Version:76 TWS Time at connection:20210628 11:25:57 British Summer Time Undefined function or variable 'reqAccountSummary'.

Error in AccountSummaryExample (line 51) session.eClientSocket.reqAccountSummary(0,'All',attrkeys); pause(1);

Exception in thread "EReader": java.lang.AbstractMethodError: com.tws.Handler.orderStatus(ILjava/lang/String;IIDIIDILjava/lang/String;)V at com.ib.client.EReader.processMsg(EReader.java:251) at com.ib.client.EReader.run(EReader.java:70)

Please can you help.

Thanks

Thanks for asking. Can you try “older” version of TWS/gateway? Also please send output of “ver” command. Might just be new/most latest version of TWS might need update api version in IB4m.

I'm using Gateway 983 and everything works fine.
