Hi,

You can ignore this "error".
At the beginning, IB plugin tries to request account data for the regular account.
In a case of FA, TWS reports an error and then IB plugin uses MonitoredAccount.

I am still not able to connect, May be other modification IB made is not compatiable wth OQ. I am able to connet to my sim FA account, but the live FA account does not work.

Hi,

Could you enable logging of IB plugin, try to connect and send me plugin's log file (ib-yyyyMMdd.txt)
from the <%appdata%>\SmartQuant Ltd\OpenQuant\Framework\logs directory.

Hi,

stephen_mcse: did you manage to resolve this?

I have the exact same issue after updating IB TWS and IB Gateway today.
IB forces their customers to update to TWS version 940 or above before May 1, 2014 and we received the notice a couple of days ago.
So today between 5.00 pm and 5.15 pm (when their FX platform IDEALPRO is closed) I updated IB TWS/Gateway and restarted it.
When I try to connect to our FA account, I get the same error message: "The account code is required for this operation."
There are potentially sensitive data in the IB plugin log so I'll send them as a private message.

Their API support told me this today:
"Angel P: there should not be any changes from the client program side, you may need to check to see if you are getting any error( ) event
Angel P: no I did not receive any reports of customers having issues with OpenQuant. In this case it is feasible they may not support the latest build of have some issues with there program. I would advice to contact them directly for additional assistance"

EDIT: the Provider Errors panel also displays issues regarding System.Xml which I guess may have been triggered within the IB Plugin when it tries to parse and analyse FA allocation profile XML data from IB. Maybe IB has changed something to their format and IB Plugin isn't able to interpret the XML string anymore, crashes and therefore disconnects from IB. Just a guess...

Code:
System.Xml.XmlException: Data at the root level is invalid. Line 1, position 1.
   at System.Xml.XmlTextReaderImpl.Throw(String res, String arg)
   at System.Xml.XmlTextReaderImpl.ParseRootLevelWhitespace()
   at System.Xml.XmlTextReaderImpl.ParseDocumentContent()
   at System.Xml.XmlLoader.Load(XmlDocument doc, XmlReader reader, Boolean preserveWhitespace)
   at System.Xml.XmlDocument.Load(XmlReader reader)
   at System.Xml.XmlDocument.LoadXml(String xml)
   at quDd0dfw9hGDWoyf71.IHv22ej3VMJHXGFwZQ.SAAICsttil(String )
   at SmartQuant.IB.IBTWS.YexCOocNUV(MsgReceiveFA )
   at SmartQuant.IB.IBTWS.IH4Cq9pAbE(ThMEepH8hD3Y6fdfXw )
   at LrlrT1TeKMCTQVThRH6.oAx9l5T9ostlqAFxHNO.lAUxM332cv()

FYI I just managed to revert back to a previous version: "Build 939.4b, Apr 23, 2014 2:30:36 PM" which I got by clicking on "Upgrade" here https://www.interactivebrokers.com/en/index.php?f=674
I'm pretty confident that IB has changed their allocation profile XML format and that OQ's IB plugin crashes because it's not up to date.

This is extremely urgent since on May 1, 2014, all versions below 940 will be discontinued.

Alexei, I've sent you all relevant data via PM.

Thanks for your help!

Here is what IB support told me based on logs I sent them:

Quote:
According to the log's it seems that OpenQuant is attempting to invoke the reqFA( ) and is unable to load the associated Account Aliases (faDataType = 3) which seems to be associated with the disconnect you are experiencing, please refer to the details in the log below:

I have seen similar customer have issue in the past but seems to have been associated with an issue with there settings. As a test in the chat I had advised to please see if you have the same issue using the "Browser Based IB Gateway Beta" which can be accessed from the following URL:

https://www.interactivebrokers.com/en/s ... ftware.php

It seems the chat was disconnected before I received a response. Please reply back via e-mail if you have the same issue when using the Beta Version of the IB Gateway from the above URL.

Regards,

Hi All,

There is a problem with receiveFA(int faDataType, String xml) function of IB API.
By some reason, TWS sends not well-formed xml data.
PBJ, please look into the bottom of log file you sent me.
There are two correct messages like:
<FaDataType type="System.Int32">1</FaDataType><Xml type="System.String"> ?xml version="1.0" encoding="UTF-8"?
But the last line contains invalid xml:
<FaDataType type="System.Int32">3</FaDataType><Xml type="System.String">4</Xml>

The very strange thing is we do not get invalid xml when using fdemo/demouser login.

Ofcourse, we can handle an exception from xml parser and ignore it, but it seems that the IB plugin will not receive correct account data in this case.

I sent these comments to IB. If you could provide your email address, it would be more efficient to communicate.

I also tried what Angel suggested, using Browser Based IB Gateway Beta: the problem is the same.
