I've just received this communication from Interactivebrokers:
Dear Client,
You are receiving this communication as we have identified your account UXXXX696 as one that is submitting orders via an API (either your own software or third party application) and using a TWS version that is substantially outdated and scheduled to be decommissioned for API purposes effective May 1, 2014.
Effective May 1, 2014, TWS versions below 940.0 will no longer be operable for API use, but will remain operable for non-API generated orders. It’s important to note that if you are integrating a third party software application (charting, order entry, analytical, etc.) with the TWS, you are doing so through the API and must upgrade if you wish to continue using that application.
To repeat, if you are receiving this notice and intend to continue using an API for order submission, you must upgrade your TWS version and the deadline for doing so is prior to May 1, 2014.
Should you have any questions regarding this matter, please contact your local Customer Service Center.
Technical Service Team
TWS 938 1e Abr22, 2013
So I need urgently to know which TWS version can actually work properly
Thanks
