Post From: Notice: Important Update for Interactive Brokers Users

A couple of additional points we want to make. The particular field that Interactive Brokers requested us to use in the contract details to determine the Year and Month for a futures contract, was not even documented and did not have a complete name to it. So it was never clear to us that that field was even available.
Furthermore, a similar case to this was discovered with CTS T4, but did not cause any problems because it only involved spread symbols which do not have Positions reported for them anyway. Only the individual legs are reported.
When we pointed this out to CTS, they explained that they provide the security definition data before the Positions are sent upon connection to the FIX server so there is no need to do a lookup of the security definitions for the current Positions or open Orders, and re-request the Positions and Orders and then apply the security definition data to get the correct Symbol.
So CTS recognizes that it is necessary to automatically provide the client proper security definition data for all symbols for which there are open orders and Positions ahead of sending that trading data. But Interactive Brokers does not recognize this.
We will openly state, that Interactive Brokers needs to do a much better job with there API. They are welcome to post their comments here. But so far we have heard no proper solutions from them. Only various explanations on how to deal with their interface to begin with. There are no proper solutions from them. And the user suffers.
