Hi,
Does anyone know of any informaton resource which has information asto how to get FIX EXTENDED?
Currently, I am faced with a situation in which I am not finding any standard FIX message to convey "Get Portfolio" "Get Offerings" messages.
Please tell me of ANY resource you know of, which might be of help.

Thanks in anticipation.

Generally, the way this works is one of two ways:

  1. You spec out the purpose, what you need, and how to accomplish it and provide that to the Technical Committee for consideration as a proposed change.
  2. There is enough interest from various firms to establish a working group to produce #1.

The litmus test as to whether or not such changes are seriously considered for future releases of the protocol is whether or not they apply and benefit multiple firms. For example, some features may apply to more than one trading facility (i.e. ECN), however, others may be very specific to one trading facility eventhough multiple firms communicate with that stock exchange. The former would be considered, the later may be recommended to be implemented in a user-defined manner.

We have a range of tag numbers which can be used for user defined fields and a way to use user-defined messages, however, I would recommend that you pursue #1 or #2 above.

Hi
May one place user-defined fields inside a standard fix message? Would that message still be considered well-formed ?
