Does FIX4.1/4.2 have any specs on execution reports for cxl/replace and cxl requests ? I am looking for a standard message sequence that a buy side should expect for cxl/replace requests.
The sequence of messages from exchanges/ECNs vary on cxl/replace and cancel messages.
Here are few examples from some ECNs:
Exchange I: (FIX 4.1)
MsgType OrderStatus ClntOrderID OrigClntOrdID
D - 101 -
8 0 101 -
G - 102 101
8 6 102 101
8 0 102 101
F - 103 102
8 6 103 102
8 4 103 102
Exchange II ( FIX 4.2)
MsgType OrderStatus ClntOrderID OrigClntOrdID
D - 101 -
8 0 101 -
G - 102 101
8 6 102 101
8 5 102 101
F - 103 102
8 4 102 101
Exchange III ( FIX 4.2)
MsgType OrderStatus ClntOrderID OrigClntOrdID
D - 101 -
8 0 101 -
G - 102 101
8 5 102 101
F - 103 102
8 4 103 102
Any ideas ?

Hi Sreedhar,
Both Fix 4.1 and Fix 4.2 documents include Order Cancel and Order Cancel Replace Matrixes in Appendix D. These appendices are accurate for what buysides should expect in the ClOrdID, OrigClOrdID, ExecType, and OrdStatus fields. But, as you noted, sellsides may or may not send the cancel/replace pending messages. In practice, these pending messages are effectively optional. Buyside implementations usually work either way. Some even ignore these pending messages altogether.

Michael,
Appendix D does not tell you what to expect in the ClOrdID, OrigClOrdID fields with respect to exec reports coming from sell sides.
I think the matrix should expand to show the values of ClOrdID, OrigClOrdID too in addition to other fields.
As you could see in my example, those values and how each message is
intrepreted is different in each case.
I would like to see atleast a standard way of populating ClOrdID, OrigClOrdID fields in this case.
Check out each example in case of OrdStat=4 - you will see that ClOrdID, OrigClOrdID are different.

Michael,
I was not reading the matrix properly - I see what you saying now.
The big problem is , ECN’s do not follow the matrix when it comes to
their FIX implementation as I mentioned in the example.
How do we enforce the FIX specs in this case ?

Sreedhar,
Unfortunately, we can not enforce FIX compliance. When a buyside wishes to connect to an ECN, they usually have to test with the ECN. No trading partner can expect to connect after saying “I’m FIX 4.X compliant”. They always have to test.
The main problem is that FIX versions leave a lot to interpretation. For example, FIX 4.1 does not specify what ClOrdID and OrigClOrdID the sellside should use after the first order change is accepted. Likewise, for FIX 4.2, one can argue that both your ECN II and ECN III scenarios demonstrate FIX compliance because the specification does not clarify which scenario is correct.
