Is it inline with FIX protocol 4.2 to do corrects (20=2) on cancelled orders?

Yes. We can send Trade Corrections on Cancelled Orders but can not be send on Cancelled Execution Reports.
Look into the Example:-

  1. New Order Received from Client (35=D)
  2. Ack sent to Client (39=0 & 150=0)
  3. Partial Fill sent to Client (39=1 & 150=1)
  4. Order Cancelled (solicited/Unsolicited) (39=4 & 150=4)
  5. Trade correction on Partiall Fill (39=4 & 150=1), if you do the correction to change FilledQty equals to OrderQty then 39=2 & 150=2.

Hope this information helps you.
