BY IOC i beleive you mean to say in 35=6 value of TAG 28=C , if this is the case all the brokers who sends IOI Transaction Type 28=N sends this.

IOI is basically sends by Brokers only to ask for the interest from their clients to show what orders they can fill up , asking for their interest.

and in case that order exec is gone from the brokers side they have to send the cancellation of the previous new IOI . TAG 26 is required to show up the new IOI sent.

Hi  
From my understanding, the initial question is about sending IOC orders for IOI’s. Which I have come across with NYFIX, they provide their clients with an option to send IOC’s in response to IOI’s. They call these IOI’s as IOL’s (Indication of Liquidity) since its on their exchange. They must be aware of their clients (Brokers and Vendors ) who provide similar service for IOI’s.
