Our company is splitting into two companies but would like to use our current order entry system and existing connections to ECNs. Does the FIX protocol address this or is this negotiated with each individual ECN? There are three terms in the FIX protocol; user id, account and firm. I think that firm (and therefore ClientId) is the closest concept to what we want to do. What is an account; a bank account, trader account or something else? The other option could be OnBehalfOf. The term "Service Bureau" is also in the FIX protocol but not defined anywhere.
