Tags 207 and 100 have different meanings/semantics. 207 SecurityExchange further identifies the instrument. If you change it you are saying that you want to trade a different instrument with the same order, does not really make sense. 100 ExDestination says where you want the order to execute. Changing it changes the marketplace. Seems strange to allow a modification of this value as the marketplace itself will certainly not accept it (it would have to "route" your order there, can't really imagine that). A broker in between could obviously have tried your order in one place and then in another, informing you about the change. In my view, that would require you to have left tag 100 open, leaving it up to the recipient to choose the proper marketplace. If you send tag 100, there should be no unsolicited modification of its value. You should be the only (if allowed) to change it. Typically, it is not allowed and you need to cancel the order and re-issue a new one. Regards, Hanno. > Hi, In 35=D, 207=XX, 100=XX.
