Hi,
We are seeing duplicate OrderID in the Book Message of type ADD in the same PDP Message [ same PDU].

this is first Book message of type ADD
MsgType = ADD_ORDER StockIndex = 6, OrderRefNo = 306585199, Side = B, Price = 172.69, Shares = 100, Exchange code = P, Session ID = 0,Source Seq No = 702198

Here is the second Book message of type ADD
MsgType = ADD_ORDER StockIndex = 6, OrderRefNo = 306585199, Side = B, Price = 172.69, Shares = 100, Exchange code = P, Session ID = 0,Source Seq No = 702207

As you can the message is same [except the Source Sequence No ].

How do we process this message? Should we assume that it replaces the previous order with this reference number?

Specs say -- > The Order ID identifies a unique order and will allow customers of NYSE Arca Trades to correlate trades to the order

Thanks,
Abhay
