The new order message type is used by institutions wishing to electronically submit securities and forex orders to a broker for execution.

Orders can be submitted with special handling instructions and execution instructions. Handling instructions refer to how the broker should handle the order on its trading floor (see HandlInst field). Execution instructions contain explicit directions as to how the order should be executed (see ExecInst field).

New Order messages received with the PossResend flag set in the header should be validated by ClOrdID and order parameters (side, symbol, quantity, etc.) to determine if the order had been previously submitted. PossResends previously received should be acknowledged back to the client via an Execution - Status message. PossResends not previously received should be processed as a new order and acknowledged via an Execution - New message.

The value specified in the TransactTime field should allow the receiver of the order to apply business rules to determine if the order is potentially "stale" (e.g. in the event that there have been communication problems). To support forex accommodation trades, two fields, ForexReq and SettlCurrency, are included in the message. To request a broker to execute a forex trade in conjunction with the securities trade, the institution would set the ForexReq = Y and SettlCurrency = “intended settlement currency”. The broker would then execute a forex trade from the execution currency to the settlement currency and report the results via the execution message in the SettlCurrAmt and SettlCurrency fields.

The order message can also be used to request a straight forex trade. Conventions for identifying a forex transaction are as follows:

• The forex Symbol is defined in "EBS" (Electronic Banking System) format: "CCY1/CCY2".
• Rates are expressed as "currency1 in currency2" (or "currency2 per currency1") and are calculated as CCY2 divided by CCY1 (NOT CCY1 divided by CCY2)
• (e.g. "GBP/USD" represents a rate expressed as USD per GBP, "USD/JPY" represents a rate expressed as JPY per USD, etc.).
• CCY1 and CCY2 are ISO currency codes
• The value of the Currency field represents the denomination of the quantity fields (e.g. JPY represents quantity of JPY).
• In the case of a Forex - Swap (buying (or selling) a currency at one value date and selling (or buying) the same currency at a different value date), Side should represent the side of the FutSettDate2 transaction.
• OrdType = Forex - Market, Forex - Limit, Forex- Swap, or Forex - Previously Quoted
• Netting can be specified via the ExecInst field.
• See Appendix O – Foreign Exchange Trading

Orders involving or requiring Pre-Trade Allocation consist of the following steps:

• Buyside sends a New Order request message specifying one or more AllocAccount and AllocShares values within the repeating group designated by NoAllocs.
• Sellside sends Execution Report messages for the “New” and resulting fills.
• Post-Trade Allocation messaging takes place

To “take” an IOI (or Quote) from an ECN or exchange and not display the order on the book, the New Order message should contain the TimeInForce field with ImmediateOrCancel and an OrdType field with Previously Indicated ( or Previously Quoted).

The presence of DiscretionInst on an order indicates that the trader wishes to display one price but will accept trades at another price. For example a sell order with OrdType = Limit, Price=50.00, DiscretionInst = Related to displayed price and DiscretionOffset = -0.25 means that the order should be displayed as an offer for 50.00, but will match any bid >= 49.75 Discretionary pricing can also be used when pegging an order - for example to indicate that a buy order is to be displayed as pegged to the bid minus 0.25, but can be matched by anything <= the offer, set OrdType=Pegged, ExecInst = Primary Peg, PegDifference = -0.25, DiscretionInst = Related to market price and DiscretionOffset = 0.
