OrderType for Executable Streaming Price model

Imported from previous forum

I have a situation where I am streaming tradeable prices to a client application. If/when a price is accepted, I would like to receive a New OrderSingle message (with the accepted price on it) and essentially “fill” it at the accepted price. There will not be any fills at a different price and nor would I maintain any standing orders (therefore either a Fill or Reject Execution rpt would be returned)

Given, this what would be the most appropriate OrderType, TimeInForce (and HandlInst) values on the NewOrderSingle message ? (What sort of order is this). Essentially the fill would be by the broker/dealer and there is no other routing to any other market place and this would be specific to FX.

Thanks

The most appropriate OrderType would be previously quoted (40=D),
If you support Partial fills TimeInforce would be IOC (59=3) if not FOK (59=4) and HandlInst Automated execution order (21=1).
Hope this helps.
