L.1.a — Transmitting a guarantee of execution prior to execution (Stopped/Guarantee)

Time	Message Received (ClOrdID, OrigClOrdID)	Message Sent (ClOrdID, OrigClOrdID)	Exec Type	OrdStatus	Order Qty	Cum Qty	Leaves Qty	Last Qty	Comment
1	New Order(X)				10000
2		Execution(X)	Rejected	Rejected	10000	0	0	0	If order is rejected by sell-side (broker, exchange, ECN)
2		Execution(X)	New	New	10000	0	10000	0
3		Execution(X)	Stopped	Stopped	10000	0	10000	1000	Text="You are guaranteed to buy 1000 at 50.10"; LastPx=50.10. This is similar to the concept of a "protected" trade. Not actually reporting a trade, so Exectype = Stopped
4		Execution(X)	Trade	Stopped	10000	1000	9000	1000	LastPx=50 * executed price is better than guaranteed
