Prime FIX 5.0 RFQ

Prime FIX 5.0 supports the complete request-for-quote (RFQ) flow for enabled spot accounts:

Send a QuoteRequest (R).
Receive a Quote (S) or a rejection through QuoteAcknowledgement (b).
Accept the quote with NewOrderSingle (D) before it expires.

RFQ messages support SecurityType=SPOT only. Quote requests must use a positive limit price and Fill or Kill time in force.

QuoteRequest (R)

Send a QuoteRequest to request an executable quote. Provide exactly one of OrderQty or CashOrderQty.

Tag	Name	Data Type	Req	Description
1	Account	String	Y	Portfolio identifier
131	QuoteReqID	String	Y	Unique client identifier for the quote request
55	Symbol	String	Y	Spot product identifier, such as `BTC-USD`
167	SecurityType	String	Y	Must be `SPOT`
54	Side	Char	Y	`1` = Buy `2` = Sell
40	OrdType	Char	Y	Must be `2` = Limit
59	TimeInForce	Char	Y	Must be `4` = Fill or Kill (FOK)
38	OrderQty	Qty	C	Positive quantity in base units. Required when CashOrderQty is not provided.
152	CashOrderQty	Qty	C	Positive quantity in quote units. Required when OrderQty is not provided. Availability is account-dependent.

8090	QuoteRequestGoodForMs	Int	N	Requested RFQ auction duration in milliseconds; maximum 30,000 ms, inclusive of the 250 ms LP quote window. Availability is account-dependent.

If both quantity fields are present, or if Price or the selected quantity is not positive, Prime rejects the request.

Quote (S)

62	ValidUntilTime	UTCTimestamp	Y	Time at which the quote expires
120	SettlCurrency	Currency	N	Settlement currency from the request, when provided

QuoteAcknowledgement (b)
