OTC RFQs

The OTC Trading of TDX supports the RFQ trading flow. While the flow results in trades, it is substantially different from single orders and its usage in FIX is less mainstream, it is thus described in detail here.

Overview

In this integration the stream of quotes is initiated by sending a QuoteRequest (R) message. When a valid QuoteRequest is received, TDX begins streaming Quote (S) messages. A client accepts a quote by sending a QuoteResponse (AJ) message, and any resulting trade (or rejection) is reported via an ExecutionReport (8). Finally, a Quote Cancel (Z) message marks the end of the quote stream.

Quote Request

To request a stream of quotes, send a QuoteRequest message :

Tag	FieldName	Required	Data Type	Comment
	Standard Header	Y		MsgType = `R`
131	QuoteRequestID	Y	string	A globally unique identifier chosen by the client (a UUID v4 is recommended).
146	NoRelatedSym	Y	integer	Set to 1, indicating that one symbol (and its associated component block) follows.
55	Symbol	Y	string	The pair symbol for which quotes are requested (e.g. `ETH/USD`).
1	Account	Y	string	The client SubAccount that is trading, found in the TDX Client Profile
38	OrderQty	Y	decimal	The base quantity to be quoted at the preferred precision (e.g. `42.0000`, meaning 42 ETH).

Quote

The Quote message provides the details of each bid or ask :

Tag	FieldName	Required	Data Type	Comment
	Standard Header	Y		MsgType = `S`
117	QuoteID	Y	string	An encoded token to use when accepting this specific quote.
55	Symbol	Y	string	The pair symbol for which the quote is provided (e.g. `ETH/USD`).
54	Side	Y	char	Indicates the side: `1` (Buy, for an Ask quote) or `2` (Sell, for a Bid quote).
23432	OtcRfqID	Y	string	A UUID identifying this stream of quotes; must be repeated for any message that references this stream.
132	BidPx	Y	decimal	The proposed unit price, applicable for a Bid.
133	OfferPx	Y	decimal	The requested unit price, applicable for an Ask.
134	BidSize	Y	decimal	Same as the OrderQty from the QuoteRequest, repeated for ease of consumption.
135	OfferSize	Y	decimal	Same as the OrderQty from the QuoteRequest, repeated for ease of consumption.

Quote Response

To accept a quote from the stream, send a QuoteResponse message :

Tag	FieldName	Required	Data Type	Comment
	Standard Header	Y		MsgType = `AJ`
694	QuoteResponseType	Y	char	Must be set to `1` (Hit/Lift) to accept the quote.
693	QuoteResponseID	Y	string	A unique, client-provided id to identify this quote response
1	Account	Y	string	The sub-account used on TDX for trading (as in the QuoteRequest).
55	Symbol	Y	string	The pair symbol for which the quotes were requested (e.g. `ETH/USD`).
117	QuoteID	Y	string	The encoded token from the Quote that the client wishes to accept.
23432	OtcRfqID	Y	string	The UUID identifying the flow of quotes to which the accepted quote belongs.

Execution Report

After accepting a quote, TDX sends an ExecutionReport message that contains the trade’s outcome. While it is also present in normal order flows, the most relevant and RFQ-specific fields are repeated here :

Tag	FieldName	Required	Data Type	Comment
	Standard Header	Y		MsgType = `8`
150	ExecType	Y	char	`F` indicates that the quote acceptance resulted in a trade; `8` indicates rejection.
17	ExecID	Y	string	A UUID corresponding to the traded quote.
23432	OtcRfqID	Y	string	The UUID identifying the stream of quotes that generated this trade.
39	OrderStatus	Y	char	`2` (Filled) if traded, or `8` (Rejected) if not; provided for ease of integration and to show that quotes are fulfilled in one trade.
693	QuoteResponseID	Y	string	Repeats the QuoteResponseID provided by the client during acceptance.
11	ClOrdID	Y	string	Repeats the ClOrdID provided by the client during the quote acceptance.

Quote Cancel

When a quote stream terminates or is explicitly cancelled, the following message is sent:

Tag	FieldName	Required	Data Type	Comment
	Standard Header	Y		MsgType = `Z`
298	QuoteCancelType	Y	integer	Will be set to `4`, indicating “All Quotes”.
23432	OtcRfqID	Y	string	The UUID identifying the stream of quotes that is being terminated.
