Details

Note

title	Mandatory Fields

OrderOriginationTrader must be populated with OEOID for NDFs:

OEOID ("Order Entry Operator ID") and will be required for all NDF Quote messages from Makers, and all NDF NewOrderMultileg, MultilegOrderCancelReplaceRequest and OrderCancelRequest messages from Takers. Please send your OEOID as the PartyID for PartyRole OrderOriginationTrader. Cboe will reject NDF messages that do not populate OEOID.

Settlement and MaturityDates:

For NDFs on Cboe SEF as a Taker, it is mandatory for the Client to send LegSettlDate and LegMaturityDate in the NewOrderMultileg message. This information is sent to the Client as part of the SecurityStatus message in corresponding ITCH/Bookfeed sessions.

Taker

On CboeFX Taker Feeds, the Client can send Day and IOC orders. Market Day orders are supported on SPT ECN but not on NDF ECN.

TIF=DAY - Once an order is placed, if the order is not executed immediately, it stays active with OrdStatus=New and if unfilled gets cancelled only at the end of trading day.
TIF=IOC - Once an order is placed, if the order is not executed immediately, it will be automatically expired.

The ExecutionReport providrd additional information in the Text field as follows:

All IOC misses can be expired with any of these reasons:
- Lastlook decline
- Lastlook timeout
- MinQty
- LotSize
- Insufficient PB credit
- Insufficient Collat credit
- Price no longer available
Aggressive trades will contain an indication of the resting/passive-side liquidity source:
- Passive is last look
- Passive is firm

Warning

title	CBOE FX Central No Longer Supported

CBOE has shut down its “CBOE FX Central” offering. The last day of trading was 2025-11-14.

Maker

QuoteLayers

NDF: By default QuoteLayers are available for NDF and Cboe does not recommend more than 3 layers.

SPT: Only one 1 QuoteLayer is supported for SPT.

Quotes and QuoteCancels Logic

Cboe only automatically cancels the previous quote on same layer on submission of new quote. i.e. if Quote1 has 2 NoQuoteEntries and Quote2 has 3 NoQuoteEntries, then Cboe automatically replaces Quote1 with Quote2 and gateway does not sends any cancel.
MF Initiates QuoteCancel to the Venue if the latest quote has fewer rungs than previous one. i.e. If Quote1 has 3 NoQuoteEntries and Quote2 has 2 NoQuoteEntries, then on receiving Quote2, MF sends QuoteCancel of Quote1 and then send Quote2 to venue.
Client can explicitly send an empty quote, so MF will cancel the previously published quote if there is one.
If Client sends an Indicative Quote in any layer, MF replaces with 0 Price, so Cboe cancels the previous Quote on same layer.

Trade Confirmation

Client can connect to Maker feed as Firm or Lastlook Maker using configurable parameter "client_role". Please contact TOPS for the setup.

Note

title	Firm vs LastLook

Feeds configured for Maker LastLook may receive Firm ExecutionReport if the Trade is on Aggressive side.

Trade final status is only available for last look maker accounts where they are on the passive side of the trade.

Note

title	UnderlyingQty

Collapse to Mid Pegged Orders

Collapse to Mid (CTM) orders are Pegged Orders with the discretion to match at the ECN-defined mid-point price.

Clients interested in trading CTM pegged orders should ensure the following conditions are met in the NewOrderMultileg:

PegPriceType = MarketPeg (AggressivePeg)
PegOffsetType = Price
BodyPassthruKey = CollapseToMid and BodyPassthruValue = Y

Note

title	CTM Pegged Orders Matching Criteria

CTM Pegged Orders will compete to match at the ECN-defined mid-point price from the start.
CTM Pegged Orders will match opposing orders with the same entitlement.

Please refer to Order Management#PeggedOrders for more details.
