Scheduled CME UAT maintenance window - every Wednesday 5am-12noon CST. Please refrain from testing during this time as environment may be unstable. 

• The product thresholds and limits published in SecurityStatus message are specified in base currency.
• Liquidity for FXSpot+ orders can be from other FXSpot+ orders, or from FXLink spread orders. It is therefore possible for MDEntrySize to be a non-rounded amount indicating implied liquidity.
• MaxShow not supported for FXSpot+
• If an order is partially filled, and the remaining quantity falls below the Minimum Order cancel threshold for the product, the remaining order will be canceled by CME.

In-flight mitigation (IFM) is an optional feature on CME Globex that allows client systems submitting cancel/replace messages to prevent overfilling in the event that the original order is filled while the cancel/replace message is "in-flight" during processing.

https://www.cmegroup.com/confluence/display/EPICSANDBOX/iLink+Order+Cancel-Replace+and+In-Flight+Mitigation

This feature is currently disabled by default via Whisperer. If clients wish to utilise this feature, they should ensure that their MultilegOrderCancelReplaceRequest message includes:

• BodyPassthruKey   = "OFMOverride"


• BodyPassthruValue = "Y"

Refer to Passthru Fields below for details.

Please note that On-SEF NDF Tailored Order Book feature is not supported by the MarketFactory API.

Clients are advised to contact the MarketFactory Delivery Team incase they would like to participate in trading the Tailored Order Book. 

CPI will allow the submission of orders with sub-pip prices when trading the eligible Spot instruments.

Clients can place orders with sub-pip price in Price/ tag44 in NewOrderMultileg. For Price Discretion orders to match CPI orders, clients should populate the Alternate Globex Minimum Tick values [available as AltMinPriceIncrement BodyPassthruValue on the ebs_market_mdp3_sbe_udp and ebs_market_mdp3_sbe gateways] on the DiscretionOffsetValue field in NewOrderMultileg.

Supported instruments, minimum tick, and minimum quote life as per the Conditional Price Increment CME confluence page.

 iLink3 can report multiple trades in a single Execution Report message as explained in the links below;

https://www.cmegroup.com/confluence/display/EPICSANDBOX/iLink+3+Binary+Order+Entry+-+EBS+Market+on+CME+Globex#iLink3BinaryOrderEntryEBSMarketonCMEGlobex-FillorKill(FOK) and

https://www.cmegroup.com/confluence/display/EPICSANDBOX/iLink+3+CPT+Reconciliation

In such cases, Enterprise gateway generates multiple ExecutionReports, with OrderEventExecID from the individual match event  appended to the ExecID in the format described below.

	ExecID = ExecID:OrderEventExecID

Clients can use the second part of ExecID, after ":", to reconcile with the CPT Dropcopy reports. 

Please note: Client order with TimeInForce=FOK will either be filled in full or eliminated at all times. It is possible that such orders, can have more than one matching event, resulting in more than one ExecutionReports to clients.

Effective Sunday, August 13 (trade date Monday, August 14), CME Group will implement enhancements to iLink 3 EBS Fill and Kill (FAK) and Fill or Kill (FOK) order behavior where credit is insufficient. With this change, if an FAK/FOK order cannot match due to insufficient bilateral credit, it will be accepted and then cancelled.

If an FAK/FOK order cannot match due to insufficient bilateral credit, Whisperer clients will receive ExecutionReport with OrdStatus = New and subsequently ExecutionReport with OrdStatus = Cancelled.

Currently, if an FAK/FOK order cannot match due to insufficient bilateral credit, the order is accepted and eliminated.

Background of EBS Market NDF Trading

• EBS Market (CLOB) operates Spot FX and precious metals markets under the legal entity EBS SERVICE COMPANY LIMITED (MIC: EBSC)
• NDFs operated under the same legal entity venue as Spot and Precious Metals until 2013. 
• In 2013, a Swap Execution Facility (SEF) called NEX SEF (MIC: NEXS) was launched to address regulatory requirements in the US. 
• US-located clients began trading “on-SEF”, while EMEA and APAC continued trading “off-SEF” on the legacy venue. 
• In 2017, the off-SEF instruments were migrated to a separate regulated venue, a Multilateral Trading Facility (MTF) called BEL MTF (MIC: XEBS). 
• Late last year, the CFTC reaffirmed the no-action relief previously given to MTF venues, allowing full access from US participants (previously restricted to accessing only SEF venues.) 
• This cleared the way for CME to merge all NDF trading onto the MTF, thus removing bifurcation from the NDF market. 

Single Liquidity Pool (SLP) Timeline: Beginning 30 September 2024, EBS Market NDFs will no longer trade on the NEX SEF and the BEL MTF; all NDF trading will happen on the BEL MTF. 

• No changes will occur to existing MTF trading, connectivity or venue setup. 
• SEF trading will no longer be allowed (order entry disabled)
• SEF will remain live for contingency purposes
