New and Modified Functionality

Existing EBS customers leveraging EBS Ai to trade EBS Market and eFix Matching Service products on CME Globex must be aware of the changes in functionality described below.

Authentication

To send logon request to EBS Ai:

  1. The EBS Ai user connects using FIX ASCII over TCP connection
  2. After establishing a network connection, user sends two logon messages:
    1. FIX session logon message (tag 35-MsgType=A) to EBS Ai
    2. Application logon request message (tag 35-MsgType=BE) with username and password to begin a new Trading Session
      1. Current usernames cannot be used, as they are not unique across Globex Firm IDs (GFIDs)
      2. New unique usernames will be issued to customers
  3. User must make configuration change to use the new username

New Username

The Legacy Ai username will not be carried forward. EBS Ai customer must register for a CME Group Login in the CME Customer Center to receive a new globally unique username and generate the API ID password. 

  • Username: The new username will be populated with the API ID.  
  • Password: To obtain an API ID password go to the CME Customer Centre login page HERE, click “Forgot password” and enter your API ID to receive an email to generate your passwords.

See the EBS Operational Readiness Guide for a new client onboarding and setup resource to assist clients with the integration of EBS Ai onto CME Globex.

Password Change

To align with CME Globex logon, EBS Ai will not support password change as part of the logon process.  If the EBS Ai client supports a periodic password change, the password must be manually changed  via the CME Customer Center. 

Self-Match Prevention (SMP)

Legacy Ai prevents users from self-matching by "matching around" orders from the same user.  EBS Ai will allows a customer to prevent the matching of orders with the same Self-Match Prevention Identifier (SMP ID), within or across GFIDs.  

Customers that need to avoid self-match must register their GFID and SMP ID via the Firm Administrator Dashboard (FADB). The SMP ID must then be associated to the GUS by CME Global Account Management.

  • GFIDs may register for as many SMP IDs as desired
  • SMP IDs may be shared across GFIDs only if the GFIDs are part of the same Institutional Group

EBS Ai customers cannot submit orders with an SMP Identifier (SMP ID). To apply SMP to EBS Ai orders, an SMP ID must be registered to the GUS in Firm Admin Dashboard. EBS Ai will then add the SMP ID to all submitted orders from that GUS before sending them to the matching engine.  The matching engine will then prevent orders from trading when the SMP IDs match.

In the event of a self-match event, the arriving order will trade around any resting order(s) with the same SMP ID.

MiFID Short Code

Legacy EBS Ai supports alphanumeric short codes. CME Globex supports only numeric short codes. Customers using alphanumeric short codes must re-register on the NEX Upload Facility (NUF) with numeric short codes.  

Market View

EBS Ai supports Price Depth market view. 

The following market view types will no longer be supported:

  • Spread view
  • Amount view
  • Full Amount view

Price Depth View

In Price Depth view, an aggregate depth book is sequenced by price, descending for bid and ascending for Offer.

EBS Ai maintains the Aggregate Depth view with the following data blocks:

  • Add - create/insert a new price (tag 279 MDUpdateAction=0)
  • Change - change quantity for a price (tag 279 MDUpdateAction=1)
  • Delete - remove a price (tag 279 MDUpdateAction=2)

An Aggregate book is built from a series of data blocks which indicate whether an entry is to be inserted (Add), changed (Change), or removed (Delete). All data blocks are issued for a specified entry type (tag 269), and price (tag 270). The incremental instruction approach assumes the use of the EBS Ai Market Data Incremental Refresh (tag 35-MsgType = X) message.

When a new price level is added to the order book, and followed by updates to delete an existing price level and add a new price level:

  • MDUpdateAction to add the entry (tag 279 = 0) will be published in one 35=X message
  • MDUpdatesAction to delete the entry (tag 279 = 2) and add the new entry (279=0) will be published in a separate 35=X message
Price Depth View Example

The example in this topic shows the update performed on an existing Price Depth book when a new price level is added to the order book, and followed by an update message to delete the existing price.

Market by Price Depth 

EBS Ai will not allow the user to specify the number of price levels. Client systems must determine the maximum number of levels for each instrument from tag 20100-PriceDepth in the logon response message. 

The Subscribe message sent by the Client will be rejected if tag 264-MarketDepth does not equal '0' or the price depth sent in logon response.

Market Data and Trading Subscription

When the  EBS Ai client sends Market Data Subscription Request for the specific instruments,

  • For a trade only subscription request, the EBS Ai’s response to each successful request is a Market Data – Snapshot/Full Refresh (W), devoid of initial bid and offer values.
  • For a request to trade and subscribe to market views, the EBS Ai’s response to each successful request is composed of two message types:
    • Market Data – Snapshot/Full Refresh (W) message, containing the full set of market data
    • Market Data – Incremental Refresh (X) messages, sent whenever there is a change to the market data

Market Data – Incremental Refresh

This table summarizes the Market Data-Incremental Refresh message differences across Legacy Ai and EBS Ai.


Legacy Ai

New EBS Ai

Market Data Subscribe Response

When a client is subscribed for multiple instruments in a single Subscription Request, Incremental Refresh messages will be sent after all Snapshot/Full Refresh messages are sent for subscribed instruments.

When a client is subscribed for multiple instruments in a single Subscription Request, EBS Ai may interleave Snapshot/Full Refresh messages with Incremental Refresh messages.

Market Data Update

The Incremental Refresh message can contain updates for multiple instruments in a single message.

Each Incremental Refresh message contains a single instrument update and not batch multiple instruments together.

MDEntries (tag 269)

MDEntries are published for Bid/Offer, EBS Best offer/EBS Best Bid, and Trade  (Paid/Given) in a single  35=X message.

MDEntries are published as follows:

  • Bid/Offer and EBS Best offer/EBS Best Bid updates in one 35=X message 

  • MDEntries for Trade (Paid/Given) in a separate 35=X message

MDLastIncrementalRefresh (tag 20203)

Send tag 20203=1 to indicate  the last Incremental Refresh message specific to the instrument(s) contained in each client subscription.

Send tag 20203= 1 to indicate  the last Incremental Refresh message for any updates that happened on the market for overall subscribed instruments (i.e. client can send multiple subscription requests for different instruments each time).

MDLastIncrementalRefresh (tag 20203)

EBS Ai will also notify the client whether or not this market data update message is the last in the corresponding time-slice by means of custom tag 20203-MDLastIncrementalRefresh.

Legacy Ai currently sends tag 20203=1 to indicate the last Incremental Refresh message specific to the instrument(s) for each Subscription Request.

EBS Ai will send tag 20203=1 to indicate the last Incremental Refresh message for any updates that happened on the market for overall subscribed scope as follows:

  • Singe subscription request with multiple instruments
  • Multiple subscription requests with one instrument each
EBS Ai clients that expect tag 20203 to be set on a per-subscription basis within a publication interval should process each 35=X incremental update message independently, trimming the associated books and performing other per-instrument processing as appropriate.

Single Subscription Request with Multiple Instruments

SingleSubscription3Instruments

3 Subscription Requests with 1 Instrument in Each

3Subscriptions

Order Price Validation

Legacy Ai provided additional, optional price validations that could be requested by the user as part of the logon process. These additional validations are deprecated.

Order Amend Request Reject

Legacy Ai cancels original order immediately when an Order Amend Request is rejected due to, for example, lack of credit.   Once the Order Amend has been rejected, no more messages pertaining to the rejected request will be sent to the client.

EBS Ai will emulate Legacy Ai behavior and cancel the order if an Order Amend Request is rejected. This emulation may have certain differences from the Legacy Ai.

CME Group strongly recommends customers relying upon Legacy Ai Order Amend functionality consider testing EBS Ai Cancel/Replace functionality prior to migration.

Application Logon

The Logon process allows the client to configure certain parameters that will be in effect for the duration of the session. The client will receive a response indicating a successful Logon, a response indicating an existing session needs to be cancelled, or a response indicating the password has expired, or a logon failure message.

The Logon Response sent by EBS Ai before the market opens on Sunday startup will reflect the Monday as Trade Date, and the Settlement Date reflect a Monday trade date.

For instance, a T+2 trade will have the following dates before the market opens on Sunday:

  • TradeDate (Tag 75): Monday
  • SettlDate (Tag 64): Wednesday

Trading Session List

The Trading Session List immediately following a successful Logon Response will be sent only to clients who requested the Fixing information in the Logon Request and are enabled for Fix orders. This message is not sent for “Standard” sessions.

TradSesOpenTime will no longer accurately depict the eFix schedules. The following placeholder times will be sent:

  • On Sundays, the tag 342-TradSesOpenTime value will be set to 17:00 GMT across all products.
  • On weekdays:
    • If the Fixing Time doesn't coincide with 17:00 ET or 18:00 ET, then the tag 342-TradSesOpenTime value will be set to 17:00 ET (expressed in "GMT").
    • If the Fixing Time coincides with 17:00 ET or 18:00 ET, then the tag 342-TradSesOpenTime value will be set to 19:00 ET (expressed in "GMT").

As of May 15, 2022, the accurate eFix schedule will be found on the CME Group Trading Hours page.

Application Logoff

Upon an Application Logoff, the EBS Ai will cancel all working orders  without sending cancel acknowledgments. 

Legacy Ai

New EBS Ai

  • Client sends the Logoff Request message
  • Legacy Ai cancels all working orders and send Execution Report with OrdStatus = Cancelled[4] to client
  • Legacy Ai sends Logoff Response message
  • Client sends the Logoff Request message
  • EBS Ai cancels all working orders without sending cancel acknowledgment to client
  • EBS Ai sends Logoff Response message

Trading Session Status

EBS Ai sends Trading Session Status (35-MsgTyp=h, 340-TradSesStatus=2 or 3) message to notify EBS Ai clients of eFix Open or Close state of the trading session.  

  • eFix Instruments are grouped together to create Trading Session ID
  • Trading Session Status messages are sent at the Trading Session ID level

In the unlikely event of a CME Group component failure or unscheduled market close of an eFix instrument, EBS Ai will send a single “Closed” Trading Session Status message for all eFix instruments within the same Trading Session ID.   As a result, the market can appear closed on EBS AI on some eFix instruments even though they are open.

For example,  If eFix USD/CAD WM 1600 London is paused, a  single “Closed” Trading Session Status message will be sent for all three eFix instruments in the trading session ID 8 even though eFix EUR/NOK WM 1600 London and eFix NZD are open.

Trade Query

EBS Ai does not support retransmission of messages. To ensure no trades are lost during session interruption, EBS Ai provides the Deal Query feature.

  • Deal Query can be used to request information about deals executed within the most recent week by OrderID or ClOrdID.
  • Queries can be performed based on ClOrdID or OrderID.
  • Deal Query allows the EBS Ai client to retrieve the status and details of deals associated with the orders on CME Globex.

  • To use Deal Query, the Ai client application must retain one of the IDs associated with the order; ClOrdID or OrderID.

  • EBS Ai supports Deal Query with the Trade Capture Report Request, Trade Capture Report Request Ack, and Trade Capture Report FIX messages.

    • The Trade Capture Report message contains information for the associated deals based on selected criteria (requested by unique customer Reference ID or Globex order ID) within a week.

    • For a specific order that resulted in multiple deals, a successful Deal Query returns a Trade Capture Report Request message containing all deal information related to that order.

    • If there is no result for a valid Deal Query, a Trade Capture Report Request Ack message returns with the total number of Trade Reports set to zero.

    • Deal Queries are limited to retrieving deals for the current week. Attempts to retrieve earlier deals will result in a Report Ack message with a Warning message indicating the deals were out of the time range.

      • EBS Ai rejects Trade Capture Report Requests submitted without qualifiers, more than one qualifier, with incorrectly formatted references, or with invalid deal or order IDs.

Counterparty Trader ID

Counterparty Trader ID will no longer be provided via EBS Ai. The tag 448-PartyID value will be set to 'GUS' for Counterparty Trader ID (tag 452-PartyRole = 37).
