Useful testing information for pre-trade transparency (PTT) Member Testing – MTA

Please note: from Monday 19th October the auction duration has been reduced from 30 minutes to 5 minutes in MTA

Trades that fit the PTT criteria (liquid product, below the LIS threshold that does not qualify for any other approved waiver or exemption) will be held in the Auction state for 5mins in the member test environment as opposed to 30 seconds when the service goes live in November as a production offering. This will allow members adequate time to test the different scenarios for initiating trades as well as participating bids and offers.

To initiate an auction, trades must contain:

  • Venue – Inter-office
  •  Category – Normal or Giveup Executor/Clearer
  •  Price Type – Current
  •  Product listed on the LIS table
  •  Volume under the LIS threshold
  •  Both sides of the trade must have Commodity Derivatives Indicator set to “No

The Post Trade Operations team will be loading trade files between 12pm and 2pm on Tuesdays, Thursdays and Friday for the initial two weeks of Member Test from the 14th September.
These trade files will create auctions for members to participate in. Price, prompt, quantity and auction details will be published onto the LMEsmart Test page so members can enter participating bids and offers.

  • Auction period: 5 minutes
  • Participating bids and offers should contain the below:
    o Venue – Inter-office
    o Category – Normal
    o Price Type – Current
    o Relevant prompt/s for the auction
    o Relevant price/s for the auction
    o Auction ID (enter into the Public Reference field)
    o Relevant Trade time
    o Counterparty ‘AUC’
    o Active auction details will be published on the LMEsmart Member Test web page every half hour between 12pm and 2pm Tuesday, Thursday and Fridays.
  • If one side of the below trade types are cancelled, both sides will be cancelled to prevent matching with auction participants:
    o Client crosses
    o Give ups (member to member and client crosses)
  •  Members can also use their member test counterparties to test auction initiations and auction participation
  •  LIS levels: (TTM_0_1Y = TOM to 1 Year forward, TTM_1_2Y = 1 Year forward to 2 Years forward, etc

    o Trades with higher lots than the LIS levels detailed above
    o Trade with categories other than “Normal” or “Giveup Executor/Clearer”
