    o Counterparty ‘AUC’

  • 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)

  • Carry trades that straddle multiple Time to maturity buckets will be categorised by the maturity bucket with the lowest LIS threshold.
  • Options and TAPOs are currently not considered for PTT
  • If members wish to test on LMEsmart but do not want to initiate an auction, trades entered with the below will not initiate an auction:
    o Trades with higher lots than the LIS levels detailed above
    o Trade with categories other than “Normal” or “Giveup Executor/Clearer”
    o Trades with Commodity Derivatives Indicator set to “Yes” (only one side of the trade needs to contain this for the whole trade to not be considered for PTT)

LMEselect, LMEselectMD and LMEsource applications in MTB environment will not be available for Members and other market participants to perform their own system/software testing from 03 August 2020 until further notice.
