What are LME Closing Prices?
LME Closing Prices (also known as “Evening Evaluations”) are prices discovered basis LMEselect trading activity during specific “pricing periods” towards the end of the trading day. LME Closing Prices reflect the USD value of one metric tonne of the relevant metal and relevant prompt date, where the metal must comply with the requirements of the applicable LME contract specification set out in the LME Rulebook.
How are LME Closing Prices calculated?
LME Closing Prices are determined by the LME Quotations Committee based on trading activity on LMEselect including trades, bids and offers.
Depending on prompt date and other factors (like liquidity) the LME Quotations Committee calculate LME Closing Prices using a waterfall methodology and a combination of:
- volume weighted average price
- last traded price
- bids and offers
- expert judgement
