The Ring

LME Ring

Our open-outcry trading floor, the Ring, is central to the process of price discovery.

The LME Official Prices are discovered on the trading floor.

Only Category 1 Members can trade in the Ring. 

Ring sessions & trading times

Each LME metal is traded in highly liquid five-minute Ring sessions which are themselves representative of global supply and demand.

Trading on the Ring begins at 11.40 and closes at 17.00. 

Futures prices from the Ring

Market users can access a wide range of price data directly from the LME's open outcry trading floor via our network of licensed data distributors.

Data includes:

  • Separate bid, ask and trade prices for all futures contracts quoted outright, spread or average
  • Highest bid and lowest offer prices for futures 3 month prompt dates following each ring and kerb trading session
  • Daily official cash, 3 month, 15 month, 27 month, DEC1, DEC2, DEC3 prompt date prices (where applicable) for metal futures contracts following the second morning Ring trading session
  • Daily official FX rates following the second morning Ring trading session
  • Daily moving monthly average FX rates

Open outcry and unique prompts

Open-outcry trading is important for the LME because of its unique prompt-date structure. There are up to 200 tradable dates per LME metal and open outcry is an efficient way of trading multiple dates.

Ring trading runs concurrently with the LME's other platforms, LMEselect and the inter-office telephone market.
