What are the LME Unofficial Prices and how are they calculated?
LME Unofficial Prices are determined using a Volume Weighted Average Price (VWAP) for 3 months based on transactions from LMEselect over a specified 5-minute pricing period for each contract between 15.00-5.35. Where the minimum volume requirement threshold (MVR Threshold) is not met, the price will be determined using a waterfall methodology. All other prompt dates will be determined using available spread information.
