Lowest favorable bid (LFB)
The Lowest Favourable Bid, or LFB, is the lowest of the inferred cash and 3-month future price for the base metals at the LME, using Metal Radar’s inferred pricing mechanism for contango/backwardation calculation.
The LFB has the following format: LME-{GOOD}.FLOW.InferredBid.
For copper that would be LME-CU:FLOW.InferredBid.
