Comparative metrics
Usually the relative values between compared commodities are discussed in the market with market participants. The negotiation includes , comparison to the same commodity or comparison to a more traded but slightly different specification commodity in the same market centre, or comparison to the same commodity traded for a different delivery timing or comparison to the commodity’s primary feedstock or primary derived products.
Lastly comparison to trade in the same commodity but in a different modality for example a vessel or in a different total volume as in full cargo load versus partial cargo load.
