Understand the product construction
A commodity price shown on a screen may refer to a spot reference, a futures contract or a provider's continuous derivative. Those structures can produce different holding adjustments. A change between futures references, for example, is not automatically the same thing as interest on borrowed funds. Start with the contract description and identify whether an entry represents financing, rollover, a price adjustment or another separately defined charge.
Check each calculation input
For an actual adjustment, retain the position size, direction, contract multiplier, relevant reference prices, dates and currency. Apply the published method step by step and compare the result with the statement, including rounding and conversion. FYLU has not supplied a commodity financing or rollover methodology. Do not use a worked educational example as an estimate of a live charge without the applicable specifications and effective fee schedule.
