PER-OUNCE QUOTE / CONTRACT DOLLARS

Gold Option Premium and Contract Cost

Convert displayed premium into auditable cash flow using multiplier, contracts, trade side, spread and fees.

QUOTE UNIT → CASH AMOUNT

A per-ounce premium becomes a contract cost only after applying the multiplier

A displayed premium of $40 is not necessarily forty dollars of cash. For a 100-ounce GC option it represents $4,000 per contract; for a 10-ounce MGC option it represents $400. Contract count, bid or ask side, commissions, exchange fees and closing or exercise costs determine the economic amount.

CASH-FLOW FORMULAS

Keep quoted premium, total debit and margin in separate columns

PREMIUM AMOUNTpremium per ounce x ounces per contract x contracts

Positive or negative cash direction depends on whether the option is sold or bought.

MULTI-LEG NET PREMIUMsum of short-leg credits - sum of long-leg debits

Report as a net credit or net debit before transaction costs.

ALL-IN OPENING CASH FLOWnet premium cash flow - commissions - exchange and routing fees

This still is not the maximum loss for short-option structures.

GC VERSUS MGC

The quote can match while total dollars differ by ten times

$40/oz premium$4,000$400
$5/contract one-side commission$0.05 per ounce$0.50 per ounce
Ten contracts1,000 oz exposure100 oz exposure

Smaller contracts improve granularity, but fixed per-contract charges become larger per ounce. Compare the intended total ounces and executable spread, not the contract label alone.

EXECUTION RECONCILIATION

Last price and midpoint are not guaranteed fills

  • Record bid, ask, last price, timestamp and displayed size for each exact option.
  • Use the ask for a conservative purchase estimate and bid for a sale estimate.
  • For a package order, compare the quoted net debit or credit with legging each side.
  • Include both opening and intended closing cost, or assignment and futures costs.
  • Do not call a net credit “income” before obligations, margin and exit costs end.

FREQUENTLY ASKED QUESTIONS

Gold option premium questions

How is a gold option premium quoted?

Gold option pages commonly display U.S. dollars and cents per troy ounce. Multiply by the contract ounces and number of contracts to obtain the premium amount, then verify current contract specifications.

Is premium the same as margin?

No. Premium is the option price. Margin is a performance-bond or risk requirement that can apply to writers and resulting futures positions.

Should I use the last trade as my cost?

Not automatically. The last trade can be stale or at another point in the spread. A buyer should inspect the current ask and a seller the current bid, timestamp and available size.
