Record each purchase once — what you bought, how much of it, what you paid and what spot was that day — and everything else follows: your true cost per ounce, the premium you paid over spot, what the stack is worth now, and how it is split between metals by value and by weight. Enter quantities in grams or troy ounces; both are shown either way.

Current / oz and sale spread are the only figures you type here — a positive spread is the premium a buyer pays you, a negative one is a dealer's buyback discount. Everything else comes from the purchase ledger.
