"One Lot" Is a Standardized Trading Quantity
Many beginners, upon first seeing gold futures quotes, mistakenly think "one lot" refers to a small amount of gold, perhaps equating it to buying one gram or ten grams. In reality, in gold futures, "one lot" isn't an arbitrary quantity but a standardized contract unit set by the exchange.
Taking the Shanghai Futures Exchange (SHFE) gold futures as an example, the trading unit is 1,000 grams/lot, meaning one lot of gold futures corresponds to 1,000 grams of gold—or 1 kilogram. The trading code is AU, with quotes in RMB per gram. Thus, the price shown on the board is per gram of gold, not the total value of one lot.
When Viewing Quotes, Connect "RMB/Gram" with "One Lot"
Understanding gold futures contracts hinges on combining the quote unit with the contract unit. If the gold futures price shows a certain value per gram, it represents the price per single gram; but one lot corresponds to 1,000 grams, so the contract scale is that per-gram price multiplied by 1,000 grams.
This is why gold futures prices might fluctuate by just a few jiao (cents) per gram—when scaled to one lot, the changes amplify into more noticeable amounts. SHFE gold futures' minimum price tick is 0.02 RMB/gram, seemingly just two fen (cents), but for one lot of 1,000 grams, the minimum change equates to a 20 RMB contract value shift.
One Lot Isn't a Single Gold Bar, But It's Tied to Physical Standards
One lot of gold futures represents 1,000 grams of gold but doesn't mean you'll receive a 1 kg gold bar with every trade. Gold futures are standardized contracts where the exchange unifies specifications like trading variety, unit, quote method, contract months, and delivery rules, around which participants buy and sell.
In physical delivery, SHFE gold futures' delivery unit is 3,000 grams, which doesn't contradict the "1,000 grams/lot" trading unit. Simply put: daily trading uses 1,000 grams per lot; physical delivery follows the exchange's specified unit and grade rules. Approved delivery grades include domestic gold ingots with purity ≥99.95% and other exchange-recognized standard ingots.
Why Beginners Must First Grasp the Contract Unit
Beginners viewing gold futures shouldn't just watch price ups and downs—they must first know they're seeing "per-gram prices" for standard "1,000-gram/lot" contracts. Focusing only on the board's unit price can lead to underestimating how price changes impact account results.
The contract unit acts like a ruler, determining the monetary impact of every price tick. Once understood, viewing gold futures quotes, volumes, contract months, and fluctuations becomes clearer. Gold futures aren't simply "buying gold" but trading standardized gold contracts under exchange rules. Grasping how much one lot represents is the first step in understanding gold futures.
