The futures market, especially the gold contract, has been a roller coaster ride lately. In just one day last Thursday, gold fluctuated by nearly $100. Let's take a look at the minimum volatility of $Gold - main 2204(GCmain)$. We can check the contract profile on the Tiger app. The contract unit is 100 troy ounces. The minimum fluctuation unit of the GC contract is 0.1 (USD/oz), equivalent to $10. In other words, when the price goes up or down, you profit or lose at least $10. Let’s take last Thursday’s trend as an example. When GC contract drops from$1976 to$1892, how much would you profit if you short gold? 1976-1892 = 84 84/0.1 * 10 = $8400 On t
