Calculate a risk-based gold trading position size from account balance, desired risk percentage and stop-loss distance. The result translates account risk into gold units and estimated notional exposure.
Risk first, position size second.
A wider stop means more dollar risk per unit. To keep total trade risk constant, the position size must therefore become smaller. A tighter stop allows a larger theoretical position under the same risk budget.
For futures, multiply the entry-to-stop price distance by contract size to calculate dollar risk per contract. The number of contracts is then your risk budget divided by risk per contract.
Maximum risk divided by dollar risk per unit.
