An explicit-unit gold example
For an illustrative $10,000 balance and chosen 1% risk, the budget is $100. An entry at $2,500 and a stop at $2,495 create a $5 price distance. If the product has 100 troy ounces per lot, price risk is $500 per lot. Before costs, $100 ÷ $500 = 0.20 lots, or 20 ounces. A different contract size changes the result.
Costs, increments and short positions
Enter any estimated round-trip costs per lot and a percentage fee only if that matches your provider’s charging method. For a short position, the stop must be above entry. The calculator rounds down; it does not move your invalidation level to force a larger order.
Review the invalidation guide before sizing. Stop slippage, market gaps and unexpected costs can make realized losses larger than the planning estimate.
