Start with the contract, not a pip label
For a linear gold position quoted in USD per troy ounce, the cash response to a price move depends on ounces held. Convert lots to ounces using the exact contract size for the broker's symbol. The 100-ounce contract used here is an example, not a specification shared by every gold product.
Ounces = lots × troy ounces per lot
Long gross P/L in USD = (exit − entry) × ounces
Short gross P/L in USD = (entry − exit) × ounces
Different platforms may use different gold pip or point labels. Actual prices and stated ounces avoid that ambiguity. This model is not a specification for futures, options, exchange-traded funds or physical gold ownership.
The same price move has opposite effects
Assume 0.10 lot and 100 troy ounces per lot: the exposure is 10 ounces. A hypothetical long from USD 2,400 to USD 2,410 gains USD 10 per ounce, giving USD 100 gross profit. A short over the same entry and exit prices loses USD 100 gross.
Reverse the exit to USD 2,390 and the long loses USD 100 while the short gains USD 100, before costs. The absolute price movement is the same; trade direction determines the sign.
At 0.01 lot under the same contract assumption, exposure is one ounce and a USD 10 move produces a USD 10 gross change. Read what 0.01 lot of gold means before transferring these examples to another contract.
Deduct costs once, then convert consistently
Assume total extra costs of USD 3 for the winning 0.10-lot long. USD 100 − USD 3 = USD 97 net. The losing short becomes −USD 100 − USD 3 = −USD 103. Costs reduce gains and increase losses.
If entry and exit are executable ask/bid prices, spread is already inside that price difference. Include applicable commissions, financing and conversion charges without adding the same spread again. Broker minimum charges or variable rates may make a flat cost assumption unsuitable.
For a GBP account and an illustrative 1 GBP = USD 1.25, USD 97 ÷ 1.25 = GBP 77.60. The negative USD 103 result becomes −GBP 82.40. Use the conversion direction shown; multiplying by USD per GBP would be incorrect. Actual conversion arrangements may differ.
Profit scenarios and risk budgets
The distance to a target describes a potential outcome if that price is reached and executed under the assumptions. It does not estimate the probability of that happening. Raising a target can increase a displayed reward without improving the trade's prospects.
For an entry-to-stop scenario, use the gold position-size calculator, which accepts contract ounces, currency conversion and a cost reserve. The risk/reward tool compares cash-loss and cash-gain assumptions and shows how costs change the break-even win rate.
Gold can gap, spreads can widen and ordinary stops can fill beyond their trigger. Check dealing hours, margin and symbol limits with the actual provider. The calculations are educational scenarios, not evidence of a trading edge or a guaranteed maximum loss.
