XAGUSD Position Size Calculator
Calculate XAG/USD lot volume from an entered account-risk budget and direction-aware entry-to-stop distance. Contract ounces, silver pip convention, broker tick, lot step, minimum, maximum and account conversion remain explicit.
Enter the risk plan and silver symbol rules
Use a declared balance, equity or strategy allocation as the risk basis. Prices are USD per troy ounce.

Stop-distance sensitivity
Five distances around the entered stop show how volume changes when every other assumption stays fixed.

How XAGUSD position size is calculated
Risk budget in USD = account risk × USD per account-currency unit
Stop distance = |entry − stop| in USD per oz
Raw ounces = USD risk budget ÷ stop distance
Raw lots = raw ounces ÷ contract ounces per lot
Placed lots = floor(raw lots to the entered minimum-and-step grid)
The engine floors volume so rounding cannot push the modeled exact-stop loss above the entered risk budget. It withholds volume instead of rounding up when the raw result is below the broker minimum, then applies the entered per-deal maximum if needed.
Worked example from the audited fixture
A USD 10,000 risk basis at 1% creates a USD 100 budget. A buy entry at 30.00 and stop at 29.65 are USD 0.35 per ounce apart. Dividing USD 100 by USD 0.35 gives 285.7143 oz; dividing by a 5,000-oz contract gives 0.057143 raw lot.
Flooring to a 0.01 step returns 0.05 lot, or 250 oz. The modeled exact-stop risk is USD 87.50, equal to 0.875% of the risk basis, leaving USD 12.50 unallocated. This is deterministic arithmetic, not a suitable-position claim.
Use and limitations
- Declare whether the risk basis is balance, equity or a smaller strategy allocation.
- Verify the contract multiplier, tick size and volume rules for the exact silver symbol and account.
- Use the planned direction, entry and stop; do not paste a pip count into a price field.
- The account conversion is manually entered and not timestamped.
- Margin, leverage, liquidation, portfolio heat and correlated exposure require separate checks.
- The result is not an order, loss guarantee, safe-lot label, recommendation or financial advice.
Frequently asked questions
- Convert the entered account-risk budget into USD, divide by the entry-to-stop USD-per-ounce distance, then divide the resulting ounces by contract ounces per lot.
- It floors raw volume to the entered broker minimum-and-step grid so volume rounding alone cannot make the modeled exact-stop loss exceed the risk budget.
- The page withholds placed volume. It does not round up to the broker minimum because that could exceed the entered risk budget.
- No. Enter the planned entry and stop as USD-per-ounce prices. The page derives distance in USD, the selected silver pip convention and broker ticks.
- Yes. A buy requires a stop below entry and a sell requires a stop above entry. After that direction check, sizing uses the absolute price distance.
- Not in this exact price-distance calculation. Leverage changes margin and liquidation conditions, which must be checked separately with broker-specific rules.
- No. The stop is assumed to execute exactly at the entered price. Realized loss can be larger after spread, slippage, gaps, fees or partial execution.
- No. It is the volume that fits entered arithmetic and broker constraints. The page does not assess suitability, stop quality, market conditions or total portfolio risk.
Sources and methodology
- MQL5 Reference — OrderCalcProfit — official pre-evaluation interface using order type, symbol, volume, open price and close price.
- MQL5 Reference — Symbol Properties — defines contract size, tick size, minimum volume, maximum volume and volume step as separate properties.
Version 2.0.0 performs deterministic entered-data arithmetic locally. It does not call a trading server or claim its 5,000-oz example matches a broker symbol.
