How this service works
Lotgröße und Verlustbetrag. Lot = Kontostand × Risikoprozent / 100 / (Stop-Abstand × Kontraktgröße × Umrechnung). Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
Returns the computed lot size (number of lots to trade) and the corresponding monetary loss amount in account currency if the stop loss is triggered, derived purely from the supplied figures with no broker access or live market data.
Example use cases
Forex trade position sizing
“I have $5,000 in my account and want to risk 2% on a EUR/USD trade. My stop is 15 pips away, the contract size is 100,000, and the EUR/USD conversion to my USD account is 1.0. How many lots should I trade?”
Commodity risk calculation
“My trading account is $25,000. I'm trading gold and want to risk 0.5%. The stop distance is 8 points, the contract size is 100 oz, and gold is priced at 2,350 per ounce with a 1.0 account conversion. What lot size does that give me and how much am I risking in dollar terms?”
Multi-currency account sizing
“I have a 15,000 EUR account and want to risk 1.5% on a USD/JPY trade. Stop distance is 30 pips, contract size is 100,000, and the JPY-to-EUR conversion factor is 0.0062. Please calculate the correct lot size.”

Endpoint
POSThttps://handel.halowerk.com/v1/rechner/lot-size?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, formula-based lot size calculation that incorporates a currency conversion factor and you want a deterministic computation rather than a spreadsheet or manual formula. It is ideal for multi-currency accounts or cross-currency instrument trading where the quote currency differs from the account currency. It does not provide market data, broker connectivity, or investment advice — use it purely as a calculation layer in a larger trading workflow.
Side effects
- Missing required fields (equity, risk_pct, contract_size, stop_distance, quote_to_account) returns a validation error
- Zero or negative stop_distance or contract_size causes division-by-zero or validation rejection
- risk_pct above 100 or below 0 rejected by schema
- Extremely small values near minimum thresholds may produce very large lot sizes — caller must sanity-check output
- Payment not included or insufficient USDC balance returns HTTP 402
