How this service works
Margin-Referenz für lineare Kontrakte. Notional / Hebel; keine Broker-Marginstaffeln. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
Returns the computed margin requirement for the linear contract position, expressed as notional value divided by leverage, optionally converted to account currency via the caller-supplied quote_to_account rate. No live market data is fetched; all figures are purely derived from caller-supplied inputs.
Example use cases
Crypto futures margin pre-trade check
“Before I place a trade, can you figure out how much margin I need? It's a linear BTC futures contract — 0.5 lots, current price 67000, contract size 1, leverage 10x, and my account is already in USD so the quote-to-account rate is 1.”
Forex CFD position sizing
“I'm looking at a EUR/USD linear CFD: 3 lots, price 1.085, contract size 100000, leverage 30, and the quote-to-account conversion is 1 since my account is in USD. What margin do I need to put up?”
Multi-leverage margin comparison
“Can you calculate the margin required for a linear contract at price 5000 with 1 lot and contract size 10, first at 5x leverage and then at 25x leverage — quote-to-account rate is 0.92?”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/margin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pure arithmetic margin calculation for linear contracts (notional/leverage) without any broker integration, live pricing, or account-specific margin tier logic. Ideal for pre-trade sizing checks, backtesting pipelines, or agent workflows that already have all market data and want a stateless, deterministic margin figure. Not suitable when broker-specific margin schedules, tiered margin, or live price feeds are required.
Side effects
- Missing required parameters (lots, price, leverage, contract_size) returns validation error
- Values outside allowed range (e.g. leverage below 1e-12 or above 1e12) rejected
- quote_to_account not provided may cause result in quote currency only
- Zero or negative effective leverage causes division error
- Non-numeric input values rejected with schema validation error
