How this service works
Signierte Slippage-Kosten. Positiv bedeutet nachteilige Ausführung, negativ vorteilhafte Ausführung; Richtung ist vom Aufrufer. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
A signed numeric slippage cost in account currency. A positive value indicates the execution was adverse (worse than requested), a negative value indicates a favorable execution. All arithmetic is performed using the caller-supplied prices, quantity, direction, and FX conversion rate — no market data or brokerage access is involved.
Example use cases
Post-trade execution quality audit
“I just filled a sell order of 10,000 units — requested price was 98.50 but we got filled at 98.40. Direction is -1 and the quote-to-account rate is 1.0. What's the signed slippage cost?”
Algo trading performance monitoring
“Our algo bought 250 units with a target price of 45.200 and got executed at 45.215. Direction is +1, quote-to-account rate is 0.92. Compute the signed slippage so I can log it in our performance dashboard.”
FX trade slippage in reporting currency
“We placed a forex buy (direction +1) for 1,000,000 units at a requested rate of 1.0823 but the broker filled us at 1.0831. The quote-to-account conversion is 0.9950. Calculate the signed slippage cost in account currency.”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/slippage?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, auditable computation of signed slippage cost from caller-supplied trade data — especially in post-trade reporting, execution quality analytics, or algorithmic trading pipelines. It is not a data feed and does not fetch live prices; prefer it when you already have both the requested and executed prices and need the signed cost figure in account currency.
Side effects
- Missing required fields (quantity, direction, executed_price, requested_price, quote_to_account) returns a validation error
- Values outside allowed range (e.g. price or quantity exceeding 1e12 or below 1e-12) are rejected
- Direction not in enum [-1, 1] causes a schema validation failure
- Payment not provided or insufficient USDC triggers an HTTP 402 response
