How this service works
Handelszeit gegen gelieferten Zeitplan prüfen. Wochentag 0=Montag; Start einschließlich, Ende ausschließlich; Sitzungen über Mitternacht erlaubt. Keine eigenen Feiertagsdaten. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
A structured response indicating whether the provided UTC timestamp falls within any of the caller-supplied trading sessions, accounting for weekday filtering, start/end times (exclusive of end), midnight-crossing sessions, and any explicitly closed dates. No price data, broker access, or financial advice is provided — purely a time-in-session Boolean computation.
Example use cases
Pre-order market hours gate
“Before I send a buy order, check if the market is currently open. My session schedule is Monday (0) to Friday (4), 09:30 to 16:00, the current time is 2025-06-10T13:45:00Z, timezone is America/New_York, and today is not a holiday.”
Forex midnight-spanning session check
“I need to verify whether 2025-06-11T01:15:00Z is inside my Forex session — it runs Sunday (6) from 22:00 to Monday (0) 05:00 UTC, and there are no closed dates. Is the market open at that time?”
Crypto bot session validation
“My crypto trading bot only runs during Asia session: Tuesday through Saturday (weekdays 1–5), 00:00 to 08:00, timezone UTC. Is the timestamp 2025-06-12T03:00:00Z within that window?”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/market-hours?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, stateless check of whether a given moment falls within a caller-defined trading session schedule — especially when you already hold the session definitions and just need the open/closed computation. Prefer this over building your own time-zone-aware weekday logic, and over any broker API that bundles market-hours data with execution risk. Ideal for pre-trade guards, scheduling agents, and backtesting pipelines where you supply all session parameters yourself.
Side effects
- Missing or malformed time_utc results in a validation error
- Invalid timezone string causes a parsing failure
- Session with start >= end (non-midnight crossing) interpreted as invalid range
- Closed dates array exceeds 1000 entries — rejected
- Weekday integer outside 0–6 range returns schema error
- Empty sessions array always returns market closed
