How this service works
Signal-Fingerabdruck und Dublettenabgleich. Versionierter SHA-256 über fest kanonisiertes Signal; nur Abgleich mit gelieferter Liste, keine eigene Signalspeicherung. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
Returns a versioned SHA-256 fingerprint of the canonicalized signal, and indicates whether that fingerprint matches any entry in the caller-supplied known_fingerprints list. No signal data is stored server-side; the service is purely a computation tool.
Example use cases
Deduplicating signals in automated pipeline
“I'm receiving trade signals from multiple sources and need to know if this short signal on EURUSD with entry 1.0850, stop 1.0920, and target 1.0750 has already been seen — here's the list of fingerprints I've processed so far.”
Canonical hash for signal audit trail
“Generate a canonical SHA-256 fingerprint for a long signal on BTC with entry 68000, stop 65000, and targets 72000 and 75000 — I need to store the hash for audit purposes.”
Cross-source duplicate detection
“I'm getting signals from three different providers and want to make sure I'm not acting on the same signal twice — can you fingerprint this short TSLA signal with entry 245.00, stop 260.00, and target 220.00, and check it against these 50 known hashes I've collected today?”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/signal-fingerprint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, reproducible fingerprint of a trading signal for deduplication or audit purposes, and you already hold all price data and signal parameters yourself. This is not a broker, not a data feed, and not a signal recommender — it is purely a hashing and comparison compute tool. Prefer it over custom hashing when you need a canonicalized, versioned SHA-256 that is consistent across systems, or when building deduplication logic into a multi-source signal aggregation pipeline.
Side effects
- Invalid or out-of-range entry/stop/target prices return validation errors
- Symbol too short or too long (outside 2-24 chars) causes schema rejection
- known_fingerprints entries that are not exactly 64 characters are rejected
- Direction values other than 1 or -1 fail validation
- More than 1000 known fingerprints in the list triggers a limit error
- Missing required fields (symbol, direction, entry, stop, targets) cause 400-level errors
