Neues Modul: Visuelle Chartmuster-Erkennung (core/patterns.py) — reine Anzeige
Erkennt aus M30-Swing-Pivots: Doppeltop/-boden, Kopf-Schulter/inverse SKS, Tasse+Henkel/invers, auf-/absteigendes+symmetrisches Dreieck. Je Muster Richtung, Trigger/Nackenlinie, Measured-Move-Ziel, Status (bildet sich/bestätigt/ungültig), Güte. Dashboard-Karte #card-patterns + Disclaimer (v=116). KEIN Signal, kein Verdict-Gewicht — Signal-Einfluss erst nach Backtest (Muster-Klasse 2x verworfen, hohe Beweislast). Live getestet: findet bestätigten Doppeltop.

core/patterns.py — Visuelle Chartmuster-Erkennung (ANZEIGE, kein Signal)
|
||||
========================================================================
|
||||
Erkennt mechanisch definierte Chartmuster aus den M30-Swing-Pivots und liefert
|
||||
sie fürs Dashboard: Typ, Richtung, Nackenlinie/Trigger, Measured-Move-Ziel,
|
||||
Status (bildet sich / bestätigt / ungültig) und eine Qualitäts-Note.
|
||||
|
||||
Erkannte Muster (v1):
|
||||
• Doppeltop / Doppelboden (2 gleiche Extrema + Nackenlinie)
|
||||
• Kopf-Schulter / invers (SKS) (3 Extrema, Mitte am höchsten/tiefsten)
|
||||
• Tasse+Henkel / invers (heuristisch: abgerundetes Extrem + Henkel)
|
||||
|
||||
⚠ REINE ANZEIGE — KEIN Trade-Trigger, KEIN Verdict-Gewicht. Signal-Einfluss ERST
|
||||
nach Backtest (`backtest_patterns.py`, noch zu bauen): dieselbe Klasse (Doppeltop,
|
||||
Struktur) ist im Projekt schon 2× als SIGNAL verworfen (`backtest_doubletop.py`,
|
||||
`backtest_structure.py`) → hohe Beweislast. Das Modul zeigt nur den Ist-Zustand +
|
||||
das (mechanische) Measured-Move-Ziel, damit man sieht, was ein Kommentator meint.
|
||||
|
||||
Thread-sicher wie structure.py: refresh_market(sym) holt M30-Bars unter mt5_lock
|
||||
(~30 s gedrosselt), snapshot() liefert den letzten Stand ohne MT5-Call.
