GO-Strategie

Diese Strategie berechnet einen zusammengesetzten GO-Wert auf Basis exponentieller gleitender Durchschnitte (EMA) der Eröffnungs-, Hoch-, Tief- und Schlusskurse multipliziert mit dem Volumen. Handelsentscheidungen werden anhand des Vorzeichens und des Niveaus des GO-Wertes getroffen.

Formel

GO = ((C - O) + (H - O) + (L - O) + (C - L) + (C - H)) * V

Dabei gilt:

  • C, O, H, L – EMA-Werte der Schluss-, Eröffnungs-, Hoch- und Tief-Kurse.
  • V – Volumen der verarbeiteten Kerze.

Handelsregeln

  • Long eröffnen: GO > OpenLevel
  • Short eröffnen: GO < -OpenLevel
  • Long schließen: GO < (OpenLevel - CloseLevelDiff)
  • Short schließen: GO > -(OpenLevel - CloseLevelDiff)

Parameter

Name Beschreibung
MaPeriod EMA-Periode für die Preisglättung.
OpenLevel GO-Niveau zum Auslösen neuer Positionen.
CloseLevelDiff Differenz zwischen Eröffnungs- und Schließniveau.
ShowGo Ob GO-Werte protokolliert werden.
CandleType Art der für die Verarbeitung verwendeten Kerzen.

Die Strategie arbeitet auf abgeschlossenen Kerzen und verwendet Marktorders für das Positionsmanagement.
