Exp TSI CCI-Strategie

Diese Strategie berechnet den True Strength Index (TSI) auf Basis des Commodity Channel Index (CCI) und handelt auf Kreuzungen mit einer Signallinie.

Logik

  • CCI mit dem angegebenen Zeitraum berechnen.
  • CCI-Werte mit kurzen und langen Glättungslängen in den True Strength Index einleiten.
  • Den resultierenden TSI mit einem EMA glätten, um eine Signallinie zu erhalten.
  • Long gehen, wenn TSI über die Signallinie kreuzt.
  • Short gehen, wenn TSI unter die Signallinie kreuzt.

Parameter

  • Candle Type – Zeitrahmen der für die Analyse verwendeten Kerzen.
  • CCI Period – Zeitraum für den Commodity Channel Index.
  • TSI Short Length – kurze Glättungslänge des TSI.
  • TSI Long Length – lange Glättungslänge des TSI.
  • Signal Length – EMA-Länge für die TSI-Signallinie.

Indikatoren

  • Commodity Channel Index
  • True Strength Index
  • Exponential Moving Average
