La Stratégie de négociation d'inversion de rupture de volatilité est une stratégie de négociation d'inversion qui suit les canaux de prix avec des points de stop profit et de stop loss mobiles adaptatifs.
La stratégie utilise d'abord l'indicateur Average True Range (ATR) de Wilder pour mesurer la volatilité des prix. Elle calcule ensuite la Average Range Constant (ARC) en fonction des valeurs ATR. L'ARC représente la moitié de la largeur du canal de prix. Ensuite, les bandes supérieures et inférieures du canal sont calculées comme les points de stop profit et stop loss, également appelés points SAR. Lorsque les prix dépassent la bande supérieure, une position courte est ouverte. Lorsque les prix dépassent la bande inférieure, une position longue est ouverte.
En particulier, l'ATR sur les dernières N barres est d'abord calculé. L'ATR est ensuite multiplié par un facteur pour obtenir l'ARC, qui contrôle la largeur du canal de prix. Ajouter l'ARC au prix de clôture le plus élevé sur N barres donne la bande supérieure du canal, ou le SAR élevé. Soustraire l'ARC du prix de clôture le plus bas donne la bande inférieure, ou le SAR bas. Si les prix se ferment au-dessus de la bande supérieure, une position courte est prise. Si les prix se ferment en dessous de la bande inférieure, une position longue est prise.
Les solutions:
La stratégie de trading de renversement de rupture de volatilité utilise des canaux pour suivre les changements de prix et inverser les positions lorsque la volatilité augmente. Elle fonctionne bien sur les marchés à plage avec des renversements, générant de bons rendements si les points de renversement sont identifiés avec précision.
