La stratégie d'inversion de tendance de modèle dynamique utilise la régression linéaire pour prédire les prix et les lignes moyennes mobiles pour former un modèle pour générer des signaux de trading.
La combinaison des signaux ci-dessus avec des confirmations multiples évite de fausses fuites et améliore la précision.
La stratégie d'inversion de tendance de modèle dynamique intègre la prédiction de régression linéaire et les modèles de moyenne mobile pour capturer les inversions de tendance.
