Stratégie renforcée des filets de pêche
Cette stratégie améliore la stratégie classique du filet de pêche en ajoutant des seuils de signaux d'achat/vente et un stop loss pour former un système de suivi de tendance plus complet.
La stratégie du filet de poisson évalue les tendances du marché en calculant la force centroid des prix, qui reflète la relation entre le prix et le volume.
La clé du calcul de la force centroid réside dans la relation entre le prix et le temps. En termes simples, les changements de prix récents ont plus de poids pour influencer le jugement général de la tendance, tandis que les prix plus anciens ont des poids plus petits.
Mais l'original Fish Net ne jugeait que le long/court en fonction de la direction de la courbe du centroid, se laissant facilement piéger dans les mouvements latéraux.
En outre, la version améliorée implémente un mécanisme combiné d'arrêt de perte de suivi et d'arrêt de perte fixe pour les sorties.
Bien sûr, l'indicateur de force centroid a des capacités limitées sur les marchés complexes, et les arrêts de trailing peuvent également être pénétrés s'ils sont mal réglés, de sorte que les traders doivent rester alertes et optimiser les paramètres en temps opportun.
