La stratégie Turtle Trend est une version améliorée de la célèbre stratégie Turtle Trading. Elle utilise les signaux de trading générés par les doubles moyennes mobiles pour mettre en œuvre une tendance à faible risque après le trading.
Après être entré sur le marché, la stratégie utilise les valeurs ATR pour définir le stop loss et la cible pyramidale. Elle s'arrête lorsque les pertes atteignent le niveau de stop loss et augmente la taille de la position lorsque les bénéfices atteignent la cible pyramidale. Cela maximise le potentiel de profit sur les marchés tendance tout en contrôlant les risques des transactions individuelles.
Le plus grand avantage de la stratégie Turtle Trend réside dans ses excellentes capacités de contrôle des risques. Les règles d'entrée et de sortie standardisées peuvent contrôler efficacement les pertes des transactions individuelles. Le mécanisme de saut évite d'être coincé dans des conditions de marché défavorables. La stratégie de stop loss stable limite également les pertes consécutives.
En outre, la stratégie Turtle Trend utilise l'indicateur ATR pour régler dynamiquement le stop loss, permettant à la ligne de stop loss de s'adapter automatiquement aux changements de volatilité du marché.
Enfin, le mécanisme pyramidal permet à la stratégie de saisir pleinement les bénéfices sur les marchés en tendance, jetant les bases d'une croissance régulière du capital.
Le principal risque de la stratégie Turtle Trend est qu'elle ne parvient pas à tirer profit des marchés à plage. Lorsque le marché fluctue dans une plage pendant de longues périodes, un stop loss peut souvent être déclenché, ce qui entraîne des pertes.
En outre, la dépendance excessive aux indicateurs techniques fait abstraction de l'analyse des fondamentaux, qui peut ne pas détecter les changements majeurs de politique et entraîner des pertes inutiles.
La stratégie Turtle Trend peut être optimisée dans les aspects suivants:
Ajuster la sensibilité du mécanisme de saut en combinant des indicateurs de volatilité pour augmenter la fréquence des transactions sur différents marchés.
Ajouter des signaux fondamentaux comme filtre pour éviter d'être frappé par un stop loss en raison d'événements sporadiques.
Optimiser les paramètres de l'ATR pour que la ligne stop-loss adhère plus étroitement à la fluctuation réelle.
Combiner les indicateurs de volume pour éviter une reprise inefficace après une perte.
En résumé, Turtle Trend Strategy améliore la rentabilité et les capacités de contrôle des risques de la stratégie de trading Turtle originale. C'est une stratégie algorithmique à faible risque adaptée au suivi des marchés en tendance. Avec une optimisation supplémentaire, elle peut devenir un élément important de la construction d'un portefeuille rentable stable à long terme.
