Cette stratégie utilise un réseau neuronal artificiel (ANN) pour prédire les changements de prix futurs et génère des signaux de trading basés sur les prédictions. Elle appartient à la stratégie de suivi des tendances.
La stratégie utilise un modèle ANN pour prédire la variation en pourcentage du jour de négociation suivant.
La couche d'entrée n'a qu'un seul nœud, qui est le changement en pourcentage de la journée précédente.
La couche cachée a 2 couches, la première avec 5 nœuds, et la seconde avec 33 nœuds.
La couche de sortie a un nœud, passant par une fonction d'activation linéaire pour générer la prédiction finale.
Si la prédiction est supérieure au paramètre de seuil, un signal long est généré.
Cette stratégie basée sur ANN peut identifier des tendances non linéaires complexes et convient au trading à moyen et long terme. Cependant, la nature de la boîte noire des modèles ANN pose également des défis importants pour le trading en direct. Nous devons optimiser les fonctionnalités d'entrée, l'architecture du modèle, le réglage des paramètres, l'apprentissage ensemble, etc. tout en combinant avec l'analyse technique traditionnelle pour des performances robustes dans le monde réel.
