Résumé

Il s'agit d'une stratégie de trading quantitative qui utilise deux filtres de tendance. La stratégie combine à la fois le filtre de tendance global et le filtre de tendance local pour s'assurer d'entrer dans les positions uniquement lorsque la direction de tendance est correcte. En outre, la stratégie définit plusieurs autres filtres tels que le filtre RSI, le filtre de prix, le filtre de pente, etc. pour améliorer encore la fiabilité des signaux de trading.

La logique de la stratégie

La logique de base de cette stratégie est basée sur les doubles filtres de tendance. Le filtre de tendance mondiale juge la tendance globale du marché sur la base de l'EMA à haute période, tandis que le filtre de tendance locale juge la tendance locale sur la base de l'EMA à basse période.

Plus précisément, la stratégie calcule l'EMA de BTCUSDT pour déterminer si le marché global est dans une tendance à la hausse ou à la baisse. C'est le filtre de tendance mondiale. En même temps, la stratégie calcule l'EMA du contrat sous-jacent pour déterminer la tendance locale. C'est le filtre de tendance local.

Une fois un signal négociable déterminé, la stratégie va immédiatement placer des ordres pour entrer dans des positions. Pendant ce temps, le prix de stop loss et le prix take profit sont prédéfinis. Lorsque le prix touche l'un d'eux, la stratégie sort automatiquement des positions avec stop loss ou take profit.

Analyse des avantages

Il s'agit d'une stratégie de négociation quantitative stable et fiable qui présente les principaux avantages suivants:

  1. Adoption d'un mécanisme de double filtrage des tendances pour filtrer la plupart des faux signaux et rendre les signaux de trading plus fiables.

  2. Combiner plusieurs filtres auxiliaires comme le filtre RSI et le filtre prix pour améliorer encore la qualité du signal.

  3. Calcul automatique du prix stop loss et du prix take profit pour réduire les risques commerciaux sans surveillance manuelle.

  4. Paramètres de stratégie personnalisables pour adapter plus d'instruments de négociation avec une meilleure adaptabilité.

  5. Une logique stratégique claire, facile à comprendre, et avec un plus grand potentiel d'optimisation.

Analyse des risques

Bien qu'il présente de nombreux avantages, il existe encore certains risques commerciaux principalement dans les domaines suivants:

  1. Les filtres à double tendance peuvent échouer à déterminer le moment exact de l'entrée.

  2. Des paramètres différents peuvent être testés pour trouver l'optimum.

  3. Une mauvaise sélection des instruments de négociation et des délais peut rendre la stratégie inefficace.

  4. Il y a des risques de suradaptation et il est nécessaire d'effectuer davantage de backtests dans divers environnements de marché pour assurer la robustesse.

Directions d'optimisation

Les principales orientations d'optimisation de cette stratégie sont les suivantes:

  1. Ajustez les paramètres des doubles filtres pour trouver la combinaison optimale.

  2. Testez et sélectionnez les meilleurs filtres auxiliaires.

  3. Optimisez les algorithmes de stop loss et de profit pour les rendre plus intelligents.

  4. Essayez d'introduire des modèles d'apprentissage automatique pour le réglage dynamique des paramètres.

  5. Plus de retests sur plus d'instruments et plus de temps pour améliorer la stabilité.

Conclusion

En conclusion, il s'agit d'une stratégie de trading quantitative globale stable, précise et facilement optimisable. Elle produit des signaux de trading en combinant des filtres à double tendance et plusieurs filtres auxiliaires, filtrant la plupart du bruit et générant des signaux plus fiables. En outre, le préréglage de stop loss et take profit intégré aide à réduire les risques de trading. Il s'agit d'une stratégie à grande valeur pratique. Après optimisation et validation, elle peut être directement appliquée au trading en direct. De plus, elle a un énorme potentiel d'expansion et mérite une recherche approfondie.
