Cette stratégie est conçue sur la base des indicateurs TFO (Trend Flex Oscillator) et ATR (Average True Range). Elle est adaptée aux marchés haussiers et ouvre des positions longues lorsque l'action des prix survendus semble inverser. Elle ferme généralement les positions en quelques jours, sauf si elle est prise dans un marché baissier, auquel cas elle se maintient.
Cette stratégie combine les indicateurs TFO et ATR pour déterminer les entrées et les sorties.
Conditions d'entrée: lorsque le TFO tombe en dessous d'un seuil (indiquant des niveaux de survente) et que le TFO a augmenté par rapport à la barre précédente (indiquant un renversement du TFO vers le haut) et que l'ATR est supérieur à un seuil de volatilité fixé (indiquant une volatilité croissante du marché), des positions longues sont ouvertes.
Conditions de sortie: lorsque le TFO dépasse un seuil (indiquant des niveaux de surachat) et que l'ATR dépasse un seuil défini, toutes les positions longues sont fermées.
La stratégie permet jusqu'à 15 positions longues simultanées, les paramètres pouvant être ajustés pour différents délais.
La combinaison de l'analyse des tendances et de la volatilité fournit des signaux stables.
Les paramètres d'entrée, de sortie et de stop loss réglables offrent une flexibilité.
Le stop loss intégré protège contre les mouvements extrêmes.
Le soutien à la pyramide et aux sorties partielles permet de compléter les bénéfices sur les marchés haussiers.
Les marchés baissiers peuvent entraîner des pertes énormes.
Un mauvais réglage des paramètres peut entraîner une survente ou des entrées et sorties manquées.
Dans les mouvements extrêmes, le stop loss peut échouer et ne pas prévenir d'énormes pertes.
Le backtest ne reflète pas pleinement les performances en direct.
Une ligne de stop-loss mobile peut être ajoutée pour des sorties en temps opportun et une meilleure protection à la baisse.
Un mécanisme de shorting peut être ajouté pour permettre des bénéfices lors de baisses du marché lorsque le TFO est inversé à la baisse et que l'ATR est suffisamment élevé.
Plus de filtres comme le changement de volume peuvent réduire les impacts des mouvements erratiques des prix.
Différents délais et paramètres peuvent être testés pour trouver la meilleure combinaison.
Cette stratégie combine les forces de l'analyse de tendance et de volatilité en utilisant TFO et ATR pour déterminer la direction du marché. Des mécanismes tels que la pyramide, la fermeture partielle et le stop loss permettent de compléter les bénéfices tout en contrôlant les risques pendant les marchés haussiers. Il y a place à des améliorations via plus de filtres d'indicateurs et d'optimisation des paramètres.
