Il s’agit d’un système de négociation automatique basé sur une moyenne sans fil de la ligne K ((Heikin-Ashi) et un prix moyen pondéré par le volume de transaction ((VWAP)). La stratégie consiste à identifier des formes spécifiques de la ligne K, en combinaison avec VWAP comme support / résistance dynamique, pour effectuer des opérations d’achat et de vente dans le temps de négociation défini. Le système utilise un point de perte de stop fixe pour gérer le risque et forcer le plafonnement à des heures spécifiques par jour pour éviter le risque du jour au lendemain.
La logique fondamentale de la stratégie repose sur les éléments clés suivants :
La stratégie, combinant les indicateurs Heikin-Ashi et VWAP, a permis de construire un système de trading intraday robuste. Bien qu’il y ait de la place pour l’optimisation, le cadre de base est très pratique. Grâce à l’orientation de l’optimisation proposée, la stratégie est susceptible de mieux fonctionner dans différentes conditions de marché. L’accent est mis sur l’ajustement minutieux des paramètres en fonction des caractéristiques de chaque variété de trading.
