La stratégie combine un graphique de volume et des prix en temps réel pour générer des signaux d’achat et de vente en analysant les prix et la distribution du volume d’achat sur une période donnée. La stratégie calcule d’abord plusieurs niveaux de prix en fonction du prix actuel et du pourcentage de la fourchette de prix définie.
Cette stratégie a pour avantage de pouvoir visualiser la distribution des prix et des volumes de transactions et de prendre en compte de multiples facteurs pour générer des signaux. Cependant, la stratégie présente également des limites et des risques, tels que l’impact des paramètres, le retard des indicateurs, la dépendance à la tendance du marché. Par conséquent, dans la pratique, il est nécessaire d’optimiser et de perfectionner davantage la stratégie, comme l’introduction de plus d’indicateurs, l’optimisation des conditions de signal, le renforcement des contrôles de risque, etc.
