Cette stratégie utilise les rails supérieurs et inférieurs des bandes de Bollinger pour mettre en œuvre un stop loss dynamique. Il va court lorsque le prix traverse le rail supérieur et va long lorsque le prix traverse le rail inférieur. Et il définit un stop loss dynamique pour suivre le mouvement du prix.
Le noyau de cette stratégie réside dans les rails supérieurs et inférieurs des bandes de Bollinger.déviation type de n jours. Le rail inférieur est le rail du milieu − kLorsque le prix rebondit du rail inférieur, allez long. Lorsque le prix retombe du rail supérieur, allez court. Dans le même temps, la stratégie fixe un point de stop-loss et l'ajuste dynamiquement pendant le mouvement du prix pour définir un point de profit pour mettre en œuvre un contrôle prudent des risques.
Cette stratégie utilise les attributs de régression des bandes de Bollinger ainsi que le stop-loss glissant dynamique pour obtenir des profits de tendance à moyen et long terme tout en contrôlant les risques.
