Cette stratégie identifie et suit les tendances en construisant un canal de prix pour calculer l'écart du prix par rapport à la ligne médiane et en utilisant des moyennes mobiles pour filtrer les signaux.
La stratégie est globalement assez robuste pour suivre efficacement les tendances à moyen et long terme tout en générant des signaux de trading par le biais de ruptures de tendance.
