Il s'agit d'une stratégie de trading basée sur le principe de croisement de la moyenne mobile exponentielle (EMA).
Il s'agit d'une stratégie globale solide pour construire un système de trading EMA complet, avec une confirmation RSI supplémentaire pour améliorer la qualité du signal. Il vaut la peine d'être étudié et optimisé. Cependant, les risques inhérents au décalage des indicateurs doivent également être gérés par un stop loss approprié.
