Hola Nicolas,he encontrado este interesante Trailing-Stop basado en el ATR.¿Sería usted tan amable de traducirlo?.Gracias

/////////notes////////////////////////////////////////
// This is based on the ATR trailing stop indicator //
// width addition of two levels of stops and //
// different interpretation. //
// This is a fast-reacting system and is better //
// suited for higher volatility markets //
