Los mercados suelen respetar las líneas de tendencia trazadas a través de máximos o mínimos anteriores del swing. Esta estrategia ajusta automáticamente líneas de regresión a la acción reciente del precio y busca velas que reboten desde esas líneas en la dirección de la tendencia dominante.
Las pruebas indican un rendimiento anual promedio de aproximadamente el 124%. Funciona mejor en el mercado de divisas.
Las velas recientes se almacenan para calcular líneas de soporte y resistencia de pendiente ascendente o descendente. Cuando el precio se acerca a una línea de tendencia y una vela confirma el rebote mientras permanece en el lado correcto de una media móvil, el sistema abre una operación. El stop se establece usando un porcentaje del precio y la salida ocurre en un cruce de la media móvil.
Al operar solo en la dirección predominante y esperar una reacción clara en soporte o resistencia, el método intenta capturar movimientos de continuación sin perseguir rupturas.
Detalles
Criterios de entrada: El precio toca la línea de tendencia calculada y la vela cierra en la dirección de la tendencia por encima/debajo de la MA.
Largo/Corto: Ambos.
Criterios de salida: Precio cruzando la media móvil o stop-loss.
Stops: Sí, basados en porcentaje.
Valores predeterminados:
TrendlinePeriod = 20
MAPeriod = 20
BounceThresholdPercent = 0.5
CandleType = 5 minute
StopLossPercent = 2
