Estrategia MA Parabolic SAR
La estrategia MA Parabolic SAR intenta capturar tendencias sostenidas utilizando una media móvil para determinar la dirección prevaleciente y los puntos Parabolic SAR para el momento de entrada y la colocación del stop. Cuando ambos indicadores se alinean, el sistema asume que el momentum es suficientemente fuerte para seguirlo.
Las pruebas indican un rendimiento anual promedio de aproximadamente 76%. Funciona mejor en el mercado de divisas.
Se abre una posición larga cuando el precio de cierre está por encima de la media móvil y los puntos Parabolic SAR se invierten por debajo del mercado. Se toma una posición corta cuando el precio está por debajo de la media y los puntos SAR se invierten por encima del precio, señalando presión bajista. La estrategia sale una vez que el precio cruza el SAR en dirección opuesta, asegurando ganancias o limitando pérdidas.
Este enfoque es más adecuado para traders que prefieren el seguimiento sistemático de tendencias con stops claros y mecánicos. El Parabolic SAR se ajusta continuamente a medida que cambia la volatilidad, manteniendo la exposición en línea con las condiciones del mercado mientras que la media móvil evita las operaciones contra la tendencia más amplia.
Detalles
- Criterios de entrada:
- Largo: Price > MA && Price > Parabolic SAR
- Corto: Price < MA && Price < Parabolic SAR
- Largo/Corto: Ambos lados.
- Criterios de salida:
- Largo: Salir cuando el precio cae por debajo del Parabolic SAR
- Corto: Salir cuando el precio sube por encima del Parabolic SAR
- Stops: Sí, dinámico vía Parabolic SAR y stop fijo opcional.
- Valores predeterminados:
MaPeriod = 20
SarStep = 0.02
SarMaxStep = 0.2
CandleType = TimeSpan.FromMinutes(5)
StopLossPercent = 2
Una entrada necesita ambas condiciones al cierre de una vela, sea el giro del SAR o el cruce de la MA lo que ocurra último. El stop fijo opcional es StopLossPercent del precio de entrada, vigilado también entre velas; 0 lo desactiva. Las reglas no fijan objetivo de beneficio, por lo que se eliminó el TakeValue nulo. Una señal de entrada contra una posición abierta la invierte.
