Utiliza el indicador Parabolic SAR con paso y aceleración máxima configurables.
Compra cuando el precio cierra por encima del SAR y previamente estaba por debajo.
Vende cuando el precio cierra por debajo del SAR y previamente estaba por encima.
El parámetro de reversión opcional invierte las señales de compra/venta.
La opción SarClose cierra la posición existente cuando el SAR cambia al lado opuesto.
Distancias fijas de take-profit y stop-loss en unidades de precio. Se puede activar el trailing stop.
Parámetros
SarStep – paso del factor de aceleración.
SarMax – factor de aceleración máximo.
StopLoss – distancia inicial del stop-loss.
TakeProfit – distancia del take-profit.
Trailing – activar trailing stop.
TrailStop – distancia del trailing stop cuando está activado.
SarClose – cerrar posición en reversión del SAR.
Reverse – invertir señales de trading.
CandleType – tipo de vela para los cálculos.
Notas
La estrategia usa la API de alto nivel con suscripciones a velas y vinculación de indicadores. La protección se inicia con trailing stop opcional y salidas con órdenes de mercado.
