Estrategia Genie RSI

Esta estrategia opera reversiones de sobrecompra y sobreventa usando el Índice de Fuerza Relativa (RSI). Cuando el RSI sube por encima de 80 la estrategia abre una posición corta; cuando el RSI cae por debajo de 20 abre una posición larga. Niveles opcionales de take profit y stop trailing gestionan el riesgo después de la entrada.

La estrategia está diseñada para mercados oscilantes donde el precio se mueve frecuentemente entre soporte y resistencia. Funciona en cualquier marco temporal, definido por el parámetro CandleType.

Detalles

  • Criterios de entrada
    • Largo: El valor del RSI cruza por debajo de 20 en una vela finalizada y no hay posición abierta.
    • Corto: El valor del RSI cruza por encima de 80 en una vela finalizada y no hay posición abierta.
  • Criterios de salida
    • Largo: El RSI sube por encima de 80, el precio alcanza la distancia de take profit, o el precio toca el nivel de stop trailing.
    • Corto: El RSI cae por debajo de 20, el precio alcanza la distancia de take profit, o el precio toca el nivel de stop trailing.
  • Indicadores: RSI.
  • Parámetros:
    • RSI Period – longitud del indicador RSI.
    • Take Profit – distancia en unidades de precio para el objetivo de ganancia.
    • Trailing Stop – distancia en unidades de precio para el stop trailing.
    • Candle Type – marco temporal de las velas procesadas.
  • Gestión de posición: Usa órdenes de mercado para entradas y salidas. El stop trailing se recalcula en cada vela finalizada.
