Estrategia de Fuerza de Bias y Sentimiento

Esta estrategia agrega múltiples indicadores de momentum y volumen (MACD, RSI, Stochastic, Awesome Oscillator, promedios Alligator y bias de volumen) en un único valor de bias. Se abre una posición larga cuando el bias combinado está por encima de cero y una posición corta cuando está por debajo de cero.

Detalles

  • Criterios de entrada:
    • Largo: Bias combinado > 0.
    • Corto: Bias combinado < 0.
  • Largo/Corto: Ambos.
  • Criterios de salida: Señal inversa.
  • Stops: Porcentaje de stop-loss mediante StopLossPercent.
  • Valores predeterminados:
    • MACD rápido 12, lento 26, señal 9.
    • Período RSI 14.
    • Períodos Stochastic 21/14/14.
    • Períodos Awesome Oscillator 5/34.
    • Longitud de bias de volumen 30.
  • Filtros:
    • Categoría: Seguimiento de tendencia
    • Dirección: Ambos
    • Indicadores: Múltiples
    • Stops: Sí
    • Complejidad: Complejo
    • Marco temporal: Medio plazo
