Parámetros

  • CandleType — marco temporal de las velas.
  • Indicator — indicador a utilizar (MA, MACD, BB).
  • Direction — dirección de la operación (Long o Short).
  • MaLength — período de la media móvil.
  • FastLength — longitud de la EMA rápida del MACD.
  • SlowLength — longitud de la EMA lenta del MACD.
  • SignalLength — longitud de la señal del MACD.
  • BbLength — período de las Bandas de Bollinger.
  • BbMultiplier — multiplicador de las Bandas de Bollinger.
  • StartDate — fecha de inicio.
  • EndDate — fecha de fin.
