Стратегия Logistic RSI STOCH ROC AO

Стратегия применяет логистическое отображение к выбранному индикатору (AO, ROC, RSI, Stochastic) и торгует при пересечении нуля знаковой стандартной девиации.

Детали

  • Критерий входа: Знаковая стандартная девиация пересекает ноль снизу вверх.
  • Лонг/Шорт: Обе стороны.
  • Критерий выхода: Знаковая стандартная девиация пересекает ноль сверху вниз.
  • Стопы: Нет.
  • Значения по умолчанию:
    • Indicator = LogisticDominance
    • Length = 13
    • LenLd = 5
    • LenRoc = 9
    • LenRsi = 14
    • LenSto = 14
    • CandleType = TimeSpan.FromMinutes(1)
  • Фильтры:
    • Категория: Oscillator
    • Направление: Обе
    • Индикаторы: AwesomeOscillator, RateOfChange, RelativeStrengthIndex, StochasticOscillator, Highest
    • Стопы: Нет
    • Сложность: Средняя
    • Таймфрейм: Внутридневной (1м)
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
