Стратегия Highs Lows

Стратегия торгует на основе средних точек свечей относительно диапазона максимумов и минимумов.

Покупает, когда средняя текущей свечи ниже среднего между максимумом и минимумом, и нормализованное расстояние меньше LowThreshold. Закрывает длинную позицию, когда средняя выше этого значения и нормализованное расстояние превышает HighThreshold.

Детали

  • Критерии входа: Средняя свечи ниже диапазона и нормализованное расстояние ниже LowThreshold.
  • Длинные/короткие: только длинные.
  • Критерии выхода: Средняя выше диапазона и нормализованное расстояние выше HighThreshold.
  • Стопы: нет.
  • Значения по умолчанию:
    • Range = 100
    • LowThreshold = 15m
    • HighThreshold = 85m
    • CandleType = TimeSpan.FromMinutes(240)
  • Фильтры:
    • Категория: Диапазон
    • Направление: Длинные
    • Индикаторы: Highest, Lowest
    • Стопы: Нет
    • Сложность: Базовая
    • Таймфрейм: Внутридневной (240m)
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
