Стратегия Macd Momentum Reversal

Стратегия использует гистограмму MACD для поиска разворота момента. Продаёт, когда бычья свеча увеличивается, а гистограмма MACD снижается. Покупает, когда медвежья свеча увеличивается, а гистограмма MACD растёт.

Подробности

  • Критерии входа: увеличенное тело свечи и ослабевающий импульс MACD.
  • Длинные/короткие: оба направления.
  • Критерии выхода: противоположный сигнал.
  • Стопы: нет.
  • Параметры по умолчанию:
    • FastLength = 12
    • SlowLength = 26
    • SignalLength = 9
    • CandleType = TimeSpan.FromMinutes(1)
  • Фильтры:
    • Категория: Импульс
    • Направление: Оба
    • Индикаторы: MACD
    • Стопы: Нет
    • Сложность: Базовая
    • Таймфрейм: Внутридневной (1м)
    • Сезонность: Нет
    • Нейронные сети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
