Стратегия Hammer + EMA с тиковой SL/TP

Сочетает свечные паттерны молот и перевёрнутый молот с трендовым фильтром EMA и тиковой защитой.

Детали

  • Критерии входа: молот над EMA или перевёрнутый молот под EMA.
  • Длинные/короткие: оба направления.
  • Критерии выхода: тик-профит или тик-стоп.
  • Стопы: тиковые.
  • Значения по умолчанию:
    • EmaLength = 50
    • StopLossTicks = 1
    • TakeProfitTicks = 10
    • CandleType = TimeSpan.FromMinutes(1)
  • Фильтры:
    • Категория: Паттерн
    • Направление: Оба
    • Индикаторы: EMA, молот, перевёрнутый молот
    • Стопы: Тиковые
    • Сложность: Базовая
    • Таймфрейм: Внутридневной (1m)
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
