Стратегия CBC с подтверждением тренда и отдельным стоп-лоссом

Эта стратегия использует состояние смены цвета свечи (CBC) для фиксации пробоя предыдущего максимума или минимума. Вход выполняется при подтверждении тренда через EMA и VWAP и ограничен заданным временным окном. Выход использует тейк-профит на основе ATR и стоп-лосс по экстремумам предыдущей свечи.

Подробности

  • Условия входа: смена CBC, опциональный фильтр сильных сигналов, сравнение медленной EMA с VWAP, торговля в заданные часы.
  • Лонг/Шорт: Оба направления.
  • Условия выхода: тейк-профит по множителю ATR, стоп-лосс на пробой прошлого экстремума.
  • Стопы: Да.
  • Значения по умолчанию:
    • AtrLength = 14
    • ProfitTargetMultiplier = 1.0m
    • StrongFlipsOnly = true
    • EntryStartHour = 10
    • EntryEndHour = 15
    • CandleType = TimeSpan.FromMinutes(5)
  • Фильтры:
    • Категория: Тренд
    • Направление: Оба
    • Индикаторы: EMA, VWAP, ATR
    • Стопы: Да
    • Сложность: Средняя
    • Таймфрейм: Внутридневной
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний

/// CBC with Trend Confirmation and Separate Stop Loss strategy.

/// below the previous candle's low. A flip to bullish goes long when the slow EMA is above the daily VWAP, a flip to bearish goes short
/// when it is below, reversing an opposite position; with StrongFlipsOnly the flip candle also has to close in its direction. Entries
