Прорыв канала Келтнера
Стратегия основана на прорыве канала Келтнера.
Тестирование показывает среднегодичную доходность около 58%. Стратегию лучше запускать на фондовом рынке.
Каналы строятся с использованием ATR. Прорыв выше верхней полосы или ниже нижней вызывает вход. Выход происходит, когда цена возвращается через EMA в центре канала или срабатывает стоп.
Так как полосы расширяются и сужаются в зависимости от волатильности, метод позволяет поймать ранние стадии сильного движения, оставляя цене пространство внутри канала.
Детали
- Критерии входа: сигналы на основе ATR, Keltner.
- Длинные/короткие: оба направления.
- Критерии выхода: противоположный сигнал или стоп.
- Стопы: да.
- Значения по умолчанию:
EmaPeriod= 20AtrPeriod= 14AtrMultiplier= 2mCandleType= TimeSpan.FromMinutes(5)
- Фильтры:
- Категория: Прорыв
- Направление: Оба
- Индикаторы: ATR, Keltner
- Стопы: Да
- Сложность: Базовая
- Таймфрейм: Внутридневной (5m)
- Сезонность: Нет
- Нейросети: Нет
- Дивергенция: Нет
- Уровень риска: Средний
