Стратегия 3-Bar Low
Стратегия 3-Bar Low открывает длинную позицию, когда цена закрытия опускается ниже минимума предыдущих трёх баров, и выходит из позиции, когда цена закрытия поднимается выше максимума предыдущих семи баров. Дополнительный фильтр EMA может требовать, чтобы цена находилась выше долгосрочного среднего перед входом в сделку.
Подробности
- Условия входа:
- Цена закрытия ниже предыдущего минимума за три бара.
- Опционально: цена закрытия выше EMA при включенном фильтре.
- Направление: Только лонг.
- Условия выхода:
- Цена закрытия выше предыдущего максимума за семь баров.
- Стопы: Нет.
- Параметры по умолчанию:
MaPeriod= 200LowestLength= 3HighestLength= 7UseEmaFilter= false
- Фильтры:
- Категория: Пробой
- Направление: Лонг
- Индикаторы: EMA, Highest/Lowest
- Стопы: Нет
- Сложность: Низкая
- Таймфрейм: Любой
- Сезонность: Нет
- Нейросети: Нет
- Дивергенция: Нет
- Уровень риска: Низкий
