Прорыв по накопленной дельте
Накопленная дельта суммирует разницу между объёмом покупок и продаж. Эта стратегия отслеживает нарастающий итог и входит в рынок, когда он пробивает свой максимум или минимум за выбранный период.
Тестирование показывает среднегодичную доходность около 49%. Стратегию лучше запускать на крипторынке.
Прорыв накопленной дельты часто предшествует продолжению движения цены. Закрытие позиций происходит, когда дельта возвращается через ноль или срабатывает стоп.
Детали
- Условия входа: Накопленная дельта превышает максимальное или минимальное значение за период.
- Длинные/короткие позиции: Оба направления.
- Условия выхода: Дельта пересекает ноль или стоп.
- Стопы: Да.
- Значения по умолчанию:
LookbackPeriod= 20CandleType= TimeSpan.FromMinutes(5)
- Фильтры:
- Категория: Breakout
- Направление: Оба
- Индикаторы: Cumulative Delta
- Стопы: Да
- Сложность: Средняя
- Таймфрейм: Внутридневной
- Сезонность: Нет
- Нейросети: Нет
- Дивергенция: Нет
- Уровень риска: Средний
