VWAP: средневозврат по наклону
Стратегия VWAP Slope Mean Reversion сосредоточена на экстремальных значениях индикатора VWAP, чтобы использовать возврат к среднему. Широкие отклонения от нормального уровня редко продолжаются долго.
Сделки открываются, когда индикатор значительно отклоняется от своего среднего значения и начинает разворачиваться. Вход в длинные и короткие позиции сопровождается защитным стопом.
Подходит свинг‑трейдерам, ожидающим колебаний; стратегия закрывает позицию, когда VWAP возвращается к равновесию. Начальное значение SlopeLookback = 20.
Детали
- Условия входа: Индикатор разворачивается в сторону среднего значения.
- Длинные/Короткие: Оба направления.
- Условия выхода: Индикатор возвращается к среднему.
- Стопы: Да.
- Значения по умолчанию:
SlopeLookback= 20ThresholdMultiplier= 2mStopLossPercent= 2mCandleType= TimeSpan.FromMinutes(5)
- Фильтры:
- Категория: Средневозвратная
- Направление: Оба
- Индикаторы: VWAP
- Стопы: Да
- Сложность: Средняя
- Таймфрейм: Краткосрочный
- Сезонность: Нет
- Нейросети: Нет
- Дивергенция: Нет
- Уровень риска: Средний
