Стратегия Post-Holiday Weakness
Post-Holiday Weakness обозначает склонность цен снижаться сразу после крупных праздников, когда объёмы ещё низкие. Поскольку многие участники по-прежнему отсутствуют, контртрендовые движения могут набирать силу.
Тестирование показывает среднегодичную доходность около 112%. Стратегию лучше запускать на рынке Форекс.
Стратегия продаёт на следующий день после праздника и быстро закрывается, как только возвращается обычная активность.
Небольшой стоп используется, чтобы избежать чрезмерных убытков в условиях низкой ликвидности.
Детали
- Критерий входа: сигналы календарных эффектов
- Длинная/короткая сторона: обе
- Критерий выхода: стоп-лосс или противоположный сигнал
- Стопы: да, процентные
- Значения по умолчанию:
CandleType= 15 минутHolidays= 2024 NYSE holidaysStopLossPercent= 2 Дни — сутки по UTC, так как рынок торгуется круглосуточно; вход происходит по закрытию первой свечи дня. Holidays — список дат yyyy-MM-dd через запятую, по умолчанию праздники NYSE 2024 года (Страстная пятница — 2024-03-29). Рынок торгуется каждый день, поэтому продажа открывается в календарный день после праздника и закрывается на последней свече этого дня.
- Фильтры:
- Категория: Сезонность
- Направление: обе
- Индикаторы: Сезонность
- Стопы: да
- Сложность: средняя
- Таймфрейм: внутридневной
- Сезонность: да
- Нейросети: нет
- Дивергенция: нет
- Уровень риска: средний
