Триггер по VIX

Стратегия реагирует на изменения индекса волатильности VIX. Рост VIX сигнализирует страх и возможные развороты базового инструмента. Система сравнивает направление VIX с положением цены относительно скользящей средней.

Тестирование показывает среднегодичную доходность около 148%. Стратегию лучше запускать на рынке Форекс.

Когда VIX растёт и цена ниже средней, открывается длинная позиция в ожидании восстановления. Напротив, растущий VIX при цене выше средней предполагает короткую позицию.

Позиции закрываются при снижении VIX или достижении стоп-процента.

Подробности

  • Условия входа: рост VIX и положение цены относительно MA задают лонг или шорт.
  • Длинные/короткие позиции: обе стороны.
  • Условия выхода: снижение VIX или стоп.
  • Стопы: да.
  • Значения по умолчанию:
    • MAPeriod = 20
    • StopLossPercent = 2.0m
    • CandleType = TimeSpan.FromMinutes(5)
  • Фильтры:
    • Категория: Contrarian
    • Направление: обе стороны
    • Индикаторы: VIX, MA
    • Стопы: да
    • Сложность: средняя
    • Таймфрейм: внутридневной
    • Сезонность: нет
    • Нейросети: нет
    • Дивергенция: нет
    • Уровень риска: средний
