Стратегия Следования Тренду по Классам Активов

Эта стратегия отслеживает тренды в разных классах активов. Для каждого инструмента из вселенной применяется простой скользящий средний фильтр. Портфель ребалансируется в первый торговый день месяца, а позиции открываются только если цена выше скользящей средней.

Тестирование показывает среднегодовую доходность около 15%. Наилучшие результаты достигаются на диверсифицированных портфелях фьючерсов.

В начале каждого месяца инструментам, чья цена выше SMA, присваивается равная доля капитала. Позиции закрываются при падении цены ниже SMA или при перераспределении капитала.

Детали

  • Условия входа: Close > SMA
  • Длинные/короткие: Только длинные
  • Условия выхода: Close <= SMA или исключение при ребалансировке
  • Стопы: Нет; капитал перераспределяется ежемесячно
  • Параметры по умолчанию:
    • SmaLength = 210
    • MinTradeUsd = 50
    • CandleType = дневные свечи
  • Фильтры:
    • Категория: Следование тренду
    • Направление: Только long
    • Индикаторы: SMA
    • Стопы: Нет
    • Сложность: Средняя
    • Таймфрейм: Долгосрочный
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
