Стратегия MA Crossover Demand Supply Zones SLTP

Стратегия сочетает пересечение короткой и длинной простых скользящих средних с определением зон спроса и предложения. Сигналы появляются, когда пересечение происходит рядом с подтверждённой зоной, после чего позиция управляется по процентным стоп-лоссу и тейк-профиту.

Детали

  • Условия входа:
    • Лонг: короткая SMA пересекает длинную сверху возле зоны спроса.
    • Шорт: короткая SMA пересекает длинную снизу возле зоны предложения.
  • Направление: Обе стороны.
  • Условия выхода:
    • Срабатывание стоп-лосса или тейк-профита.
  • Стопы: Процентные стоп-лосс и тейк-профит.
  • Значения по умолчанию:
    • ShortMaLength = 9
    • LongMaLength = 21
    • ZoneLookback = 50
    • ZoneStrength = 2
    • StopLossPercent = 1
    • TakeProfitPercent = 2
  • Фильтры:
    • Категория: Следование тренду
    • Направление: Обе
    • Индикаторы: SMA, Highest, Lowest
    • Стопы: Да
    • Сложность: Базовая
    • Таймфрейм: Любой
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
