Стратегия All Divergences

Стратегия All Divergences ищет бычьи и медвежьи дивергенции RSI, фильтруемые трендом скользящей средней. Лонг открывается, когда цена делает новый минимум, а RSI формирует более высокий минимум и цена выше средней. Шорт открывается, когда цена делает новый максимум, а RSI формирует более низкий максимум и цена ниже средней. Дополнительная защита через стоп‑лосс и тейк‑профит может автоматически закрывать позиции, а контроль по скользящей средней завершает сделку после нескольких закрытий против тренда.

Подробности

  • Условия входа:
    • Положение цены относительно скользящей средней определяет тренд.
    • Лонг: цена делает более низкий минимум, RSI – более высокий минимум, цена выше MA.
    • Шорт: цена делает более высокий максимум, RSI – более низкий максимум, цена ниже MA.
  • Направление: обе стороны.
  • Условия выхода:
    • Противоположный сигнал или выход по MA.
  • Стопы: опциональные стоп‑лосс и тейк‑профит.
  • Параметры по умолчанию:
    • MaLength = 50
    • RsiLength = 14
    • MaRiskCandles = 3
    • UseProtection = False
  • Фильтры:
    • Категория: Дивергенция
    • Направление: Обе
    • Индикаторы: RSI, скользящая средняя
    • Стопы: Опционально
    • Сложность: Средняя
    • Таймфрейм: Любой
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Да
    • Уровень риска: Средний
