Стратегия ALMA & UT Bot Confluence

Стратегия ALMA & UT Bot Confluence сочетает фильтр Arnaud Legoux Moving Average с трейлинг-стопом в стиле UT Bot. Длинная позиция открывается, когда цена выше долгосрочной EMA и ALMA, объём превышает своё среднее, RSI подтверждает импульс, ADX показывает силу тренда, свеча ниже верхней полосы Боллинджера и UT Bot даёт сигнал на покупку. Короткие позиции открываются при переходе UT Bot в медвежий режим и пересечении цены ниже быстрой EMA при соблюдении тех же фильтров. Выходы осуществляются либо по трейлинг-стопу UT Bot, либо по фиксированным ATR-ориентированным стоп-лоссу и тейк-профиту.

Подробности

  • Условия входа:
    • Лонг: цена > EMA и ALMA, RSI > 30, ADX > 30, цена < верхней полосы Боллинджера, сигнал покупки UT Bot, фильтры объёма и ATR, период охлаждения.
    • Шорт: пересечение цены ниже быстрой EMA с сигналом продажи UT Bot и фильтрами.
  • Направление: лонг/шорт.
  • Условия выхода:
    • Трейлинг-стоп UT Bot или стоп-лосс/тейк-профит на основе ATR и необязательный выход по времени.
  • Стопы: ATR или трейлинг.
  • Параметры по умолчанию:
    • FastEmaLength = 20
    • EmaLength = 72
    • AtrLength = 14
    • AdxLength = 10
    • RsiLength = 14
    • BbMultiplier = 3.0
    • StopLossAtrMultiplier = 5.0
    • TakeProfitAtrMultiplier = 4.0
    • UtAtrPeriod = 10
    • UtKeyValue = 1
    • VolumeMaLength = 20
    • BaseCooldownBars = 7
    • MinAtr = 0.005
  • Фильтры:
    • Категория: следование тренду с фильтром волатильности
    • Направление: лонг/шорт
    • Индикаторы: EMA, ALMA, ADX, RSI, полосы Боллинджера, UT Bot
    • Стопы: ATR или трейлинг
    • Сложность: высокая
    • Таймфрейм: любой
    • Сезонность: нет
    • Нейросети: нет
    • Дивергенция: нет
    • Уровень риска: средний
