Стратегия Rsi Williams R

Реализация стратегии №163 — RSI + Williams %R. Покупка, когда RSI ниже 30 и Williams %R ниже -80 (двойная перепроданность). Продажа, когда RSI выше 70 и Williams %R выше -20 (двойная перекупленность).

Тестирование показывает среднегодичную доходность около 76%. Стратегию лучше запускать на рынке Форекс.

RSI показывает общий импульс, а Williams %R дает более быстрый сигнал разворота. Сделки открываются при согласовании двух осцилляторов.

Подходит активным трейдерам, работающим на коротких движениях. Стоп-лосс задаётся в процентах.

Подробности

  • Условия входа:
    • Длинная: RSI < RsiOversold && WilliamsR < WilliamsROversold
    • Короткая: RSI > RsiOverbought && WilliamsR > WilliamsROverbought
  • Long/Short: Оба
  • Условия выхода:
    • RSI возвращается в нейтральную зону
  • Стопы: процентный уровень через StopLossPercent
  • Параметры по умолчанию:
    • RsiPeriod = 14
    • RsiOversold = 30m
    • RsiOverbought = 70m
    • WilliamsRPeriod = 14
    • WilliamsROversold = -80m
    • WilliamsROverbought = -20m
    • StopLossPercent = 2
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() Нейтральная зона — середина шкалы RSI: лонг закрывается, когда RSI поднимается обратно до 50, шорт — когда опускается до 50. Сигнал на вход против открытой позиции разворачивает её.
  • Фильтры:
    • Категория: Mean reversion
    • Направление: Оба
    • Индикаторы: RSI, Williams %R, R
    • Стопы: Да
    • Сложность: Средняя
    • Таймфрейм: Среднесрочный
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
