Индикатор Williams %R
Стратегия основана на показателе Williams %R.
Тестирование показывает среднегодичную доходность около 88%. Стратегию лучше запускать на фондовом рынке.
Williams %R определяет зоны перекупленности и перепроданности. Когда индикатор поднимается выше верхнего порога, это сигнал о возможной слабости и повод для коротких позиций; значения ниже нижнего порога указывают на покупки. Позиции закрываются, когда %R возвращается к нейтральной зоне.
Так как %R быстро колеблется, стратегия может давать много сигналов на волатильных рынках. Некоторые трейдеры комбинируют его с другими фильтрами для уменьшения шума.
