Стратегия дивергенции по Williams %R
Осциллятор Williams %R оценивает зоны перекупленности и перепроданности. Когда цена делает новый минимум, а %R формирует более высокий минимум, или когда цена обновляет максимум, но %R снижается, возможен разворот. Эта стратегия ищет такие дивергенции на экстремумах индикатора.
Тестирование показывает среднегодичную доходность около 109%. Стратегию лучше запускать на крипторынке.
Каждый бар система записывает последнее закрытие и значение %R для сравнения с предыдущим. Бычья дивергенция в сочетании с уровнем ниже -80 открывает длинную позицию, а медвежья и значение выше -20 — короткую. Стопы устанавливаются как процент от цены.
Позиции закрываются, когда индикатор возвращается к противоположному экстремуму, фиксируя откат после сигнала дивергенции.
