Стратегия разворота по Williams %R Hook
Стратегия Williams %R Hook Reversal отслеживает индикатор Williams %R, который быстро отскакивает от экстремального значения. Когда значение выходит выше -20 или ниже -80 и затем поворачивает к центру, прежний импульс, как правило, исчерпан.
Тестирование показывает среднегодичную доходность около 172%. Стратегию лучше запускать на рынке Форекс.
Стратегия покупает, когда %R разворачивается вверх из зоны перепроданности, тогда как цена обновляет минимум, и продаёт, когда индикатор загибается вниз из зоны перекупленности при формировании нового максимума.
Жёсткий процентный стоп контролирует риск, а сделки закрываются, когда %R зацепляется в обратную сторону или срабатывает стоп.
