Прорыв наклона OBV
Стратегия OBV Slope Breakout отслеживает скорость изменения индикатора OBV. Сильный рост наклона подсказывает возможное формирование нового тренда.
Тестирование показывает среднегодичную доходность около 154%. Стратегию лучше запускать на фондовом рынке.
Сделка открывается, когда наклон превышает свой обычный уровень на несколько стандартных отклонений. Позиция открывается в направлении ускорения со стопом.
Она подходит активным трейдерам, стремящимся рано войти в тренд. Позиции закрываются, когда наклон возвращается к нормальным значениям. Значение по умолчанию LookbackPeriod = 20.
