Стратегия разворота по автокорреляции
Стратегия анализирует краткосрочную автокорреляцию цены, чтобы оценить вероятность разворота последнего движения. Отрицательная автокорреляция означает, что последовательные изменения цены склонны чередоваться, создавая условия для возврата к среднему.
Тестирование показывает среднегодичную доходность около 124%. Стратегию лучше запускать на рынке Форекс.
Когда вычисленная автокорреляция опускается ниже порога и цена находится ниже скользящей средней, система покупает в ожидании отскока. Если автокорреляция отрицательная и цена выше средней, открывается короткая позиция. Выход происходит, когда цена пересекает среднюю или автокорреляция поднимается выше порога.
Подход предназначен для трейдеров, ищущих статистические преимущества, а не графические паттерны. Для защиты от устойчивого тренда применяется процентный стоп‑лосс.
