Стратегия разворота на закрытии гэпа
Стратегия Gap Fill Reversal использует ночные гэпы, которые быстро закрываются на следующей сессии. Когда цена отрывается от предыдущего закрытия, но сразу возвращается, чтобы заполнить пустоту, это часто сигнализирует об исчерпании первоначального движения.
Тестирование показывает среднегодичную доходность около 181%. Стратегию лучше запускать на крипторынке.
Стратегия входит после полного закрытия гэпа и рассчитывает на разворот в противоположную сторону открытия. Цель — поймать отскок, когда застрявшие трейдеры выходят из позиций.
Риск ограничивается стопом на основе процента, а позиции закрываются, когда импульс затухает или срабатывает стоп.
