ChartArt

Полосы Боллинджера — это популярный инструмент технического анализа, разработанный Джоном Боллинджером в начале 1980-х гг. Индикатор состоит из трёх полос, рассчитанных относительно цены торгового инструмента. Средняя линия, как правило, выражена 20-дневным простым скользящим средним (SMA) (тип и период линии могут быть изменены трейдером; однако приведенные значения наиболее популярны). SMA служит базовой линией для верхних и нижних полос, которые используются для измерения волатильности, учитывая отношение между полосами и ценой. Верхняя и нижняя полосы рассчитаны как два стандартных отклонения к значению средней линии, однако, это значение также может быть изменено трейдером.
