Стратегия Pivot Heiken

Стратегия объединяет дневные уровни Pivot и свечи Heikin-Ashi с опциональным трейлинг-стопом. Дневной пивот рассчитывается по максимуму, минимуму и закрытию предыдущего дня. Свечи Heikin-Ashi сглаживают шум и подчёркивают направление тренда.

Логика

  • Вход в лонг: свеча Heikin-Ashi бычья и закрытие выше дневного пивота.
  • Вход в шорт: свеча Heikin-Ashi медвежья и закрытие ниже дневного пивота.
  • Выход: по стоп-лоссу, тейк-профиту или уровню трейлинг-стопа.

Параметры

  • CandleType – рабочая серия свечей.
  • StopLossPips – расстояние стоп-лосса в пунктах.
  • TakeProfitPips – расстояние тейк-профита в пунктах.
  • TrailingStopPips – размер трейлинг-стопа в пунктах (0 отключает трейлинг).

Индикаторы

  • Heikin-Ashi (рассчитывается внутри стратегии).
  • Дневной пивот.

Примечания

  • Используется высокоуровневый API с подпиской на свечи и обработчиками индикаторов.
  • Подходит для торговли в обе стороны.
