Стратегия Fractal WPR
Стратегия использует осциллятор Williams %R для генерации торговых сигналов при пересечении границ зон перекупленности и перепроданности. Она адаптирована из советника MQL5 и демонстрирует простой подход к торговле на разворотах импульса.
Как это работает
- Рассчитывается индикатор Williams %R с настраиваемым периодом на выбранном таймфрейме.
- Две горизонтальные линии задают экстремальные зоны:
HighLevelобозначает область перекупленности (по умолчанию −30).LowLevelобозначает область перепроданности (по умолчанию −70).
- При параметре
Trend = Direct:- Пробой вниз уровня
LowLevelоткрывает длинную позицию и закрывает все короткие. - Пробой вверх уровня
HighLevelоткрывает короткую позицию и закрывает все длинные.
- Пробой вниз уровня
- При
Trend = Againstреакции на пересечения меняются местами. - Дополнительные параметры позволяют отдельно разрешать или запрещать открытие и закрытие длинных и коротких позиций.
- Для защиты используются стоп‑лосс и тейк‑профит, задаваемые в тиках и подключаемые через высокоуровневый API.
Обрабатываются только завершённые свечи, что исключает влияние внутридневного шума.
Параметры
WprPeriod– период расчёта Williams %R.HighLevel– порог зоны перекупленности.LowLevel– порог зоны перепроданности.Trend– режим торговли (DirectилиAgainst).BuyPositionOpen– разрешить открытие длинных позиций.SellPositionOpen– разрешить открытие коротких позиций.BuyPositionClose– разрешить закрытие длинных позиций.SellPositionClose– разрешить закрытие коротких позиций.StopLossTicks– расстояние стоп‑лосса в тиках.TakeProfitTicks– расстояние тейк‑профита в тиках.CandleType– таймфрейм свечей для анализа.
