Стратегия Forex Line
Стратегия Forex Line основана на индикаторе MetaTrader «ForexLine». Для построения быстрой и медленной линий используется двойное сглаживание цены взвешенными скользящими средними. Пересечения этих линий формируют торговые сигналы.
Покупка выполняется, когда быстрая линия пересекает медленную снизу вверх. Продажа выполняется, когда быстрая линия пересекает медленную сверху вниз. Двойное сглаживание помогает отфильтровать рыночный шум.

- Лонг: быстрая линия пересекает медленную снизу вверх.
- Шорт: быстрая линия пересекает медленную сверху вниз.
- Направление: обе стороны.
- Условия выхода:
- Противоположное пересечение закрывает текущую позицию.
- Стопы: не предусмотрены, можно добавить отдельно.
- Значения по умолчанию:
FastLength1= 5FastLength2= 10SlowLength1= 20SlowLength2= 20CandleType= таймфрейм 8 часов
- Фильтры:
- Категория: следование тренду
- Направление: обе стороны
- Индикаторы: взвешенные скользящие средние
- Стопы: нет
