Стратегия LSMA Angle
Стратегия использует угол скользящей средней наименьших квадратов (LSMA) для определения направления тренда. Угол приближенно вычисляется как разность между двумя значениями LSMA, разделёнными заданным количеством баров.
- Лонг: угол LSMA поднимается выше положительного порога.
- Выход из лонга: угол опускается ниже положительного порога.
- Шорт: угол LSMA падает ниже отрицательного порога.
- Выход из шорта: угол поднимается выше отрицательного порога.
Параметры
LSMA Period: длина расчёта LSMA.Angle Threshold: абсолютное значение нейтральной зоны вокруг нуля.Start Shift: более старый бар для вычисления угла.End Shift: более новый бар для вычисления угла.Candle Type: тип свечей для расчёта.
Примечания
- Значения угла масштабируются в пункты в зависимости от инструмента (1000 для пар с JPY, иначе 100000).
- Используются только завершённые свечи.
