Стратегия MartinGale Scalping

Пересечение SMA(3) и SMA(8) запускает входы с мартингейловым пирамидингом. Дополнительные заявки добавляются на каждом баре до срабатывания стопа или тейка.

Детали

  • Условия входа: SMA3 выше SMA8 для лонга, ниже для шорта; новые входы добавляются пока сигнал сохраняется.
  • Длинные/Короткие: регулируется параметром TradingMode.
  • Условия выхода: достижение TakeProfit или StopLoss и противоположное положение SMA.
  • Стопы: да, на основе медленной SMA.
  • Значения по умолчанию:
    • FastLength = 3
    • SlowLength = 8
    • TakeProfit = 1.03
    • StopLoss = 0.95
    • TradingMode = Long
    • CandleType = 5 минут
    • MaxPyramids = 5
  • Фильтры:
    • Категория: Trend
    • Направление: Задаётся
    • Индикаторы: SMA
    • Стопы: Да
    • Сложность: Новичок
    • Таймфрейм: Внутридневной
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Риск: Высокий
