Стратегия Fibonacci TP SL

Эта стратегия использует уровни коррекции Фибоначчи для входа в позицию, устанавливая стоп-лосс на основе ATR и тейк-профит в процентах. Торговля ограничена минимальным интервалом между сделками и недельным ограничением прибыли.

Детали

  • Условия входа:

    • Лонг: Close <= Fib 38.2% && Close >= Fib 78.6% && Минимальное количество баров с последней сделки
    • Шорт: Close <= Fib 23.6% && Close >= Fib 61.8% && Минимальное количество баров с последней сделки

  • Направление: Обе стороны

  • Условия выхода:

    • ATR стоп-лосс или Тейк-профит

  • Стопы: Да

  • Значения по умолчанию:

    • Take Profit % = 4
    • Min Bars Between Trades = 10
    • Lookback = 100
    • ATR Period = 14
    • ATR Multiplier = 1.5
    • Max Weekly Return = 0.15

  • Фильтры:

    • Категория: Среднее возвращение
    • Направление: Обе
    • Индикаторы: Highest, Lowest, ATR
    • Стопы: Да
    • Сложность: Низкая
    • Таймфрейм: Любой
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
