Бот на основе уровней Фибоначчи

Стратегия использует уровни коррекции Фибоначчи для поиска свинговых движений.

Бот вычисляет уровни 0.618 и 0.786 от диапазона последних 50 свечей и открывает позиции при пробое этих уровней. Управление риском осуществляется через параметры стоп-лосса и соотношения риск/прибыль.

Детали

  • Критерии входа: ценовое действие и уровни Фибоначчи.
  • Длинные/короткие: оба направления.
  • Критерии выхода: стоп-лосс или тейк-профит.
  • Стопы: да, процентные.
  • Значения по умолчанию:
    • FiboLevel1 = 0.618
    • FiboLevel2 = 0.786
    • RiskRewardRatio = 2
    • StopLossPercent = 1
    • CandleType = TimeSpan.FromHours(4)
  • Фильтры:
    • Категория: Свинг
    • Направление: Оба
    • Индикаторы: Фибоначчи, Дончиан
    • Стопы: Да
    • Сложность: Средняя
    • Таймфрейм: 4ч
    • Сезонность: Нет
    • Нейросети: Нет
    • Дивергенция: Нет
    • Уровень риска: Средний
