Внутридневная стратегия импульса

Торгуется в заданной сессии, используя пересечение EMA, фильтр RSI и подтверждение VWAP. Открывает лонг при пересечении быстрой EMA выше медленной, когда RSI ниже уровня перекупленности и цена выше VWAP. Шорт открывается при противоположных условиях. Используются фиксированные проценты стоп-лосса и тейк-профита, а в конце сессии позиции закрываются.

Параметры

  • EmaFastLength: период быстрой EMA.
  • EmaSlowLength: период медленной EMA.
  • RsiLength: период RSI.
  • RsiOverbought: уровень перекупленности RSI.
  • RsiOversold: уровень перепроданности RSI.
  • StopLossPerc: процент стоп-лосса.
  • TakeProfitPerc: процент тейк-профита.
  • StartHour: час начала сессии.
  • StartMinute: минута начала сессии.
  • EndHour: час окончания сессии.
  • EndMinute: минута окончания сессии.
  • CandleType: тип свечей.
