Стратегия Donchian Stochastic
Стратегия основана на канале Дончиана и осцилляторе Стохастик. Вход происходит при пробое канала Дончиана, если Стохастик подтверждает перепроданность или перекупленность.
Тестирование показывает среднегодичную доходность около 85%. Стратегию лучше запускать на крипторынке.
Пробои за пределы канала подтверждаются импульсом Стохастика. Сделка открывается сразу, как только цена выходит из диапазона и осциллятор согласен.
Полезно для трейдеров, ожидающих быстрого продолжения движения. Стоп задаётся фиксированным процентом от цены входа.
Подробности
- Условия входа:
- Длинная:
Close > DonchianHigh && StochK > StochOverbought - Короткая:
Close < DonchianLow && StochK < StochOversold
- Длинная:
- Long/Short: Оба
- Условия выхода: неудача пробоя или противоположный сигнал
- Стопы: процентный уровень через
StopLossPercent - Параметры по умолчанию:
DonchianPeriod= 20StochPeriod= 14StochK= 3StochOverbought= 80StochOversold= 20CandleType= TimeSpan.FromMinutes(5).TimeFrame()StopLossPercent= 2 Пробой вверх канала предыдущих DonchianPeriod свечей подтверждается, когда %K выше StochOverbought, вниз — когда %K ниже StochOversold; обратное прочтение, перепроданный %K на пробое вверх, практически не встречается. %K — стохастик за StochPeriod свечей, сглаженный за StochK свечей, линия %D не участвует. Пробой считается неудачным и позиция закрывается, когда цена закрывается обратно за пробитым уровнем. Сигнал на вход против открытой позиции разворачивает её.
