Stoch Supertrd ATR 200mA

Тэги:ЕМА

Эта стратегия сочетает в себе Supertrend, 200 EMA, Stochastic и индикатор остановки потери ATR. Для условий покупки, Stochastic должен быть ниже уровня 20, цена должна быть выше 200 Ema и Supertrend должен быть зеленым. Для условий продажи, это должно быть наоборот. Stochastic должен быть выше уровня 80, цена должна быть ниже 200 Ema и Supertrend должен быть красным.
