Стратегия Baseline2

Стратегия открывает лонг при касании поддержки, когда быстрая EMA выше медленной и RSI > 50. Шорт открывается при касании сопротивления, если быстрая EMA ниже медленной и RSI < 45. Объем должен превышать среднее значение, а ADX быть выше 15. Выход осуществляется по стопу и тейку, основанным на ATR.
