calCRDatas method

dynamic calCRDatas(dynamic close, dynamic high, dynamic low, dynamic p0, dynamic p1, dynamic p2, dynamic p3,)

计算CR指标 @param close 收盘点 @param high 最高点 @param low 最低点 @param p0 CR的回溯周期 默认为26（5 <= p0 <= 500） @param p1 MA1的回溯周期 默认为5 （1 <= p1 <= 100） @param p2 MA2的回溯周期 默认为10 （1 <= p2 <= 100） @param p3 MA3的回溯周期 默认为20 （1 <= p3 <= 100）
