calBBIDatas method

dynamic calBBIDatas(dynamic close, dynamic p1, dynamic p2, dynamic p3, dynamic p4,)

计算BBI指标 @param close:Array 收盘点 @param p1:int = 3 回溯周期 (1 <= p1 <= 300) @param p2:int = 6 回溯周期 (1 <= p2 <= 300) @param p3:int = 12 回溯周期 (1 <= p3 <= 300) @param p4:int = 24 回溯周期 (1 <= p4 <= 300) 最大的回溯周期之前的数值是-
