【实战看盘工具——斜率观测器】飞狐源码

指标源码如下：

INPUT: 起点(50,1,9999,1),终点(2,0,9999,1);

            A1:=backset(barstatus=2,起点);

             {幅度:=(c-REF(c ,BARSLAST( CROSS(A1 ,0.5 )) ))/REF(c ,BARSLAST(
             CROSS(A1 ,0.5 )) )*100;}
             幅度:=(REF(c ,BARSLAST( CROSS(A2 ,0.5 )) )-REF(c ,BARSLAST( CROSS(A1
             ,0.5 )) ))/REF(c ,BARSLAST( CROSS(A1 ,0.5 )) )*100;
             斜率:=ATAN(幅度/((起点-终点) ))*180/3.1416;

             A5:=backset(barstatus=2,起点);
             A6:=backset(barstatus=2,终点);
             DRAWLINE(a5,C ,a6 AND  CROSS(A2 ,0.5 ) ,C,0),Color000fff,linethick2;
