                         DRAWLINE(HIGH>=HHV(HIGH,M),HIGH,LOW<=LLV(LOW,M),LOW,COLORRED);
                         DRAWLINE(LOW<=LLV(LOW,M),LOW,HIGH>=HHV(HIGH,M),HIGH,COLORGREEN);

                        2 计算高 低 点之间的K线数值，并标识在低点下方或高点上方。（如图）
     
                         谢谢

参考：

M:=20;
  
DRAWLINE1(CROSS(BACKSET(LOW<=LLV(LOW,M),BARSLAST(HIGH>=HHV(HIGH,M))+1),0.5),HIGH,CROSS(BACKSET(HIGH>=HHV(HIGH,M),BARSLAST(LOW<=LLV(LOW,M))+1),0.5),LOW,0);
DRAWLINE1(CROSS(BACKSET(HIGH>=HHV(HIGH,M),BARSLAST(LOW<=LLV(LOW,M))+1),0.5),LOW,CROSS(BACKSET(LOW<=LLV(LOW,M),BARSLAST(HIGH>=HHV(HIGH,M))+1),0.5),HIGH,0);

DRAWNUMBER(CROSS(BACKSET(LOW<=LLV(LOW,M),BARSLAST(HIGH>=HHV(HIGH,M))+1),0.5),H,BARSLAST(CROSS(BACKSET(HIGH>=HHV(HIGH,M),BARSLAST(LOW<=LLV(LOW,M))+1),0.5)),0,COLORYELLOW);
DRAWNUMBER(CROSS(BACKSET(HIGH>=HHV(HIGH,M),BARSLAST(LOW<=LLV(LOW,M))+1),0.5),L,BARSLAST(CROSS(BACKSET(LOW<=LLV(LOW,M),BARSLAST(HIGH>=HHV(HIGH,M))+1),0.5)),0,COLORYELLOW);

 谢谢老师，非常好。
 还有一个问题，最近12日的低点为起点，每根K线最低价下面标识顺序数字，一直到最新的K线。如图
