把高低撑压主图指标改为大智慧的

编写要求：

N1:=100; KD:=BARSLAST(CURRBARSCOUNT=N1); GD:=CONST(IF(ISLASTBAR=1,HHV(H,KD),0)); DD:=CONST(IF(ISLASTBAR=1,LLV(L,KD),0)); 高区:IF(CURRBARSCOUNT<=N1,GD,DRAWNULL),COLORWHITE; 低区:IF(CURRBARSCOUNT<=N1,DD,DRAWNULL),COLORWHITE;

解答：

?n:=100;

aa:=BARSLAST(cross(BACKSET( DISPSTATUS=2,n),0.5));
