请老师帮忙改一下　[文华财经]

 STEP1:=2/100;
MVALUE1:=2/10;
SARLINE:=SAR(4,STEP1,MVALUE1),CIRCLEDOT;
A:=VALUEWHEN(ISLASTBAR=1,SARLINE);
DRAWICON(SARLINE>0 AND REF(SARLINE,1)<0 , L, 'ICO10') ;
DRAWICON(SARLINE<0 AND REF(SARLINE,1)>0, H, 'ICO11') ;
能改成只在主图上标记最后一个图标。

即只在主图上显示出最后一个'ICO10'或'ICO11'。

STEP1:=2/100;
MVALUE1:=2/10;
SARLINE:=SAR(4,STEP1,MVALUE1),CIRCLEDOT;
A:=VALUEWHEN(ISLASTBAR=1,SARLINE);

N1:=BARSLAST(SARLINE>0 AND REF(SARLINE,1)<0)+1;
AA:=BACKSET(ISLASTBAR,N1);

N2:=BARSLAST(SARLINE<0 AND REF(SARLINE,1)>0)+1;
BB:=BACKSET(ISLASTBAR,N2);

DRAWICON(CROSS(AA,0.5), L, 'ICO10') ;
DRAWICON(CROSS(BB,0.5), H, 'ICO11') ;
