N:=IF(PERIOD=1,30,IF(PERIOD=2,10,IF(PERIOD=3,6,IF(PERIOD=4,3,IF(PERIOD=5,2,IF(PERIOD=6,1,NULL))))));
HH:=VALUEWHEN(DAYBARPOS=N,HHV(H,DAYBARPOS));
LL:=VALUEWHEN(DAYBARPOS=N,LLV(L,DAYBARPOS));
IF(DAYBARPOS>=1&&DAYBARPOS<N,NULL,HH),COLORRED,DOT;
IF(DAYBARPOS>=1&&DAYBARPOS<N,NULL,LL),COLORGREEN,DOT;
DRAWNUMBER(REFX(DAYBARPOS=1,1)||ISLASTBAR,HH,HH,2,COLORRED);
能否修改成只显示三天以内的高低点（最好能给一个可调参数1-3天内），谢谢

修改参数M，参考：
M:=3;
Q:=BACKSET(ISLASTBAR,SUMBARS(DAYBARPOS=1,M));
N:=IF(PERIOD=1,30,IF(PERIOD=2,10,IF(PERIOD=3,6,IF(PERIOD=4,3,IF(PERIOD=5,2,IF(PERIOD=6,1,NULL))))));
HH:=VALUEWHEN(DAYBARPOS=N,HHV(H,DAYBARPOS));
LL:=VALUEWHEN(DAYBARPOS=N,LLV(L,DAYBARPOS));
IF(DAYBARPOS>=1&&DAYBARPOS<N||NOT(Q),NULL,HH),COLORRED,DOT;
IF(DAYBARPOS>=1&&DAYBARPOS<N||NOT(Q),NULL,LL),COLORGREEN,DOT;
DRAWNUMBER(REFX(DAYBARPOS=1,1)&&Q||ISLASTBAR,HH,HH,2,COLORRED);
DRAWNUMBER(REFX(DAYBARPOS=1,1)&&Q||ISLASTBAR,LL,LL,2,COLORGREEN);
