TN := BARSLAST(DATE <> REF(DATE, 1)) + 1;

HHQ:=HHV(H,NNQ);//N日HIGH的最高价

LC:=LLV(C,NNQ);//N日CLOSE的最低价

HC:=HHV(C,NNQ);//N日CLOSE的最高价

LLQ:=LLV(L,NNQ);//N日LOW的最低价

RANGEX:=MAX(HHQ-LC,HC-LLQ);//计算震荡区间RANGE

TODAYOPEN := VALUEWHEN(TN = 1, OPEN); //今日开盘价

BUYLINE:IF(TJ&&PERIOD<7,TODAYOPEN +K1*RANGEX,NULL),COLORGREEN,LINETHICK1;//上轨

SELLLINE:IF(TJ&&PERIOD<7,TODAYOPEN -K2*RANGEX,NULL),COLORRED,LINETHICK1;//下轨

参考：

A:=BACKSET(ISLASTBAR,DAYBARPOS);

B:=IF(PERIOD=8,NULL,VALUEWHEN(DAYBARPOS=1,O)),COLORMAGENTA,LINETHICK1;

开盘价:IF(A,B,NULL),COLORMAGENTA,LINETHICK1;
