请老师帮忙编写下博易大师开盘价线（以夜盘九点开盘到下午三点收盘为一天）

NS:=IF(TIME>=180000,1,REF(NS,1));TOTALVOL:=IF((TIME>=180000 AND REF(TIME,1)<180000) OR (NS=0 AND DATE<>REF(DATE,1)),V,REF(TOTALVOL,1)+V);TOTALAMOUNT:=IF((TIME>=180000 AND REF(TIME,1)<180000) OR (NS=0 AND DATE<>REF(DATE,1)),(O+H+L+C)/4*V,REF(TOTALAMOUNT,1)+(O+H+L+C)/4*V);夜盘均价线:=TOTALAMOUNT/TOTALVOL,PRECIS0,COLORWHITE;分:=IF(DATE<>REF(DATE,1),0,REF(分,1))+V;时:=IF(DATE<>REF(DATE,1),0,REF(时,1))+(C+O+H+L)*0.25*V;日盘均价:=时/分;均线:IF(ISCONTRACT('L') OR ISCONTRACT('PP') OR ISCONTRACT('JD') OR ISCONTRACT('TF') OR ISCONTRACT('T') OR ISCONTRACT('IF') OR ISCONTRACT('CS')OR ISCONTRACT('IH') OR ISCONTRACT('RBTN') OR ISCONTRACT('C') OR ISCONTRACT('LMNDE') OR ISCONTRACT('LMNDE'),日盘均价,夜盘均价线),PRECIS0,CIRCLEDOT;
