主题：老师们好：请帮我编一个开盘价公式，谢谢！

variable:o1=0,o2=0,o3=0;
if time=090100 then o1:=o;
if time=103100 then o2:=o;
if time =133100 then o3:=o;

drawline(time=090100,o1,time=090200,o1,0,colorred);
drawline(time=090200,o1,time=090300,o1,0,colorred);
drawline(time=090300,o1,time=090400,o1,0,colorred);
drawline(time=090400,o1,time=090500,o1,0,colorred);
drawline(time=090500,o1,time=090600,o1,0,colorred);

.........

drawline(time=145900,o1,time=150000,o1,0,colorred);
