标题：请教

麻烦帮我编一个公式现实开盘价，在K线图上自动画个线，加上数字显示线的位置，谢谢

oo:=valuewhen(todaybar=1,open);

drawtext(todaybar=1,open+5*mindiff,numtostr(oo,2));

drawsl(todaybar=1,open,0,ref(todaybar,todaybar),3);

非常谢谢

还想麻烦下您，帮我把线和数字都改成黄色可以吗

oo:=valuewhen(todaybar=1,open);

drawtext(todaybar=1,open+5*mindiff,numtostr(oo,2)),coloryellow;

drawsl(todaybar=1,open,0,ref(todaybar,todaybar),3),coloryellow;
