有什么方法可以自动画这些线
P:=MA(C,10);
当现价大于P时自动画出下面这些线
BUY:p+0.25,circledot;
BF:P+0.50,circledot;
Bu:p+0.70,circledot;
Bi:p+0.9,circledot;
Byt:=p+1.15,circledot;
Byg:=p+1.4,circledot;
Bye:=p+1.8,circledot;
当现价小于P时自动画出下面这些线,上面的线隐藏起来.
SELL:=p-0.25,circledot;
CF:=P-0.50,circledot;
cu:=p-0.70,circledot;
ci:=p-0.9,circledot;
cyt:=p-1.15,circledot;
cyg:=p-1.4,circledot;
cye:=p-1.8,circledot;
要怎么写才能表达出来.谢谢.
