简单一句话公式源码：
C>REF(C,1) AND C>O AND LONGCROSS(C,MA(C,20),1)=1 AND LONGCROSS(C,MA(C,30),1)=1;
{真金不怕火炼}
VAR1:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;
VAR2:=SMA(VAR1,3,1);
VAR3:=SMA(VAR2,3,1);
VAR4:=3*VAR2-2*VAR3;
VAR5:=CROSS(VAR4,VAR2) AND VAR2<20;
VAR6:=CROSS(VAR2,VAR4) AND VAR2>80;
DRAWICON(VAR5,LOW*0.98,1);
DRAWICON(VAR6,HIGH*1.02,2);
