公式模块：

A:=MA(-100*(HHV(HIGH,34)-CLOSE)/(HHV(HIGH,34)-LLV(LOW,34)),19);

B:=-100*(HHV(HIGH,14)-CLOSE)/(HHV(HIGH,14)-LLV(LOW,14)); D:=EMA(-100*(HHV(HIGH,34)-CLOSE)/(HHV(HIGH,34)-LLV(LOW,34)),4); 长期线:=A+100; 短期线:=B+100; 中期线:=D+100; 低位金叉:50*(长期线<15 AND REF(长期线,1)<15 AND 中期线<18 AND 短期线>REF(短期线,1) AND crOSS(短期线,长期线) AND 短期线>中期线 AND (REF(短期线,1)<5 OR REF(短期线,2)<5 ) AND (中期线>=长期线 OR REF( 短期线,1)<1 ));
