請高手把下面的通達信指標改寫成“牛”的選股公式 就是出現買入黃柱子的時候

VAR2:=(CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100;

VAR3:=SMA(SMA(VAR2,3,1),3,1)/28.57;

VAR4:=EMA(VAR3,5);

VAR5:=3*VAR3-2*VAR4;

牛:CROSS(VAR5,VAR3) AND VAR3<2.1 AND C>O;

（買入選股）

買入選股:CROSS((4*SMA((CLOSE-LLV(LOW,25))/(HHV(HIGH,25)-LLV(LOW,25))*100,5,1)-3*SMA(SMA((CLOSE-LLV(LOW,25))/(HHV(HIGH,25)-LLV(LOW,25))*100,5,1),3,1)),(8));

兩個不同
