帮忙改个同花顺“出现底买入”选股公式,绿色箭头所指之处，也就是“底买入”等于60时选出，类似买入信号。
再帮看一下这个信号出现时会不会飘移，谢谢了！
V8:=600*(EMA(C,3)-EMA(L,30))/EMA(L,30);
V9:=EMA(V8,7);
VA:=(WINNER(120*C/100)-WINNER(100*C/100))*100;
VB:=(-100)*(WINNER(120*C/100)-WINNER(100*C/100))+5;
底买入: IF(VA+VB< 7 AND CROSS(V8,V9) AND V9< -18 AND V9< VB,60,50);
VC:=(2*C+H+L)/4;
VD:=LLV(L,34);
VE:=HHV(H,34);
VF:=LLV(L,21);
V10:=HHV(H,21);
V11:=EMA((VC-VF)/(V10-VD)*100,5);
V12:=EMA((VC-VD)/(VE-VD)*100,8);

顶区:V12;
