黄色区域出现‘S’为选股条件，只需以下函数即可：

v0:=VOL*(O C H L)/4;

A:=EMA(v0,21)/EMA(VOL,21);

SY:=A=ref(A,1);

var1:=CLOSEREF(CLOSE,1) AND CLOSEREF(CLOSE,2);

Var2:=REF(Var1,1) AND CLOSE=REF(CLOSE,2);

Var3:=REF(Var2,1) AND CLOSE=REF(CLOSE,1) AND CLOSE=REF(CLOSE,2);

Var5:=REF(Var4,1) AND CLOSE=REF(CLOSE,1) AND CLOSE=REF(CLOSE,2);

Var7:=REF(Var6,1) AND CLOSE=REF(CLOSE,1) AND CLOSE=REF(CLOSE,2);

Var9:=REF(Var8,1) AND CLOSE=REF(CLOSE,1) AND CLOSE=REF(CLOSE,2);

VarB:=REF(VarA,1) AND CLOSE=REF(CLOSE,1) AND CLOSE=REF(CLOSE,2);

VarD:=CLOSEVar1A:=(REF(Var1 OR Var2 OR Var3 OR Var4 OR Var5 OR Var6 OR Var7 OR

Var8 OR Var9 OR VarA OR VarB OR VarC,1) AND VarD AND SY);

MR:IF(Var1A,50,0);

希望是您要的，并祝您股市好运。
