bs点选股公式

买线:=EMA(C,2);

卖线:=EMA(SLOPE(C,21)*20+C,42);

X:CROSS(买线,卖线);

朋友，以下是你要的选股公式：
N:=20;
M:=32;
P1:=80;
P2:=100;
VARR:=(C+H+O+L)/4;
卖出:=XMA(VARR,N)*(1+P1/1000),COLORLIBLUE,LINETHICK2;
买入:=XMA(VARR,M)*(1-P2/1000),COLORMAGENTA,LINETHICK2;
幅度:=100*(卖出-买入)/买入;
MA1:=MA(VARR,3);
ZHOUMIN:CROSS(C,买入) OR (L<买入);

var1:=CLOSE>REF(CLOSE,1) AND CLOSE>REF(CLOSE,2);
VarD:=CLOSE<REF(CLOSE,1) AND CLOSE<REF(CLOSE,2);
VarE:=REF(VarD,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
VarF:=REF(VarE,1) AND CLOSE<=REF(CLOSE,1) AND CLOSE>=REF(CLOSE,2);
Var10:=REF(VarF,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
Var11:=REF(Var10,1) AND CLOSE<=REF(CLOSE,1) AND CLOSE>=REF(CLOSE,2);
Var12:=REF(Var11,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
Var13:=REF(Var12,1) AND CLOSE<=REF(CLOSE,1) AND CLOSE>=REF(CLOSE,2);
Var14:=REF(Var13,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
Var15:=REF(Var14,1) AND CLOSE<=REF(CLOSE,1) AND CLOSE>=REF(CLOSE,2);
Var16:=REF(Var15,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
Var17:=REF(Var16,1) AND CLOSE<=REF(CLOSE,1) AND CLOSE>=REF(CLOSE,2);
Var18:=REF(Var17,1) AND CLOSE>=REF(CLOSE,1) AND CLOSE<=REF(CLOSE,2);
REF(VarD OR VarE OR VarF OR Var10 OR Var11 OR Var12 OR Var13 OR Var14 OR Var15 OR Var16 OR Var17 OR Var18,1) AND Var1;

{未来函数，慎用！}
XG:(ZIG(3,5)>REF(ZIG(3,5),1)) AND (REF(ZIG(3,5),1)<=REF(ZIG(3,5),2))
AND (REF(ZIG(3,5),2)<=REF(ZIG(3,5),3));
