编写条件：

请老师帮忙写个出现买进提示的选股公式。先谢了。 成本:(MA(CLOSE,60)+MA(CLOSE,70)+MA(CLOSE,90)+MA(CLOSE,108))/4,COLORYELLOW,LINETHICK2; VAR1:=(C+H+O+L)/4; 卖出:XMA(VAR1,N)*(1+P1/1000),COLORGREEN,LINETHICK2; 买入:XMA(VAR1,M)*(1-P2/1000),COLORMAGENTA,LINETHICK2; 幅度:100*(卖出-买入)/买入,NODRAW; MA1:=MA(VAR1,3); STICKLINE(卖出>LOW AND 卖出MIN(C,O) AND 卖出LOW AND 卖出LOW AND 买入MIN(C,O) AND 买入LOW AND 买入HIGH,OPEN,CLOSE,3,0),COLORMAGENTA; STICKLINE(买入>HIGH,HIGH,LOW,0,0),COLORMAGENTA; DRAWTEXT(CROSS(C,买入) OR (L<买入),LOW*0.95,'Ｂ'),COLORRED,LINETHICK2; A3:=(C-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100; A4:=SMA(A3,3,1); A5:=SMA(A4,3,1); A6:=3*A4-2*A5; A7:=C-REF(C,1); A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6); 买:=LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2)); DRAWTEXT(FILTER(买=1,5),LOW-0.05,'↖买进'),COLORYELLOW; STICKLINE(买,OPEN,CLOSE,2,0),COLORYELLOW; VAR11:=(2*CLOSE+HIGH+LOW+OPEN)/5; A11: (EMA(VAR11,3)+EMA(VAR11,6)+EMA(VAR11,12)+EMA(VAR11,24))/4; A22: EMA(A11,2); A33: EMA(A22,2); A44: EMA(A33,2); A55: EMA(A44,2); A66: EMA(A55,2); A77: EMA(A66,2); A88: EMA(VAR11,2.78)*1.028; A99: MA(OPEN,3.2)*1.028;

编写方法：

&nbsp;A7:=C-REF(C,1);

A8:=100*Ema(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);

买:=LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND crOSS(A8,MA(A8,2));

FILTER(买=1,5);
