把极品做多做空指标红线上穿绿线改成选股公式

编写条件：

求把极品指标改成选股公式，要求红线上穿绿线为买点。 A:=EMA((CLOSE-REF(C,1))/REF(C,1)*10-(INDEXC-REF(INDEXC,1))/REF(INDEXC,1)*10,5),LINETHICK1,COLORRED; STICKLINE(A>0,0,A,1,2),COLORRED; STICKLINE(A<0,0,A,1,2),COLORGREEN; HSNP1:=CLOSE-REF(CLOSE,1); HSNP2:=IF(CLOSE-REF(CLOSE,1)>=0,HSNP1,0); HSNP3:=REF(CLOSE,1)-CLOSE; HSNP4:=IF(CLOSE-REF(CLOSE,1)<=0,HSNP3,0); HSNP5:=SUM(HSNP2,90)/SUM(HSNP4,90); HSNP6:=100-100/(1+HSNP5); HSNP7:=EMA(HSNP6,21); HSNP8:=EMA(HSNP7,5); HSNP:=EMA(HSNP7,3); NP:=(HSNP7-HSNP); NL:=(HSNP-HSNP7); STICKLINE(NL<0,0,NL,1,2),COLOR0B0B77,NODRAW; STICKLINE(NP<0,0,NP,1,2),COLOR666666,NODRAW; JJ :=(C*2+H+L)/4; SK := EMA(JJ,13) - EMA(JJ,21); SD := EMA(SK,3); SP := EMA(SK,10); 长线1:=IF(SD>=SP,SD,SP),LINETHICK1,COLORFFFFAA; 长线2:=IF(SP-SD,SP,SD),LINETHICK1,COLORWHITE; A1:=EMA(CLOSE,7)-EMA(CLOSE,21); B1:=EMA((0.668*REF(A1,1)+0.333*A1),1); 做多:IF(A1>=B1,A1,B1),LINETHICK1,COLORRED; 做空:IF(B1-A1,B1,A1),LINETHICK1,COLORGREEN; 买入差值:做多-做空; 卖出差值:做空-做多;

编写方法：

&nbsp;A1:=Ema(CLOSE,7)-EMA(CLOSE,21);
