例二、找出笑脸和买入信号
以《跟庄建仓》为例。
A01:=DYNAINFO(7);
A03:=BARSCOUNT(CLOSE);
A04:=(SMA((CLOSE / HHV(HIGH,120)),3,1) * 100);
A05:=IF((A03 > 20),A04,0);
A06:=IF((LOW > A01),0,IF((HIGH < A01),1,(((A01 - LOW) + 0.009) / ((HIGH - LOW) + 0.009))));
A07:=DMA(A06,(VOL / CAPITAL)) * 60;
A09:=IF((((A07 > 0) AND (A07 > REF(A07,1))) AND (A05 <= 88)),A07,0);
Var1:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
Var2:=EMA(Var1,8);
Var3:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA(SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1),3,1);
趋势:=EMA(Var3,3)-10;
FILLRGN(趋势>80,趋势,80);
DRAWICON(CROSS(趋势,0),0,1);
FILLRGN((A09 > 0 AND (趋势<20 OR 趋势>REF(趋势,1)AND 趋势<50)),0,A09),colorFFFF00;
机构建仓区:0,LINETHICK0,colorFFFF00;
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100;
STICKLINE(趋势<=13,0,20,5,0),colorcc9900;
DRAWTEXT(FILTER(趋势<=13,15),30,'准备现金'),colorcc9900;
STICKLINE(趋势<=13 AND Var4>13,0,50,5,0),color0099ff;
Var5:=FILTER((趋势<=13 AND Var4>13),10);
DRAWTEXT(Var5,60,'买入'),color0099ff;
STICKLINE(趋势>=90 AND Var4,0,30,5,0),colorgray;
Var6:=FILTER(趋势>=90,10);
DRAWTEXT(Var6,40,'清仓'),colorgray;
Var7:=LLV(LOW,30);
Var8:=HHV(HIGH,30);
Var9:=EMA((CLOSE-Var7)/(Var8-Var7)*4,4)*25;
STICKLINE(Var9>90,100,105,10,2),COLORRED;
STICKLINE(CROSS(Var4,-40),10,55,6,0),COLORRED;
Var10:=(Var9-LLV(Var9,4))/(HHV(Var9,4)-LLV(Var9,4))*100;
DRAWTEXT(IF(CROSS(Var9,Var10) AND Var9>87,95,0),88,'险'),Color00FF00,ALIGN1;
DRAWICON(CROSS(90,Var9),95,9);
Var11:=SMA(ABS(L-REF(L,1)),3,1)/SMA(MAX(L-REF(L,1),0),3,1)*100;
Var12:=HHV(Var11,30)*8;
火焰山:EMA(IF(LOW<=Var7 AND 趋势<40,(Var11+Var12),0),3)/618,COLORRED,linethick2;
STICKLINE(火焰山>0,0 ,火焰山*1.2,8,0 ),COLORRED;
Var13:=(MA(C,1)+MA(C,3)+MA(C,5)+MA(C,7)+MA(C,9))/5;
Var14:=(MA(C,2)+MA(C,4)+MA(C,6)+MA(C,8)+MA(C,10))/5;
趋势线: 趋势,colorff0000;
Var16:=MAX(EMA(Var13,2)-EMA(Var14,5),0)*200;
Var17:=EMA(Var16,5);
波浪峰:Var17,stick,colorff00ff;
STICKLINE(Var17<REF(Var17,1),0,Var17,1,0),color00ff00;
Var18:=MA(趋势线,8);
if(CROSS(Var2,Var18) AND Var2<15,50,0),COLORRED;
DRAWTEXT(CROSS(趋势线,Var2)AND 趋势线>REF(趋势线,1)AND 趋势线<50,50,'追涨'),COLORFF0000;
分析：这个公式输出语句非常多,但多数都是用于趋势判断的。所以不用管它。仍按我们既定的思路进行。
第一步｛从后往前找｝,先删除发出信号关键语句之后的（红色为输出语句,它以下的语句已经删去,蓝色为等待下步删除的）
A01:=DYNAINFO(7);
A03:=BARSCOUNT(CLOSE);
A04:=(SMA((CLOSE / HHV(HIGH,120)),3,1) * 100);
A05:=IF((A03 > 20),A04,0);
A06:=IF((LOW > A01),0,IF((HIGH < A01),1,(((A01 - LOW) + 0.009) / ((HIGH - LOW) + 0.009))));
A07:=DMA(A06,(VOL / CAPITAL)) * 60;
A09:=IF((((A07 > 0) AND (A07 > REF(A07,1))) AND (A05 <= 88)),A07,0);
Var1:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
Var2:=EMA(Var1,8);
Var3:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA(SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1),3,1);
趋势:=EMA(Var3,3)-10;
FILLRGN(趋势>80,趋势,80);
DRAWICON(CROSS(趋势,0),0,1);
FILLRGN((A09 > 0 AND (趋势<20 OR 趋势>REF(趋势,1)AND 趋势<50)),0,A09),colorFFFF00;
机构建仓区:0,LINETHICK0,colorFFFF00;
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100;
STICKLINE(趋势<=13,0,20,5,0),colorcc9900;
DRAWTEXT(FILTER(趋势<=13,15),30,'准备现金'),colorcc9900;
STICKLINE(趋势<=13 AND Var4>13,0,50,5,0),color0099ff;
Var5:=FILTER((趋势<=13 AND Var4>13),10);
DRAWTEXT(Var5,60,'买入'),color0099ff;
第二步｛删除没用条｝后
Var3:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA(SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1),3,1);
趋势:=EMA(Var3,3)-10;
DRAWICON(CROSS(趋势,0),0,1);
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100;
Var5:=FILTER((趋势<=13 AND Var4>13),10);
DRAWTEXT(Var5,60,'买入'),color0099ff;
第三步｛去掉修饰符后｝：
趋势:=EMA(Var3,3)-10;
CROSS(趋势,0);
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100;
Var5:=FILTER((趋势<=13 AND Var4>13),10);
Var5;
第四步｛个别加等号｝本公式中的“条件”语句都是不输出的,所以此项省略,但因是要笑脸和买入两个信号,所以还必须把它们连结起来：
Var3:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA(SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1),3,1);
趋势:=EMA(Var3,3)-10;
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100;
Var5:=FILTER((趋势<=13 AND Var4>13),10);
CROSS(趋势,0)or Var5;
