第七讲：从源码中提取选股公式

　　口诀：从后往前找，删除没用条，去掉修饰符，个别加等号。
例一：找出买点
VAR1:=(((HHV(HIGH,36) - CLOSE) / (HHV(HIGH,36) - LLV(LOW,36))) * 100){XG51};
VAR2:=SMA(VAR1,5,1){XG51};
VAR3:=Sma(VAR2,8,1){XG51};
H1:ema(CLOSE,8),LINETHICK1{XG51};
H2:EMA(H1,20),LINETHICK1{XG51};
VAR4:=(crOSS(VAR2,VAR3) AND (VAR3 < 20)){XG51};
VAR5:=((CLOSE > (LLV(CLOSE,60) + (0.3 * LLV(CLOSE,60)))) AND VAR4){XG51};
VAR6:=IF((CLOSE > 1000),VAR4,VAR5){XG51};
M1:EMA(CLOSE,60){XG51};
M2:EMA(CLOSE,89){XG51};
M3:EMA(CLOSE,233),LINETHICK1{XG51};
M4:EMA(CLOSE,583),LINETHICK1{XG51};
stICKLINE((H1 > H2),H1,H2,1,0.8){XG51};
STICKLINE((H1 < H2),H1,H2,1,0.8){XG51};
DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'买'){XG51};
DRAWTEXT(VAR6,(HIGH * 1.08),'卖');

分解说明：
VAR1:=(((HHV(HIGH,36) - CLOSE) / (HHV(HIGH,36) - LLV(LOW,36))) * 100){XG51};
VAR2:=SMA(VAR1,5,1){XG51};
VAR3:=SMA(VAR2,8,1){XG51};
H1:EMA(CLOSE,8),LINETHICK1{XG51};
H2:EMA(H1,20),LINETHICK1{XG51};
VAR4:=(CROSS(VAR2,VAR3) AND (VAR3 < 20)){XG51};
VAR5:=((CLOSE > (LLV(CLOSE,60) + (0.3 * LLV(CLOSE,60)))) AND VAR4){XG51};
VAR6:=IF((CLOSE > 1000),VAR4,VAR5){XG51};
M1:EMA(CLOSE,60){XG51};
M2:EMA(CLOSE,89){XG51};
M3:EMA(CLOSE,233),LINETHICK1{XG51};
M4:EMA(CLOSE,583),LINETHICK1{XG51};
STICKLINE((H1 > H2),H1,H2,1,0.8){XG51};
STICKLINE((H1 < H2),H1,H2,1,0.8){XG51};
第一步｛从后往前找｝找到下面这行&ldquo;买&rdquo;的输出语句。然后看这条语句的基本条件。
DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'买'){XG51};
查看结果：输出文字　　交叉　条件，条件　　　直 接 输 出 语 句　　　　　输出位置　　文字
DRAWTEXT(VAR6,(HIGH * 1.08),'卖'){XG51};
知道&ldquo;基本条件&rdquo;为　H1,H2，那么与此没有任何关系的语句从后往前删除。删的办法有两种：一是直接删掉；二是先用｛｝括上，待没问题时再一次性删除。加蓝色的为找到的不输出语句。
第二步｛删除没用条｝后，剩下的有用语句：
H1:EMA(CLOSE,8),LINETHICK1;　｛加蓝的为修饰类函数，原则一律删除。｝
H2:EMA(H1,20),LINETHICK1{XG51};
DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'买'){XG51};
第三步｛去掉修饰符｝　分别去掉：指标线粗细、显示文字、文字位置函数和文字
H1:EMA(CLOSE,8){XG51};
H2:EMA(H1,20){XG51};
CROSS(H1,H2) AND CLOSE < EMA(CLOSE,60){XG51};
第四步｛个别加等号｝　条件选股只能输出一条语句，上面这三行为全部输出，所以，作为&ldquo;条件&rdquo;的前两行还必须在冒号后面加上等号，表达不输出。结果：
H1:=EMA(CLOSE,8){XG51};
H2:=EMA(H1,20){XG51};
CROSS(H1,H2) AND CLOSE < EMA(CLOSE,60){XG51};
例二、找出笑脸和买入信号
以本人发过的《跟庄建仓》为例。
A01:=DYNAINFO(7){XG51};
A03:=BARSCOUNT(CLOSE){XG51};
A04:=(SMA((CLOSE / HHV(HIGH,120)),3,1) * 100){XG51};
A05:=IF((A03 > 20),A04,0){XG51};
A06:=IF((LOW > A01),0,IF((HIGH < A01),1,(((A01 - LOW) + 0.009) / ((HIGH - LOW) + 0.009)))){XG51};
A07:=dma(A06,(vol / CAPITAL)) * 60{XG51};
A09:=IF((((A07 > 0) AND (A07 > REF(A07,1))) AND (A05 <= 88)),A07,0){XG51};
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){XG51};
Var2:=EMA(Var1,8){XG51};
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){XG51};
趋势:=EMA(Var3,3)-10{XG51};
FILLRGN(趋势>80,趋势,80){XG51};
DRAWICON(CROSS(趋势,0),0,1){XG51};
FILLRGN((A09 > 0 AND (趋势<20 OR 趋势>REF(趋势,1)AND 趋势<50)),0,A09),colorFFFF00{XG51};
机构建仓区:0,LINETHICK0,colorFFFF00{XG51};
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100{XG51};
STICKLINE(趋势<=13,0,20,5,0),colorcc9900{XG51};
DRAWTEXT(FILTER(趋势<=13,15),30,'准备现金'),colorcc9900{XG51};
STICKLINE(趋势<=13 AND Var4>13,0,50,5,0),color0099ff{XG51};
Var5:=FILTER((趋势<=13 AND Var4>13),10){XG51};
DRAWTEXT(Var5,60,'买入'),color0099ff{XG51};
STICKLINE(趋势>=90 AND Var4,0,30,5,0),colorgray{XG51};
Var6:=FILTER(趋势>=90,10){XG51};
DRAWTEXT(Var6,40,'清仓'),colorgray{XG51};
Var7:=LLV(LOW,30){XG51};
Var8:=HHV(HIGH,30){XG51};
Var9:=EMA((CLOSE-Var7)/(Var8-Var7)*4,4)*25{XG51};
STICKLINE(Var9>90,100,105,10,2),COLORWHITE{XG51};
STICKLINE(CROSS(Var4,-40),10,55,6,0),COLORWHITE{XG51};
Var10:=(Var9-LLV(Var9,4))/(HHV(Var9,4)-LLV(Var9,4))*100{XG51};
DRAWTEXT(IF(CROSS(Var9,Var10) AND Var9>87,95,0),88,'险'),Color00FF00,ALIGN1{XG51};
DRAWICON(CROSS(90,Var9),95,9){XG51};
Var11:=SMA(Abs(L-REF(L,1)),3,1)/SMA(MAX(L-REF(L,1),0),3,1)*100{XG51};
Var12:=HHV(Var11,30)*8{XG51};
火焰山:EMA(IF(LOW<=Var7 AND 趋势<40,(Var11+Var12),0),3)/618,COLORWHITE,linethick2{XG51};
STICKLINE(火焰山>0,0 ,火焰山*1.2,8,0 ),COLORWHITE{XG51};
Var13:=(MA(C,1)+MA(C,3)+MA(C,5)+MA(C,7)+MA(C,9))/5{XG51};
Var14:=(MA(C,2)+MA(C,4)+MA(C,6)+MA(C,8)+MA(C,10))/5{XG51};
趋势线: 趋势,colorff0000{XG51};
Var16:=MAX(EMA(Var13,2)-EMA(Var14,5),0)*200{XG51};
Var17:=EMA(Var16,5){XG51};
波浪峰:Var17,stick,colorff00ff{XG51};
STICKLINE(Var17<REF(Var17,1),0,Var17,1,0),color00ff00{XG51};
Var18:=MA(趋势线,8){XG51};
if(CROSS(Var2,Var18) AND Var2<15,50,0),COLORWHITE{XG51};
DRAWTEXT(CROSS(趋势线,Var2)AND 趋势线>REF(趋势线,1)AND 趋势线<50,50,'追涨'),COLORFF0000{XG51};
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){XG51};
A03:=BARSCOUNT(CLOSE){XG51};
A04:=(SMA((CLOSE / HHV(HIGH,120)),3,1) * 100){XG51};
A05:=IF((A03 > 20),A04,0){XG51};
A06:=IF((LOW > A01),0,IF((HIGH < A01),1,(((A01 - LOW) + 0.009) / ((HIGH - LOW) + 0.009)))){XG51};
A07:=DMA(A06,(VOL / CAPITAL)) * 60{XG51};
A09:=IF((((A07 > 0) AND (A07 > REF(A07,1))) AND (A05 <= 88)),A07,0){XG51};
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){XG51};
Var2:=EMA(Var1,8){XG51};
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){XG51};
趋势:=EMA(Var3,3)-10{XG51};
FILLRGN(趋势>80,趋势,80){XG51};
DRAWICON(CROSS(趋势,0),0,1){XG51};
FILLRGN((A09 > 0 AND (趋势<20 OR 趋势>REF(趋势,1)AND 趋势<50)),0,A09),colorFFFF00{XG51};
机构建仓区:0,LINETHICK0,colorFFFF00{XG51};
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100{XG51};
STICKLINE(趋势<=13,0,20,5,0),colorcc9900{XG51};
DRAWTEXT(FILTER(趋势<=13,15),30,'准备现金'),colorcc9900{XG51};
STICKLINE(趋势<=13 AND Var4>13,0,50,5,0),color0099ff{XG51};
Var5:=FILTER((趋势<=13 AND Var4>13),10){XG51};
DRAWTEXT(Var5,60,'买入'),color0099ff{XG51};
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){XG51};
趋势:=EMA(Var3,3)-10{XG51};
DRAWICON(CROSS(趋势,0),0,1){XG51};
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100{XG51};
Var5:=FILTER((趋势<=13 AND Var4>13),10){XG51};
DRAWTEXT(Var5,60,'买入'),color0099ff{XG51};
第三步｛去掉修饰符后｝：
趋势:=EMA(Var3,3)-10{XG51};
CROSS(趋势,0){XG51};
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100{XG51};
Var5:=FILTER((趋势<=13 AND Var4>13),10){XG51};
Var5{XG51};
第四步｛个别加等号｝本公式中的&ldquo;条件&rdquo;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){XG51};
趋势:=EMA(Var3,3)-10{XG51};
Var4:=(趋势-REF(趋势,1))/REF(趋势,1)*100{XG51};
Var5:=FILTER((趋势<=13 AND Var4>13),10){XG51};
CROSS(趋势,0)or Var5;&nbsp{X?G?5?1?C?N?{};
