常用函數(shù)、指標——第七講從源碼中提取選股公式­

­

　　要點：從后往前找，刪除沒用條，去掉修飾符，個別加等號。­

­

例一：找出買點­

VAR1:=(((HHV(HIGH,36) - CLOSE) / (HHV(HIGH,36) - LLV(LOW,36))) * 100);­

VAR2:=SMA(VAR1,5,1);­

VAR3:=SMA(VAR2,8,1);­

H1:EMA(CLOSE,8),LINETHICK1;­

H2:EMA(H1,20),LINETHICK1;­

VAR4:=(CROSS(VAR2,VAR3) AND (VAR3 < 20));­

VAR5:=((CLOSE > (LLV(CLOSE,60) + (0.3 * LLV(CLOSE,60)))) AND VAR4);­

VAR6:=IF((CLOSE > 1000),VAR4,VAR5);­

M1:EMA(CLOSE,60);­

M2:EMA(CLOSE,89);­

M3:EMA(CLOSE,233),LINETHICK1;­

M4:EMA(CLOSE,583),LINETHICK1;­

STICKLINE((H1 > H2),H1,H2,1,0.8);­

STICKLINE((H1 < H2),H1,H2,1,0.8);­

DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'買');­

DRAWTEXT(VAR6,(HIGH * 1.08),'賣');­

­

­

分解說明：­

­

VAR1:=(((HHV(HIGH,36) - CLOSE) / (HHV(HIGH,36) - LLV(LOW,36))) * 100);­

VAR2:=SMA(VAR1,5,1);­

VAR3:=SMA(VAR2,8,1);­

H1:EMA(CLOSE,8),LINETHICK1;­

H2:EMA(H1,20),LINETHICK1;­

VAR4:=(CROSS(VAR2,VAR3) AND (VAR3 < 20));­

VAR5:=((CLOSE > (LLV(CLOSE,60) + (0.3 * LLV(CLOSE,60)))) AND VAR4);­

VAR6:=IF((CLOSE > 1000),VAR4,VAR5);­

M1:EMA(CLOSE,60);­

M2:EMA(CLOSE,89);­

M3:EMA(CLOSE,233),LINETHICK1;­

M4:EMA(CLOSE,583),LINETHICK1;­

STICKLINE((H1 > H2),H1,H2,1,0.8);­

STICKLINE((H1 < H2),H1,H2,1,0.8);­

第一步｛從后往前找｝找到下面這行“買”的輸出語句。然后看這條語句的基本條件。­

　　　　　DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'買');­

查看結果：輸出文字　　交叉　條件，條件　　　直接輸出語句　　　　　輸出位置　　文字­

DRAWTEXT(VAR6,(HIGH * 1.08),'賣');­

知道“基本條件”為　H1,H2，那么與此沒有任何關系的語句從后往前刪除。刪的辦法有兩種：一是直接刪掉；二是先用｛｝括上，待沒問題時再一次性刪除。加藍色的為找到的不輸出語句。­

­

第二步｛刪除沒用條｝后，剩下的有用語句：­

H1:EMA(CLOSE,8),LINETHICK1;　｛加藍的為修飾類函數(shù)，原則一律刪除。｝­

H2:EMA(H1,20),LINETHICK1;­

DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'買');­

­

第三步｛去掉修飾符｝　分別去掉：指標線粗細、顯示文字、文字位置函數(shù)和文字­

H1:EMA(CLOSE,8);­

H2:EMA(H1,20);­

CROSS(H1,H2) AND CLOSE < EMA(CLOSE,60);­

­

第四步｛個別加等號｝　條件選股只能輸出一條語句，上面這三行為全部輸出，所以，作為“條件”的前兩行還必須在冒號后面加上等號，表達不輸出。結果：­

H1:=EMA(CLOSE,8);­

H2:=EMA(H1,20);­

CROSS(H1,H2) AND CLOSE < EMA(CLOSE,60);­

­

例二、找出笑臉和買入信號­

以本人發(fā)過的《跟莊建倉》為例。­

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);­

趨勢:=EMA(Var3,3)-10;­

FILLRGN(趨勢>80,趨勢,80);­

DRAWICON(CROSS(趨勢,0),0,1);­

FILLRGN((A09 > 0 AND (趨勢<20 OR 趨勢>REF(趨勢,1)AND 趨勢<50)),0,A09),colorFFFF00;­

機構建倉區(qū):0,LINETHICK0,colorFFFF00;­

­

Var4:=(趨勢-REF(趨勢,1))/REF(趨勢,1)*100;­

STICKLINE(趨勢<=13,0,20,5,0),colorcc9900;­

DRAWTEXT(FILTER(趨勢<=13,15),30,'準備現(xiàn)金'),colorcc9900;­

STICKLINE(趨勢<=13 AND Var4>13,0,50,5,0),color0099ff;­

Var5:=FILTER((趨勢<=13 AND Var4>13),10);­

DRAWTEXT(Var5,60,'買入'),color0099ff;­

STICKLINE(趨勢>=90 AND Var4,0,30,5,0),colorgray;­

Var6:=FILTER(趨勢>=90,10);­

DRAWTEXT(Var6,40,'清倉'),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,'險'),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 趨勢<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;­

趨勢線: 趨勢,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(趨勢線,8);­

if(CROSS(Var2,Var18) AND Var2<15,50,0),COLORRED;­

DRAWTEXT(CROSS(趨勢線,Var2)AND 趨勢線>REF(趨勢線,1)AND 趨勢線<50,50,'追漲'),COLORFF0000;­

­

分析：這個公式輸出語句非常多，但多數(shù)都是用于趨勢判斷的。所以不用管它。仍按我們既定的思路進行。­

第一步｛從后往前找｝，先刪除發(fā)出信號關鍵語句之后的（紅色為輸出語句，它以下的語句已經刪去，藍色為等待下步刪除的）­

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);­

趨勢:=EMA(Var3,3)-10;­

FILLRGN(趨勢>80,趨勢,80);­

DRAWICON(CROSS(趨勢,0),0,1);­

FILLRGN((A09 > 0 AND (趨勢<20 OR 趨勢>REF(趨勢,1)AND 趨勢<50)),0,A09),colorFFFF00;­

機構建倉區(qū):0,LINETHICK0,colorFFFF00;­

Var4:=(趨勢-REF(趨勢,1))/REF(趨勢,1)*100;­

STICKLINE(趨勢<=13,0,20,5,0),colorcc9900;­

DRAWTEXT(FILTER(趨勢<=13,15),30,'準備現(xiàn)金'),colorcc9900;­

STICKLINE(趨勢<=13 AND Var4>13,0,50,5,0),color0099ff;­

Var5:=FILTER((趨勢<=13 AND Var4>13),10);­

DRAWTEXT(Var5,60,'買入'),color0099ff;­

­

第二步｛刪除沒用條｝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);­

趨勢:=EMA(Var3,3)-10;­

DRAWICON(CROSS(趨勢,0),0,1);­

Var4:=(趨勢-REF(趨勢,1))/REF(趨勢,1)*100;­

Var5:=FILTER((趨勢<=13 AND Var4>13),10);­

DRAWTEXT(Var5,60,'買入'),color0099ff;­

　­

第三步｛去掉修飾符后｝：­

趨勢:=EMA(Var3,3)-10;­

CROSS(趨勢,0);­

Var4:=(趨勢-REF(趨勢,1))/REF(趨勢,1)*100;­

Var5:=FILTER((趨勢<=13 AND Var4>13),10);­

Var5;­

第四步｛個別加等號｝本公式中的“條件”語句都是不輸出的，所以此項省略，但因是要笑臉和買入兩個信號，所以還必須把它們連結起來：­

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);­

趨勢:=EMA(Var3,3)-10;­

Var4:=(趨勢-REF(趨勢,1))/REF(趨勢
