怎樣自編股票公式

從源碼中提取選股公式
　　口訣：從后往前找，刪除沒用條，去掉修飾符，個(gè)別加等號(hào)。
例一：找出買點(diǎn)
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(shuō)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(yǔ)句。然后看這條語(yǔ)句的基本條件。
　　　　　DRAWTEXT((CROSS(H1,H2) AND (CLOSE < EMA(CLOSE,60))),(LOW * 0.92),'買');
查看結(jié)果：輸出文字　　交叉　條件，條件　　　直 接 輸 出 語(yǔ) 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(guān)系的語(yǔ)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(wèn)題時(shí)再一次性刪除。加藍(lán)色的為找到的不輸出語(yǔ)句。
第二步｛刪除沒用條｝后，剩下的有用語(yǔ)句：
H1:EMA(CLOSE,8),LINETHICK1;　｛加藍(lán)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(biāo)線粗細(xì)、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(gè)別加等號(hào)｝　條件選股只能輸出一條語(yǔ)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(hào)后面加上等號(hào)，表達(dá)不輸出。結(jié)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(hào)
以本人發(fā)過(guò)的《跟莊建倉(cāng)》為例。
