以下公式适合通达信股票软件。选出股票后能否买入依然还要综合参考大趋势和其它指标。
金叉并非万能，有时刚刚进入金叉或准金叉状态，也可能是上一波反弹的结束，下一波下跌的开始。
只有当金叉周期的前后周期均为上涨趋势，金叉的威力才最大。
业绩的持续增长才是技术指标的前提和保证。
1、0轴上方第一次金叉选股公式：
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA := EMA(DIFF,9);
macd := 2*(DIFF-DEA);
xg:cross(diff,dea) and dea>-1.0 and dea<0.5 and CLOSE>ref(CLOSE,1) and CLOSE>=ma(c,60);
或：
DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
XG:DIF>0 AND DEA>0 AND CROSS(DIF,DEA);
2、0轴上方二次金叉的选股公式：
JC:IF(SUM(IF(MACD>0 AND CROSS(MACD.DIF,MACD.DEA),1,0),0)-HHV(IF(IF(CROSS(MACD.DEA,0),1,0),
SUM(IF(MACD>0 AND CROSS(MACD.DIF,MACD.DEA),1,0),0),0),0)=2 AND SUM(IF(MACD>0 AND CROSS(MACD.DIF,MACD.DEA),1,0),
0)>REF(SUM(IF(MACD>0 AND CROSS(MACD.DIF,MACD.DEA),1,0),0),1),10,0);
{选股设JC=10即可}
3.0轴下方一次金叉的选股公式：
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=(DIFF-DEA)*2;
低位金叉:CROSS(DIFF,DEA) AND DIFF<-0.1;
4、0轴下方二次金叉且第二次金叉高于第一次金叉：
DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
AA:=BARSLAST(REF(CROSS(DIF,DEA),1));
二次金叉:CROSS(DIF,DEA) AND DIF>REF(DIF,AA+1) AND AA<20 AND DIF<0;
5、0轴下方二次金叉选股公式：
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26); {选股设JC=10即可}
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
A:=IF(CROSS(0,DEA),1,0);
A1:=IF(DIFF<0 AND CROSS(DIFF,DEA),1,0);
SS:=IF(A,SUM(A1,0),0);
SSB:=HHV(SS,0);
SSS:=SUM(A1,0);
JC:IF(SSS-SSB=2 AND SSS>REF(SSS,1),10,0);
6、缩量横盘突破选股：

WH03:=REF(WH01,1);
WH04:=HHVBARS(HIGH,55)>20 OR C=HHV(H,55);
WH05:=WH02 AND WH03 AND WH04 AND C>REF(HHV(H,10),1);
WH05 AND REF(NOT(WH05),1);
7、均线、kdj、MACD金叉的预警选股公式
完全符合以下条件：
1、5日线上穿10日线
2、MACD金叉
3、kdJ金叉（KDJ数值由9、3、3调整为8、2、2）
4、成交量指标金叉
通达信预警选股公式
A1:=CROSS(MA(C,5),MA(C,10));
A2:=CROSS(MACD.DIF,MACD.DEA);
A3:=CROSS(KDJ.K(8,2,2),KDJ.D(8,2,2));
A4:=CROSS(MA(V,5),MA(V,10));
XG:A1 AND A2 AND A3 AND 4;
三金叉选股完整源码，绝无未来函数
均线、成交量、MACD同时金叉
MA1:=MA(CLOSE,5);
MA2:=MA(CLOSE,10);
AA:=CROSS(MA1,MA2);
AAA:=COUNT(AA,3)>=1;
T1:=MA(VOL,5);
T2:=MA(VOL,10);
BB:=CROSS(T1,T2);
BBB:=COUNT(BB,3)>=1;
DIF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIF,9);
MACD:=(DIF-DEA)*2;
CC:=CROSS(DIF,DEA);
CCC:=COUNT(CC,3)>=1;
三金:=AAA AND BBB AND CCC;
三金叉:FILTER(三金,3),COLORFF00FF;
使用说明：该选股公式适合超级短线，快进快出具有一定的风险因素，此时的股价往往处于拉高拔升阶段。
要求使用者特别关注股价所处的位置，如果过于高位防止庄家诱多。低位可大胆搏杀，短期回档被套也有回旋余地。

18、条件选股公式：(双佛手向上) 缺省周期：日线
======================================================================
DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
DEA := EMA(DIFF,27);
MACD := 2*(DIFF-DEA);
CLOSE>OPEN AND MA(CLOSE,5)>MA(CLOSE,10) and MA(CLOSE,10)>MA(CLOSE,30)
and DIFF>DEA AND MACD>REF(MACD,1) and DIFF>0 AND DEA>0 and MA(VOL,5)>MA(VOL,34)
and MA(CLOSE,30)>=REF(MA(CLOSE,30),1)=======================================================================================
根据《南征北战之二》中的双佛手向上思路编写，指标用法：
1.DIFF线回调DEA线附近时不死叉，又调头向上。
2.30日均线走平或向上，同时5日线和10日线在30日线上方金叉,且当日收阳线。
3.5日均量线回调到34日均量线附近时不死叉,又调头向上。
以上三个条件要同时成立时将有一波上升浪，应果断买入。
将MACD指标的m参数调为27
19、条件选股公式：(漫步青云) 缺省周期：日线
======================================================================
DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
DEA := EMA(DIFF,27);
dje:=DIFF>=0 and DEA>=0 and CROSS(DIFF,DEA);
a5:=MA(CLOSE,5)>MA(CLOSE,10);
v5:=VOL>MA(VOL,5) and MA(VOL,5)>MA(VOL,10);
dje and a5 AND V5 AND MA(CLOSE,30)>=REF(MA(CLOSE,30),1) ======================================================================
将macd指标的参数调为12,26,27
主要用法：当30日均线走平或上扬，5日均量大于10日均量，当日成交量大于5日均量，
5日均线金叉或已金叉10日均线，macd指标中diff线在0轴上死叉dea线，DIFF线下穿0轴后，又再次上穿并在0轴或0轴上金叉dea线，应果断介入。
但若此时k线离30日，30周,30小时均线较远，不能介入
20、======================================================================
条件选股公式：(空中缆绳) 缺省周期：日线
======================================================================
DIFF := EMA(CLOSE,12) - EMA(CLOSE,26);
DEA := EMA(DIFF,27);
MACD := 2*(DIFF-DEA);
b:=MIN(DIFF,DEA)/MAX(diff,dea)>0.95;
MA(CLOSE,30)>REF(MA(CLOSE,30),1) and diff>0 and dea>0 AND MACD>REF(MACD,1) and b
======================================================================
将MACD指标的参数调为sh:12;long:26;M:27
用法:30日均线上扬或走平，主力开始洗盘。
这时macd指标中的DIFF线随股价的回调而与DEA线在0轴上粘合数值几乎相等，只要5日均线在30日均线上方金叉或已金叉10日均线，macd指标红柱加长，DIFF线脱离DEA线上扬,就是买点。
