条件选股公式：
macd,RSi,kdj底背离
KDJ_K:="KDJ.K"(9,3,3);KDJ_D:="KDJ.D"(9,3,3);KDJ_J:="KDJ.J"(9,3,3);
买1:=CROSS(KDJ_J,0) OR (CROSS(KDJ_J,KDJ_K) AND KDJ_D<26);
买2:=CROSS("RSI.RSI1"(6,2,2),20) OR CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24));
买3:=CROSS("MACD.DIF","MACD.DEA") OR CROSS("MACD.MACD",0);
买0:=买1+买2+买3;
买:IF(买0>1,买0,0);

1）KDJ和RSI在20以下钝化一段时间；2）MACD绿线逐渐缩短，且DIF上穿DAE而DEA也向上运行；3）日线向SAR靠拢并交叉；4）ROC在超卖区上穿MROC并且MROC上行；5）BOLL开口放大；6）5日线走平并上穿10日线且10日线走平并向上。
试着将上述条件编成一公式，经测试，结果为零。于是，删除并放宽一些条件，有如下公式：
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
AA1:=DIFF<0 AND DIFF>=DEA AND DEA>REF(DEA,1)AND MACD>REF(MACD,1);
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
AA2:=3*K-2*D<25;
LC:= REF(CLOSE,1);
AA3:=SMA(MAX(CLOSE-LC,0),6,1)/SMA(ABS(CLOSE-LC),6,1)*100<30;
ROC:=(CLOSE-REF(CLOSE,12))/REF(CLOSE,12)*100;
ROCMA:=MA(ROC,6);
AA4:=ROCMA<0 AND ROC>=ROCMA AND ROCMA>REF(ROCMA,1);
AA5:=C<SAR(10,2,20)OR CROSS(C,SAR(10,2,20));
MID:=MA(CLOSE,26);
UPPER:=MID+2*STD(CLOSE,26);
AA1 AND AA2 AND AA3 AND AA4 AND AA5;
大家可再减少一些条件试试，信号会逐步增多。比如去掉最后两个后，成功率仍是百分之百，而信号由6个增加到10个。
