1）KDJ和RSI在20以下鈍化一段時間；2）MACD綠線逐漸縮短，且DIF上穿DAE而DEA也向上運行；3）日線向SAR靠攏并交叉；4）ROC在超賣區上穿MROC并且MROC上行；5）BOLL開口放大；6）5日線走平并上穿10日線且10日線走平并向上。
試著將上述條件編成一公式，經測試，結果為零。于是，刪除并放寬一些條件，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;
大家可再減少一些條件試試，信號會逐步增多。比如去掉最后兩個后，成功率仍是百分之百，而信號由6個增加到10個。
