题材来源：MACDLUNTANG 无偿介绍一种方法，MACD和KDJ和阴量（阴K线）的组合；
原作者思路：
首先给公式：
KDJ：
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=SMA(RSV,3,1);
D:=SMA(K,3,1);
J:=3*K-2*D;
AA1:=J<0 AND REF(J,1)>0 AND REF(J,2)>0;
DIFF:=100*EMA(CLOSE,12)-100*EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
AA2:=MACD>REF(MACD,1) AND REF(MACD,1)>REF(MACD,2) AND REF(MACD,2)>REF(MACD,3) AND REF(MACD,3)>REF(MACD,4);
COND1:=BARSLAST(AA1);
COND2:=BARSLAST(AA2);
COND3:=CLOSE<OPEN;
BUY_SIGNAL:COND2>0 AND COND2<COND1 AND COND1-COND2>=3 AND COND3 AND REF(COND2,1)=0 AND REF(COND3,1)=0;
