DIFF:=EMA(CLOSE,) - EMA(CLOSE,);
DEA:=EMA(DIFF,);
MACD:=*(DIFF-DEA);
QZQ:=BARSLAST(REF(MACD,)< AND MACD>);
QM:=LLVBARS(MACD,QZQ+);
MQDZ:=IF(QM>QZQ,REF(MACD,QM),);
XG1:=MACD< AND MACD>MQDZ
 AND CLOSE=LLV(CLOSE,QZQ+) AND MQDZ<;
XG:REF(XG1,)= AND MACD>REF(MACD,);

{双底背离,通达信版、同花顺版}
DIFF:=EMA(CLOSE,) - EMA(CLOSE,);
DEA:=EMA(DIFF,);
MACD:=*(DIFF-DEA);
QZQ:=BARSLAST(REF(MACD,)< AND MACD>);
QM:=LLVBARS(MACD,QZQ+);
MQDZ:=IF(QM>QZQ,REF(MACD,QM),);
QF:=LLVBARS(DIFF,QZQ+);
DQDZ:=IF(QF>QZQ,REF(DIFF,QF),);
XG1:=MACD< AND MACD>MQDZ AND DIFF< AND DIFF>DQDZ
 AND CLOSE=LLV(CLOSE,QZQ+) AND MQDZ< AND DQDZ<;
XG:REF(XG1,)= AND MACD>REF(MACD,);
