底背离是指当股价指数逐波下行，而DIF及MACD死叉不是同步下降，而是逐波上升，与股价走势形成底背离，预示着股价即将上涨。如果此时出现DIF两次由下向上穿过MACD，形成两次黄金股交叉，则股价即将大幅度上涨。那么底背离选股公式是什么呢？
{底背离}
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);DEA:=EMA(DIFF,9);MACD:=2*(DIFF-DEA);QZQ:=BARSLAST(REF(MACD,1)<0ANDMACD>0);QM:=LLVBARS(MACD,QZQ+20);MQDZ:=IF(QM>QZQ,REF(MACD,QM),0);XG1:=MACD<0ANDMACD>MQDZANDCLOSE=LLV(CLOSE,QZQ+20)ANDMQDZ<0;XG:REF(XG1,1)=1ANDMACD>REF(MACD,1)
{双底背离}
DIFF:=EMA(CLOSE,12)-EMA(CLOSE,26);DEA:=EMA(DIFF,9);MACD:=2*(DIFF-DEA);QZQ:=BARSLAST(REF(MACD,1)<0ANDMACD>0);QM:=LLVBARS(MACD,QZQ+20);MQDZ:=IF(QM>QZQ,REF(MACD,QM),0);QF:=LLVBARS(DIFF,QZQ+20);DQDZ:=IF(QF>QZQ,REF(DIFF,QF),0)
XG1:=MACD<0ANDMACD>MQDZANDDIFF<0ANDDIFF>DQDZANDCLOSE=LLV(CLOSE,QZQ+20)ANDMQDZ<0ANDDQDZ<0;XG:REF(XG1,1)=1ANDMACD>REF(MACD,1)
底双背离是指MACD(绿柱)和DIFF(黄白线)都底背离。
一、放心追涨：M:=MA(CLOSE,5);MA2:=MA(CLOSE,10);MA3:=MA(CLOSE,20);MA4:=MA(CLOSE,30);MA5:=ma(close,60);:=(C-O)/O;C1:=IF(REF(O,1)〈REF(M,1)ANDREF(O,1)〈REF(MA2,1)ANDREF(C,1)〉REF(M,1)ANDREF(C,1)〉REF(MA2,1),1,0);C2:=IF(REF(M,1)〉REF(MA3,1)ANDREF(MA2,1)〉REF(MA3,1),1,0);C3:=IF(C-O〉0ANDC〉MANDC〉MA2ANDVOL〉1.4*REF(VOL,1)ANDC〉MA5ANDC〉REF(C,10),1,0);C4:=IF(〈REF(,1)ANDO〈REF(C,1),1,0);C1〉0ANDC2〉0ANDC3〉0andC4〉0
二、放胆追高
M:=MA(C,5);MA2:=MA(C,10);MA3:=MA(C,20);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;:=IF(M〉REF(M,1)ANDREF(M,1)〉REF(M,2)AND1.7*(REF(M,1)-REF(M,2))〈(M-REF(M,1)),1,0);A2:=IF(1.5*(REF(MA2,1)-REF(MA2,2))〈(MA2-REF(MA2,1)),1,0);A3:=IF(M-MA2〉1.3*REF(M-MA2,1)ANDMA3〉LLV(MA3,10),1,0);A4:=IF(C〈0.7*HHV(H,60)ANDREF(HHV(C,60),60)〉0.5*HHV(C,60),1,0);A5:=IF(HHV(C,60)-LLV(C,60)/HHV(C,60)〈0.15ORHHV(MA3,20)〉REF(HHV(MA3,20),20),1,0);〉0ANDA2〉0ANDA3〉0ANDA4+A5〉0ANDK〈85ANDJ〈100ANDK〉REF(K,1)ANDREF(k,1)〉REF(K,2)
三、均线股市追涨
M:=MA(CLOSE,5);MA2:=MA(CLOSE,10);MA3:=MA(CLOSE,20);MA4:=MA(CLOSE,30);MA5:=ma(close,60);MA6:=ma(close,120);:=(C-O)/O;C1:=IF(REF(O,1)〈REF(M,1)ANDREF(O,1)〈REF(MA2,1)ANDREF(C,1)〉REF(M,1)ANDREF(C,1)〉REF(MA2,1),1,0);C2:=IF(REF(M,1)〉REF(MA3,1)ANDREF(MA2,1)〉REF(MA3,1),1,0);C3:=IF(C-O〉0ANDC〉MANDC〉MA2ANDVOL〉1.4*REF(VOL,1)ANDC〉MA5ANDC〉REF(C,10),1,0);C4:=IF(〈REF(,1)ANDO〈REF(C,1),1,0);C1〉0ANDC2〉0ANDC3〉0andC4〉0
我们通过函数的计算，给大家统计了关于底背离选股的公式，当然理财君还是要和大家说，股票投资有风险，虽然理论我们很清楚，但是实际操作还是要谨慎处理，毕竟股票投资行确实存在很大风险。
