编写要求：

VA:=IF(CLOSE>REF(C,1),VOL,-VOL); A:=BARSCOUNT(LLV(LOW,0)); OBV:=SUM(IF(CLOSE=REF(CLOSE,1),0,VA),A); MAOBV:=MA(OBV,26); MAOBV13:=MA(OBV,12); DIF:MAOBV13-MAOBV; DEA:EMA(DIF,9); IF(DEA>=REF(DEA,1),DEA,DRAWNULL),COLORRED,LINETHICK2; IF(DIF>=REF(DIF,1),DIF,DRAWNULL),COLORRED,LINETHICK1; MACD:(DIF-DEA)*2,COLORSTICK; 0;

解答：

?VA:=IF(CLOSE>REF(C,1),VOL,-VOL);

A:=BARSLAST(L=LLV(LOW,0));
