DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);
MACD:=(DIF-DEA)*2;
VA1:=HHVBARS(MACD,BARSLAST(MACD<0)+1);
VA2:=CROSS(BACKSET(CROSS(0,MACD) OR (ISLASTBAR AND MACD>0),REF(VA1,1)+2),0.5);
VA3:=LLVBARS(MACD,BARSLAST(MACD>0)+1);
VA4:=CROSS(BACKSET(CROSS(MACD,0) OR (ISLASTBAR AND MACD<0),REF(VA3,1)+2),0.5);
卖:VA2;
买:VA4;
