通达信MACD底背离二次金叉公式

（一）通达信MACD底背离、金叉、二次金叉
 MACD:=("MACD.DIF"-"MACD.DEA")*2*60;
 JCCOUNT:=COUNT(CROSS("MACD.DIF","MACD.DEA"),BARSLAST("MACD.DEA">=0));
 二次金叉:=CROSS("MACD.DIF","MACD.DEA") AND "MACD.DEA"<0 AND COUNT(JCCOUNT=2,21)=1;
 A101:=BARSLAST(REF(CROSS("MACD.DIF","MACD.DEA"),1));
 底背离:=REF(CLOSE,A101+1)>CLOSE AND "MACD.DIF">REF("MACD.DIF",A101+1) AND CROSS("MACD.DIF","MACD.DEA");
 XG:二次金叉 AND 底背离;
