DEA 0线 (文华财经WH8赢智V8.2)来源:文华财经 日期:2018-7-13 9:51
DEA 大于 0线第一次金叉开多，DEA 小于 0线第一次死叉开空，其他交叉不出信号，求教程序编写方法
请参考：DIFF :EMA(CLOSE,12) - EMA(CLOSE,26);
DEA : EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
N1:=BARSLAST(CROSS(DEA,0))+1;
N2:=BARSLAST(CROSSDOWN(DEA,0))+1;
COUNT(CROSS(DEA,DIFF),N1)=1&&CROSS(DEA,DIFF)&&N1<N2,BPK;
COUNT(CROSSDOWN(DEA,DIFF),N2)=1&&CROSSDOWN(DEA,DIFF)&&N1>N2,SPK;
AUTOFILTER;
