MACD在前面50个K线，DIF与DAE已经有两次金叉或者死叉怎么表示？请老师帮我编一个！谢谢！
input:p(26,20,100,8),s(12,5,40,4),m(9,2,60,6);
DIFF :EMA(CLOSE,S) - EMA(CLOSE,P);
DEA :EMA(DIFF,M);
MACD1 :2*(DIFF-DEA), COLORSTICK;
macdjc:cross(diff,dea),NODRAW;//macd金叉
macdsc:cross(dea,diff),NODRAW;
result1:count(macdjc,50)>=2;//金叉2次。
result2:count(macdsc,50)>=2;//死叉2次
