mytrader上的一個老模型如何翻譯成現在麥語言的模型？

PARAM[SHORT,1,100,5]
PARAM[LONG,1,100,8]
PARAM[M,1,100,13]

DIFF := EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);
DEA  := EMA(DIFF,M);
MMACD:=2*(DIFF-DEA),COLORSTICK;

CROSS(DIFF,DEA),bp;
CROSS(DIFF,DEA) && DEA>0,bk;
CROSS(DEA,DIFF),sp;
CROSS(DEA,DIFF) && DEA<0,sk;

 DIFF := EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);
DEA  := EMA(DIFF,M);
MMACD:=2*(DIFF-DEA),COLORSTICK;
CROSS(DIFF,DEA),BP;
CROSS(DIFF,DEA) && DEA>0,BK;
CROSS(DEA,DIFF),SP;
CROSS(DEA,DIFF) && DEA<0,SK;
AUTOFILTER;

按照原來的參數在右側參數列表分別設置 SHORT  LONG  M 的值
