编写要求：

老师您好:如何把通达信公式改编为飞狐用.麻烦了,谢谢!!T:=(C+L+H)/3;SL:=((REF(T,1)*REF(V,1)+T*V)/(REF(V,1)+V));VV:=SL;Y911:=IFF(CURRBARSCOUNT=1, (XMA(VV,9)*9-MA(VV,8)+MA(VV,7) -MA(VV,6)+MA(VV,5) -MA(VV,4)+MA(VV,3) -MA(VV,2) +VV)/9,XMA(VV,9));Y912:=IFF(CURRBARSCOUNT=1, (XMA(Y911,9)*9-MA(Y911,8)+MA(Y911,7) -MA(Y911,6)+MA(Y911,5) -MA(Y911,4)+MA(Y911,3) -MA(Y911,2) +Y911)/9,XMA(Y911,9));Y913:=IFF(CURRBARSCOUNT=1, (XMA(Y912,9)*9-MA(Y912,8)+MA(Y912,7) -MA(Y912,6)+MA(Y912,5) -MA(Y912,4)+MA(Y912,3) -MA(Y912,2) +Y912)/9,XMA(Y912,9));中期趋势:Y913,LINETHICK2,COLORGREEN;IF(Y913>REF(Y913,1),Y913,DRAWNULL),COLORMAGENTA,LINETHICK2;

解答：

INPUT:N(9,1,50);
