主题：[求助]求帮忙写公式，谢谢啦！

VARIABLE:n=0,ying=0,kui=0;

jc:cross(dea,diff);//金叉
sc:cross(diff,dea);//死叉

if date<>ref(date,1) then begin //第二天重置为0重新计算
 n:=1;

 end

if jc and n<=5 then begin //限制最多5手
buy(holding=0,n,market);
end

if sc then begin
sell(holding>0,holding,market);
if numprofit(1)>0 then begin//盈利n赋值为1手
n:=1;
ying:=numprofit(1)+ying;//盈利的和
end

if numprofit(1)<0 then begin //亏损n+1手
 n:=n+1;
 kui:=numprofit(1)+kui;//亏损总数
 end
end
if n>=5 then n:=5;
