主题：恳请老师帮忙编写策略

 先看交易的代码吧。K线变色回头空了再弄，那个太繁琐了。

ma5:ma(c,5);
ma25:ma(c,25);

majc:cross(ma5,ma25);
masc:cross(ma25,ma5);


if majc then
begin
sellshort(holding<0,holding,market);
buy(holding=0,1,market);   
end

if masc then
begin
sell(holding>0,holding,market);
buyshort(holding=0,1,market);   
end


if  ref(llv(c,10),1)>c then 多头止损:sell(1,holding,market);
if  ref(hhv(c,10),1)<c then 空头止损:sellshort(1,holding,market);
