主题：请问跨周期，macd4小时第一次金叉死叉后，15分钟的kd的K值在25以下做多，75以上做空

variable:n=0,m=0;

diff:=stkindi('','macd.diff',0,24,4);

dea:=stkindi('','macd.dea',0,24,4);

k:=stkindi('','kdj.k',0,datatype);

d:=stkindi('','kdj.d',0,datatype);

金叉:cross(diff,dea);

死叉:cross(dea,diff);
if 金叉 or 死叉 then begin

   n:=0;

   m:=0;

end

if k<25 then n:=n+1;

if k>75 then m:=m+1;

if n=1  then begin

     sellshort(1,0,marketr);

     buy(holding=0,1,marketr);

end

if m=1 then begin

     sell(1,0,marketr);

     buyshort(holding=0,1,marketr);

end
