你开仓信号用平仓周期来判断，那会有信号吗？不开仓会有平仓周期吗？

用全局变量来记录

variable:bj=0;

if bj=0 and holding=0 and 开多条件  then begin

   bj:=1;

end

if bj=0 and holding=0 and 开空条件  then begin

   buyshort.......;

   bj:=1;

end

if typebar(1,2)>10 and typebar(1,4)>10 and bj=1 and holding=0 and 开多条件 then buy.......;

if typebar(1,2)>10 and typebar(1,4)>10 and bj=1 and holding=0 and 开空条件 then buyshort....;
