這個暫定的寫法比想象中復雜，我先試試看

variable:n=0;
ma5:=ma(c,5);
ma10:=ma(c,10);
X:=5;
Y:=10;
if cross(ma5,ma10) and n=0 and holding=0 then begin
 buy(holding=0,1,market);
 n:=1;
end

IF cross(ma5,ma10) and n=1 and holding=0 and barpos-n>Y then buy(holding=0,1,market);
if cross(ma10,ma5) and holding>0 and n=1 then begin

    if openprofit>x*MULTIPLIER then begin

           sell(1,0,market);

           n:=barpos;

    end

    if openprofit<=x*MULTIPLIER then begin

            sell(1,0,market);

            buyshort(holding=0,1,market);

    end

end
