标题：关于加仓

老师，请问加仓及加仓次数限制如何写？我使用日线趋势模型，买入信号出现开1手（比如ma1>ma2)，之后每盈利50点（50*mindiff)加1手,最多允许加3次仓，且每日最多只能加1次.

yl:=c-enterprice;

if holding>0 and yl>=50*mindiff and yl<100 then buy(holding=1,1,market);

if holding>0 and yl>=100*mindiff and yl<150 then buy(holding=2,1,market);

if holding>0 and yl>=150mindiff and yl<200hen buy(holding=3,1,market);
