标题：请老师帮忙写个移动止损

多或空开仓后亏2%止损，盈利3%以上后把止损移致成本价。。。盈利超3%以上后回撤未到成本价不止盈（损）。

if holding>0 and c<=enterprice*0.98 then sell(1,0,market);

if holding<0 and c>=enterprice*1.02 then sellshort(1,0,market);

 

if holding>0 and hhv(h,enterbars+1)>=enterprice*1.03 and c<enterprice then sell(1,0,market);

if holding<0 and llv(l,enterbars+1)<=enterprice*0.97 and c>enterprice then sellshort(1,0,market);
