主题：请问如何实现下面想法

hv:hhv(c,ENTERBARS+1);//仅以收盘价计算持仓后的最高点，也可以改成最高价
cd1:hv>AVGENTERPRICE and (hv-c)/hv>=0.06;

if cd1 and holding>0 then
begin
sell(1,holding,market);
buyshort(holding=0,1,market);    
END

lv:llv(c,ENTERBARS+1);//仅以收盘价计算持仓后的最低点，也可以改成最低价
cd2:=lv<AVGENTERPRICE and (c-lv)/lv>=0.06;

if cd2 and holding<0 then
begin
sellshort(1,holding,market);
buy(holding=0,1,market);    
END
