主题：请教关于成交量的模型应该怎样写？

//本周期收盘价平空进多
if c3>o3 and v1>1000 and v1=2*ma5v then 

//拟修改为 if c3<o3 and v3>1000 and v3大于3周期前ma5v的两倍。例：if c3<o3 and v3>1000 and v3>2*ma5v3

 begin
    sellshort(holding<0,0,thisclose);
    buy(holding=0,1,thisclose);
 end

if holding>0 then p1:=enterprice;
//止损为持仓价之下N点;
if holding>0 then sell(1,0,stopr,p1-N);

//拟修改为 if c1>o1 and v1>1000 and v1大于上周期ma5v的两倍.例：c1>o1 and v1>1000 and v1>2*ma5v1
 begin
    sell(holding>0,0,limitr,o);
    buyshort(holding=0,1,limitr,o);
 end
 
if holding<0 then p2:=enterprice;
//止损为持仓价之上N点;
if holding<0 then sellshort(1,0,stopr,p2+N);
