if 金叉 then
begin
//平空开多
sellshort(holding<0 and ccm,0);
buy(holding<=0,1);
end

if 死叉 then
begin
//平多开空
sell(holding>0 and cmc,0);
buyshort(holding>=0,1);
end

我改成

sellshort(金叉 and holding<0 and ccm,0);
buyshort(死叉 and holding>=0,1);

buy(金叉 and holding<=0,1);

sell(死叉 and holding>0 and cmc,0);

执行效果有什么不同吗？

如果有不同~原因是什么？

========================

写法1

sellshort(金叉 and holding<0 and ccm,0);  //语句1
buyshort(死叉 and holding>=0,1);//语句2

buy(金叉 and holding<=0,1);//语句3

sell(死叉 and holding>0 and cmc,0);//语句4

写法2

sellshort(金叉 and holding<0 and ccm,0)，ORDERQUEUE;
buyshort(死叉 and holding>=0,1)，ORDERQUEUE;

buy(金叉 and holding<=0,1)，ORDERQUEUE;

sell(死叉 and holding>0 and cmc,0)，ORDERQUEUE;

写法1跟写法2有啥不同？

难道不用ORDERQUEUE的话

交易指令的执行就不是按照语句1 语句2 语句3...的顺序执行的吗？
