＋

加法

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high+Price("m1109","New");//表示求m1109当前最高价及当前价格的和。
}

－

减法

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high-Price("m1109","New");//表示求m1109当前最高价及当前价格的差。
}

*

乘法

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high*Price("m1109","New");//表示求m1109当前最高价及当前价格的乘积。
}

/

除法

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high/Price("m1109","New");//表示求m1109当前最高价及当前价格的商。
}

&&

并且运算

VAR high,low;
VOID MAIN()
{
high=High("m1109","High");//high的值为合约m1109当前最高价 low=Price("m1109","Low");//low的值为合约m1109当前最低价 high>Price("m1109","New")&&low<Price("m1109","New");//表示判断m1109当前最高价是否大于价格，并且，最低价小于当前价格。
}

||

或者运算

VAR high,low;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
low=Price("m1109","Low");//low的值为合约m1109当前最低价
high>Price("m1109","New")||low<Price("m1109","New");//表示判断m1109当前最高价是否大于价格，或者，最低价小于当前价格。
}

> 

大于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high>Price("m1109","New");//表示判断m1109当前最高价是否大于当前价格。
}

< 

小于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high<Price("m1109","New");//表示判断m1109当前最高价是否小于当前价格。
}

>=

大于等于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high>=Price("m1109","New");//表示判断m1109当前最高价是否大于等于当前价格。
}

<=

小于等于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high<=Price("m1109","New");//表示判断m1109当前最高价是否小于等于当前价格。
}

!=

不等于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high!=Price("m1109","New");//表示判断m1109当前最高价是否不等于当前价格。
}

==

等于运算

VAR high;
VOID MAIN()
{
high=Price("m1109","High");//high的值为合约m1109当前最高价
high==Price("m1109","New");//表示判断m1109当前最高价是否等于当前价格。
}

=

为变量进行赋值

VAR Price;
VOID MAIN()
{
Price=Price("m1109","New");//表示将合约m1109的当前价格赋值给Price变量。
}
