求助一个简单问题

下面这段程序里面，有一行看不懂， (Bid-Level)Point是什么意思？(Bid-Level)和Point之间为什么没有运算符？ 谁能指点一下吗？谢谢！

int Delta=NormalizeDouble((Bid-Level)Point,0);

//-------------------------------------------------------------------------------------
// pricealert.mq4
// The code should be used for educational purpose only.
//-------------------------------------------------------------------------------------
int start() // Special function 'start'
{
double Level=1.3200; // Preset price level
int Delta=NormalizeDouble((Bid-Level)Point,0); // Excess
if (Delta<=0) // Price doesn't excess the level
{
Alert("The price is below the level"); // Message
return; // Exit start()
}
//-------------------------------------------------------------------------------------
switch(Delta) // Header of the 'switch'
{ // Start of the 'switch' body
case 1 : Alert("Plus one point"); break;// Variations..
case 2 : Alert("Plus two points"); break;
case 3 : Alert("Plus three points"); break;
case 4 : Alert("Plus four points"); break;//Here are presented
case 5 : Alert("Plus five points"); break;//10 variations 'case',
case 6 : Alert("Plus six points"); break;//but, in general case,
case 7 : Alert("Plus seven points"); break;//the amount of variations 'case'
case 8 : Alert("Plus eight points"); break;//is unlimited
case 9 : Alert("Plus nine points"); break;
case 10: Alert("Plus ten points"); break;
default: Alert("More than ten points"); // It is not the same as the 'case'
} // End of the 'switch' body
//-------------------------------------------------------------------------------------
return; // Exit start()
}
