The exclamation marker is a logical negation NOT for boolean operation (click that). In simple word, the exclamation marker mean boolean false.

bool Global_Warming == true;

if (! Global_Warming ) //--- read : if Global_Warming equal false ==>> if (Global_Warming == false)
   {
   Print ("Global warming is not true");
   }

So question to you, " What is the return type of OrderCalcMargin ?
