The expert I attempted to run:
//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int init()
{
//----
//----
return(0);
}
//+------------------------------------------------------------------+
//| expert deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----
//----
return(0);
}
//+------------------------------------------------------------------+
//| expert start function |
//+------------------------------------------------------------------+
int start()
{
//----
//string Phrase = "The minimum lot size is ==>";
//double minlot = MarketInfo(Symbol(),MODE_MINLOT);
//MessageBox(Phrase + minlot);
//----
MessageBox("The minimum lot size is ==>" + MarketInfo(Symbol(),MODE_MINLOT));
return(0);
}
//+------------------------------------------------------------------+
However, I fixed it using this code...
//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int init()
{
//----
//----
return(0);
}
//+------------------------------------------------------------------+
//| expert deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----
//----
return(0);
}
//+------------------------------------------------------------------+
//| expert start function |
//+------------------------------------------------------------------+
int start()
{
//----
string Phrase = "The minimum lot size is ==>";
double minlot = MarketInfo(Symbol(),MODE_MINLOT);
MessageBox(Phrase + minlot);
//----
return(0);
}
//+------------------------------------------------------------------+
This is very strange.......................
