What is going on here?
I am printing the following statement:
Print(Order_Symbol, ",", Order_Quantity, ",",(OrderType() == 1),",", (Order_Quantity == 0));
It returns (symbol, 0, 1, 0)
How can Order_Quantity = 0 and Order_Quantity != 0 in the same statement? Order_Quantity is declared as a double variable.
I have a possible answer to your question . . . . . try this:
Print(Order_Symbol, ",", Order_Quantity, ",",(OrderType() == 1),",", (NormalizeDouble(Order_Quantity, Digits) == 0));
Print will do this . . . "Data of double type are printed with 4 decimal digits after point." so if your variable Order_Quantity is 0.00000001 it is != 0 but will print as 0 . . . you need to be careful comparing double values, precision issues can catch you out, they have caught me out in the past and I learned a good lesson.
RaptorUK is exactly right with the exception on a 5 digit broker if quantity was 0.0000x, quantity will print as 0 but normalize(digits)==0 will still print 0.

- It is never ever necessary to use normalize.
double minLot = MarketInfo(Symbol(), MODE_MINLOT); if (Order_Quantity < minLot){ // Effectually zero
