Hi,

I have a problem that I cannot solve. I make an order in EUR/USD for 1 lot,
in the onMessage function I call order.getRequestedAmount once and order.getAmount once.
The order state is ORDER_FILLED.
getRequestAmount returns me 0.9999999
getAmount return me 0.999999
So the is one more nine in getRequestAmount.
So when I compare this two amounts to check if order has been filled totally (which is the case), result do not match.
The same happens for lot size of: 0.1,0.2 etc...

Do you have a solution ?

        if(messageOrder.getState() == IOrder.State.FILLED) {
                double o = messageOrder.getRequestedAmount();
                double a = messageOrder.getAmount();
                DecimalFormat df = new DecimalFormat("0.00000000000000000000");
                console.getOut().println(key + " : order amount: "+df.format(o));
                console.getOut().println(key + " : order requested amount: "+df.format(a));
                int result = Double.compare(o, a);
                if(result != 0) {
                    console.getOut().println(key + " : Order amounts do not match !");
                    messageOrder.setRequestedAmount(0);
                }
        }

order requested amount outputs: 0.99999990000000000000
order mount outputs: 0.99999900000000000000

Of course every time I get the print: Order amounts do not match !

Many thanks in advance for any answer.

See:
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

For double comparison use:
https://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Double.html#compare(double,%20double)

Hi,

Thanks for your reply.
I just copied the sample code from the docs. All the samples do not use BigDecimal.
My new code is:

   IOrder messageOrder = message.getOrder();
       if(messageOrder.getState() == IOrder.State.FILLED) {
       BigDecimal o = new BigDecimal(originalOrder.getRequestedAmount());
       BigDecimal a = new BigDecimal(originalOrder.getAmount());
       if(!o.equals(a)) {
          console.getOut().println("Amounts do not match !");
          messageOrder.setRequestedAmount(0);
       }
    }

I still get the difference.


getRequestedAmount and getAmount do return double data type.
By the way all methods from API do return double.

How can I proceed ?

P.S. I enter my order as follows:

   IOrder order = engine.submitOrder(label, instrument, oCommand, 1, price, 2, stopLoss, 0);

You are mixing here two things - o.equals(a) compares two objects, not their values, for BigDecimal comparison use:
https://docs.oracle.com/javase/1.4.2/docs/api/java/math/BigDecimal.html#compareTo(java.math.BigDecimal)
There is less hustle if you use the method that we suggested before:
https://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Double.html#compare(double,%20double)
Please read its documentation and find usage examples.
Because they are precise enough for the purpose they are used, you only need to take care when:

1. Comparing to another value.
2. Printing the values, see examples: https://www.dukascopy.com/wiki/#IConsole/Logging_values.
