Hello Support,

I would like to register a bug on JForex Desktop platform. The bug reveals when orders are being partially closed and starting and stopping a strategy.

The bug reveals at many different scenarios however following is the most certain:
1. Trade at market EURUSD at least 10.000 units.
2. Run attached strategy.
3. Stop the strategy.

Repeat above steps until NullPointerException is thrown at Messages Tab (usually the bug reveals between 3rd to 10th repetitions).

The result of the bug is not only the Exception. When you look at top line message of Strategy message tab you will see that order details are wrong (profit in currency is 0, amount of the order is 0). Every new run of any strategy will return the same wrong details for the order and it is not possible to close such order from any strategy. In order to have correct results again one need to close JForex Desktop and start it again.

I am attaching:
1. Java traces
2. Strategy code
3. Strategy message tab
4. JForex message tab.
5. Screenshot of the platform after bug occurrence.

Could you please investigate?

Best regards,
Kurak

Hello Support,

Did you manage to reproduce above bug?

It is very serious issue making it unable to perform reliable trade management. The best example would be following screenshot of JForex with the custom developed tab which presents currently FILLED orders. Please compare it to original tab. The amount column is totally wrong. There are negative amount values! What’s more there is no possibility to perform any operation on such order from strategy code (it is not possible to modify SL, TP nor close the trade).

At the beginning I though there is something wrong with my app. But then I run the simplest possible strategy with following code in onStart method which showed exactly the same wrong values.
        for (IOrder o : engine.getOrders()){
            if (o.getState() == State.FILLED){
                console.getOut().println(o.getId() + " amount: " + o.getAmount());
            }
        }       

Could you please confirm you can reproduce scenario from first post and registered the issue as a bug?

Best regards,
Kurak
