Hello dear Support,

This bug regards Standalone API not Desktop platform.

I noticed that NullPointerException is thrown on double click on Stop Loss or Take Profit Line on chart launched from Standalone API.

It would be perfect if methods stopLossClicked(IOrder o) and takeProfitClicked(IOrder o) where triggered on such actions instead of exception

The exception:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Please provide the example program which you launch.

Hi,

I use program from Wiki page: https://www.dukascopy.com/wiki/files/MainOpenChart.java

I just modified following lines in IStrategy.onStart method to ensure there are open orders on the chart with SL and TP limits.

IChart chart = context.getChart(instrument);                               

if (chart != null) {
        System.out.println(chart.getFeedDescriptor() + " " + tick);

        if (engine.getOrders(instrument).size()==0) {                                
            engine.submitOrder(
                    "Order#" + counter++, 
                    instrument, 
                    IEngine.OrderCommand.BUY, 
                    0.001,
                    0,
                    -1.0,
                    tick.getBid()-10*instrument.getPipValue(), 
                    tick.getAsk()+10*instrument.getPipValue());
        }                                        
}

I attach a screenshot of chart before double click on SL line and after.

After SL line is clicked, SL disappears and exception is thrown like in initial post.

best regards,
Kurak
