Hi,

I use eclipse for my main programming, and test using both ITesterUserInterface and the JForex standalone gui.

I want to programatically add my custom indicator to the chart - so it loads on startup in both modes. I make the call:

            context.getIndicators().registerCustomIndicator(MyIndicator.class);
           IIndicator myCustom = context.getIndicators().getIndicator("MYIND1");
           chart.addIndicator(myCustom, new Object[]{4});


However, this fails miserably on the call to addIndicator() with:
SEVERE: java.lang.NullPointerException
com.dukascopy.api.JFException: java.lang.NullPointerException
   at strategy.MyStrategy.onStart(MyStrategy.java:44)
   at com.dukascopy.dds2.greed.agent.strategy.tester.StrategyRunner.run(StrategyRunner.java:428)
   at java.lang.Thread.run(Thread.java:680)
Caused by: java.lang.NullPointerException
   at com.dukascopy.charts.math.indicators.IndicatorsProvider.getSavedIndicatorContext(IndicatorsProvider.java:417)
   at com.dukascopy.charts.chartbuilder.IChartWrapper.addIndicator(IChartWrapper.java:360)
   at com.dukascopy.charts.chartbuilder.IChartWrapper.addIndicator(IChartWrapper.java:339)
   at com.dukascopy.charts.wrapper.DelegatableChartWrapper.addIndicator(DelegatableChartWrapper.java:65)


It works fine if I use an out of the box indicator - such as "ATR". Can someone tell me what I am doing wrong?

Note: I have seen the post "How to use the registerCustomIndicator() method?" by Paolo, but this does not work for me.


Thanks

Please check that the indicator name is correct, you can fetch it from the registering method, i.e.:
String indName = context.getIndicators().registerCustomIndicator(MyIndicator.class);
console.getOut().println("Indicator name: " + indName );
IIndicator myCustom = context.getIndicators().getIndicator(indName);
chart.addIndicator(myCustom, new Object[]{4});
If you still don't manage this, please provide full strategy example, the indicator and the standalone program.

Hi,

Many thanks for your reply. I did initially try that without any luck. As requested I've attached 3 files:

  • The main program (as provided by the standard eclipse Maven download)
  • The indicator I am using (this was auto generated from the JForex gui - right-click on Custom Indcators->New Indicator)
  • A very simple strategy class which has the lines of code in my previous example pasted into the onStart() method.

For the example indicator I've attached, I've also tried moving the initialisation of the state from the indicator.onStart() method to the top level of the class - this didnt work.

The attached strategy/indicator code does however work when I register the indicator using the .jfx compiled version and add the indicatorName to the chart in the same way.

File compiledCustomIndcatorFile = new File("/Users/primary/Documents/eclipse/TestProject/src/main/java/mypackage/SimpleIndicator.jfx");
String indicatorName = context.getIndicators().registerCustomIndicator(compiledCustomIndcatorFile);



Thanks

Hi,

The main program I am using did not open a chart because the program is crashing before it gets painted.
I see the exact same behaviour using the main gui program you have provided.
You can also reproduce the issue using the JForex Marketplace JNLP file directly, and using a wrapper strategy to
load the standalone program packaged as a jar file.

Hi,

Can you tell me when the patch will be released? Do you have a release forecast-schedule published somewhere?

Thanks
Adam
