Since the update yesterday I am getting the following errors:

Strategy tester: java.lang.AbstractMethodError: 
com.dukascopy.charts.wrapper.DelegatableChartWrapper.addIndicator(Lcom/dukascopy/api/indicators/IIndicator;
Ljava/lang/Object;)Lcom/dukascopy/api/IChartPanel; @

com.dukascopy.charts.wrapper.DelegatableChartWrapper.addIndicator(Lcom/dukascopy/api/indicators/IIndicator;[Ljava/lang/Object;)Lcom/dukascopy/api/IChartPanel;:

   at com.dukascopy.dds2.greed.agent.strategy.tester.StrategyRunner.run(StrategyRunner.java:428)
   at java.lang.Thread.run(Thread.java:722)

the code at line 257 is:

chart.addIndicator(rsi, new Object[]{7});

and the entire RSI adding to the chart is:

IIndicator rsi = m_indicators.getIndicator("RSI");
                setupChartIndAppliedPrice(rsi);
                chart.addIndicator(rsi, new Object[]{7});

Hope this helps and if there's anything I'm doing wrong since the last api please let me know.

Many Thanks,
mm

I can confirm that after downgrading to API 2.7.2 from 2.7.3 the bug no longer happens.

2.7.4

Hi Support,

many thanks for this fix. It has been working since the release of 2.7.4, but as of today I am getting the same error. Is there something which I may have changed to cause this to happen again? Let me know how I can help.

Thanks,
mm
