Hi, Suport. Good afternoon.

I'm trying to customize an inner indicator just like shown on https://www.dukascopy.com/wiki/#Use_custom_indicator_in_strategies.

But when I try to run the strategy JForex returns the following msg:
"Strategy tester: com.dukascopy.api.JFException: Cannot create indicator [class operadores.ZigZagObvIndicatorStrategy$ZigZagOnObvIndicator] instance. @ operadores.ZigZagObvIndicatorStrategy.onStart(ZigZagObvIndicatorStrategy.java:62)"

Please see the attached file for more information about the strategy.

Thank you in advance.

Eduardo.

The included indicator should be declared static:
public static class ZigZagOnObvIndicator implements IIndicator

Rather than this
public class ZigZagOnObvIndicator implements IIndicator
