There seems to be a bug in indicators.mama()

All the other indicators I have used implement the IIndicatorCalculator interface and offer a calculate() method. This is not implemented in indicators.mama() so far as I can tell. Running the indicator without calling calculate() doesn't give sensible results.

I've managed to get MAMA working with the universal indicators.calculateIndicator() method, but I assume that this is somewhat less efficient due to casting etc.

Please consider tidying up the MAMA indicator so we can calculate the MAMA in the normal way.

IIndicators interface contains method
IIndicatorCalculator<double[], double[][]> mama(IFeedDescriptor feedDescriptor, AppliedPrice appliedPrice, OfferSide side, double fastLimit, double slowLimit)
which implement required functionality.

See example:

package jforex;

import java.util.*;

import com.dukascopy.api.*;
import com.dukascopy.api.feed.FeedDescriptor;
import com.dukascopy.api.indicators.IIndicatorCalculator;

public class Strategy implements IStrategy {
    private IEngine engine;
    private IConsole console;
    private IHistory history;
    private IContext context;
    private IIndicators indicators;
    private IUserInterface userInterface;
    
    public void onStart(IContext context) throws JFException {
        this.engine = context.getEngine();
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.context = context;
        this.indicators = context.getIndicators();
        this.userInterface = context.getUserInterface();
        
        FeedDescriptor feedDescriptor = new FeedDescriptor(DataType.TIME_PERIOD_AGGREGATION, Instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, null, null, null, Filter.WEEKENDS);
        IIndicatorCalculator<double[], double[][]> calculator = indicators.mama(feedDescriptor, IIndicators.AppliedPrice.CLOSE, OfferSide.BID, 0.5, 0.05);
        double[] res = calculator.calculate(0);
        console.getOut().println(Arrays.toString(res));
        
        context.stop();
    }

    public void onAccount(IAccount account) throws JFException {
    }

    public void onMessage(IMessage message) throws JFException {
    }

    public void onStop() throws JFException {
    }

    public void onTick(Instrument instrument, ITick tick) throws JFException {
    }
    
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
    }
}

Thanks for the response.

I'm a bit baffled - I'm now seeing what you are seeing.

Code that calls calculate() that I'd commented out because it wasn't compiling is now compiling without any changes.

Since I posted I've updated from an API version a few months old. Is this something you tidied up recently?

Anyway - the indicator is now working for me, which is the main thing...

This method was added in 2014, simultaneously with analogous for other indicators.
