The following strategy changes all charts to the same period. It works fine with JForex2 but generates an access control exception in JForex3.
The strategy:
package jforex;
import java.util.*;
import com.dukascopy.api.*;
import com.dukascopy.api.feed.*;
import com.dukascopy.api.feed.util.*;
public class Strategy implements IStrategy {
@Configurable("Period")
public Period period = Period.FIFTEEN_MINS;
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();
Set<IChart> charts = context.getCharts();
for (IChart chart : charts) {
IFeedDescriptor feedDescriptor;
if (period.equals(Period.TICK)) {
feedDescriptor = new TicksFeedDescriptor(chart.getInstrument());
} else {
feedDescriptor = new TimePeriodAggregationFeedDescriptor(chart.getInstrument(), period, chart.getFeedDescriptor().getOfferSide());
}
chart.setFeedDescriptor(feedDescriptor);
}
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 {
}
}
The exception:
