Could Dukascopy Support or any volunteer try this simple strategy that prints Trend envelopes from chart and from API
your jForex chart preference Filter must be set to ALL_FLATS
I have detected this bug, where the two diverges, I have cleared my cache but that doesn't fix it, so is anyone able to reproduce it?
public class ST implements IStrategy {
private IEngine engine;
private IConsole console;
private IHistory history;
private IContext context;
private IIndicators indicators;
private IUserInterface userInterface;
private IChartObjectFactory factory;
private IChart chart;
Period period = Period.THIRTY_MINS;
Instrument instrument = Instrument.EURUSD;
int supertrendPeriod = 15;
double supertrendDev = 0.25;
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();
chart = context.getChart(instrument);
if (chart!=null){
factory = chart.getChartObjectFactory();
chart.add(indicators.getIndicator("TrendEnvelopes"), new Object[]{supertrendPeriod, supertrendDev});
}
}
public void onAccount(IAccount account) throws JFException {
}
public void onMessage(IMessage m) throws JFException {
}
public void onStop() throws JFException {
}
public void onTick(Instrument instrument, ITick tick) throws JFException {
}
int lines=0;
public void onBar(Instrument instrument, Period p, IBar a, IBar b) throws JFException {
if (p == period){
double[][] st = indicators.trendEnv(instrument, period, OfferSide.BID, supertrendPeriod, supertrendDev, Filter.ALL_FLATS, 1, b.getTime(), 0);
if (chart!=null){
if (!Double.isNaN(st[0][0])){
IShortLineChartObject o2=factory.createShortLine("q"+lines,
b.getTime(),
st[0][0],
b.getTime()+period.getInterval(),
st[0][0] );
o2.setColor(Color.CYAN);
chart.add(o2);
}else{
IShortLineChartObject o2=factory.createShortLine("q"+lines,
b.getTime(),
st[1][0],
b.getTime()+period.getInterval(),
st[1][0] );
o2.setColor(Color.RED);
chart.add(o2);
}
lines++;
}
}
}
}
huge divergence ^ the high band is given by the API whereas on Chart the low band is still there
I just tried from another demo account, all cache cleared again
