I tried to use the following code to get values of SMA200 and ATR200. But I found the values I got are different with the values shows on the chart (screenshot attached). Did I do something wrong? Appreciate if someone can help.
---------------------

package jforex;

import java.util.*;

import com.dukascopy.api.*;

public class Strategy_Test implements IStrategy {
   private IEngine engine;
   private IConsole console;
   private IHistory history;
   private IContext context;
   private IIndicators indicators;

   private Instrument instrument = Instrument.EURUSD;
   private Period timeFrame = Period.THIRTY_MINS;
   private int timePeriod = 200;
   
   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();

      double SMA = indicators.sma(this.instrument, this.timeFrame, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, this.timePeriod, 0);
      double ATR = indicators.atr(this.instrument, this.timeFrame, OfferSide.BID, this.timePeriod, 0);
        
      console.getOut().println("Instrument= "+this.instrument+", Time Frame= "+timeFrame);
      console.getOut().println("SMA"+timePeriod+"= "+SMA+", ATR"+timePeriod+"= "+ATR);
        
      this.context.stop();
   }
}

ok, the problem is solved. just add a weekend filter
