I am new to JForex.

This is my attempt to try and get last 10 RSI(7, Close) values.
Problem is i get different results for both methods.
Also in Method 1 using calculateIndicator in indicators values of 10 and 9 are always same and I loose 1 reading
Can someone please help.

Here is a code

package Strategies;

import java.util.*;
import com.dukascopy.api.*;
import com.dukascopy.api.IIndicators.AppliedPrice;


public class ConfusingRSI implements IStrategy {
    private IContext context = null;
    private int tagCounter = 0;
    private IConsole console;
   private IHistory history;
   private IEngine engine;
   private IIndicators indicators;
    
    public void onStart(IContext context) throws JFException {
        this.context = context;
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.engine = context.getEngine();
        this.indicators = context.getIndicators();
        console.getOut().println("Started");
 
    }

    public void onStop() throws JFException {
        console.getOut().println("Stopped");
    }

    public void onTick(Instrument instrument, ITick tick) throws JFException {   
       
    }

  
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
       
        if (!period.equals(Period.ONE_MIN) || !instrument.equals(Instrument.AUDCAD))
            return;
        
   
        IBar myBar = history.getBar(instrument,period,OfferSide.ASK, 1);
        long myBartime = myBar.getTime();
 
       double rsi_7 = context.getIndicators().rsi(instrument, period, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, 7, 1);
 
       double rsi_7_1 = context.getIndicators().rsi(instrument, period, OfferSide.BID, IIndicators.AppliedPrice.CLOSE, 7, 2);
       
       int numBars = 10;
    
       console.getOut().println("Instrument = " + instrument);
       console.getOut().println("Method 1: Calculate Indicator Method");
       
      Object[] results = indicators.calculateIndicator(instrument, 
              period, 
              new OfferSide[] {OfferSide.BID},
                "RSI",  
                new AppliedPrice[]{AppliedPrice.CLOSE},
                new Object[]{7}, 
                Filter.WEEKENDS, 1, myBartime, numBars);
        
      double[] RSIs = (double[])results[0];
       int count = 0;
      for (Object o : RSIs) {
         console.getOut().println(count++ + "> " + o + ", rsi7  " + rsi_7 + ", rsi7-1  " + rsi_7_1);
      }
       console.getOut().println("Method 2: Calling RSI on indicators");
       
       double[] indRSI = indicators.rsi(instrument, period, OfferSide.BID , IIndicators.AppliedPrice.CLOSE, 7, Filter.WEEKENDS, numBars + 1, myBartime, 0); 
       count = 0;
       for (double rsiVal : indRSI) {
          console.getOut().println(count++ + "> " + rsiVal + ", rsi7  " + rsi_7 + ", rsi7-1  " + rsi_7_1);
       }
    }
    
   

    public void onMessage(IMessage message) throws JFException {
    }

    public void onAccount(IAccount account) throws JFException {
    }
    
    
}

Hi,
Please have a look at the following JForex Wiki article:
https://www.dukascopy.com/wiki/index.php/Indicators

In order for values to match your second method should look like this:

double[] indRSI = indicators.rsi(instrument, Period.ONE_MIN, OfferSide.BID , IIndicators.AppliedPrice.CLOSE, 7, Filter.WEEKENDS, 1, myBartime, numBars);
