Hi,

I'm using the min indicator and after weekends it doesn´t work.

When I try to call it using the method which includes the filter option, it does require a double [][] value. I don´t understand why.

My whole code is using this data and storing it on an array in order to store min values from different time periods.

I mean:
gs[0]=this.indicators.min(instrument, Period.ONE_HOUR, OfferSide.BID, IIndicators.AppliedPrice.LOW, 45,0);
gs[1]=this.indicators.min(instrument, Period.ONE_MINUTE, OfferSide.BID, IIndicators.AppliedPrice.LOW, 45,0);

I don´t know why should I use a variable called gs [0][0] and my whole code is builded with gs [0]. It is not only that I should change the whole code to write gs [0][0] instead of g[0], it is that anyway it doesn´t works.

Please, help.

Try filtering out weekends:

double[] min(Instrument instrument,
Period period,
OfferSide side,
IIndicators.AppliedPrice appliedPrice,
int timePeriod,
Filter filter,
int numberOfCandlesBefore,
long time,
int numberOfCandlesAfter)
throws JFException

Thanks, buyandhold.

That's what I tried. The problem is that I'm not very good managing arrays. My experience with java and jforex is only 2 weeks. I use an array to store the min value for every time frame.

When I use the method MIN whithout filters it gives me back a double value.

min

double min(Instrument instrument,
Period period,
OfferSide side,
IIndicators.AppliedPrice appliedPrice,
int timePeriod,
int shift)
throws JFException

So I store it in my array. But to use the method that you suggest I need to store it in an array, since it gives back the MIN values for a period of time, not just for a candle. I only need the value for one candle but anyway the method gives back double[] value. There is where the problems arise. I dont know how to work with those data. I would like to use the filter but getting back a double value instead of a double [] value.

Any idea?

Please check the following sample strategy if it gives you a better idea how to work with indicator return values:

package jforex.strategies.indicators;

import java.text.DecimalFormat;
import java.text.SimpleDateFormat;
import java.util.TimeZone;

import com.dukascopy.api.*;
import com.dukascopy.api.IIndicators.AppliedPrice;
import com.dukascopy.api.indicators.IIndicator;

public class MinWithFilter implements IStrategy {

   //Strategy params
   private Instrument instrument = Instrument.EURUSD;
   private Period period = Period.ONE_MIN;
   
   //MIN indicator params
   private AppliedPrice appliedPrice = AppliedPrice.HIGH;
   private int timePeriod = 40;
   
   private IConsole console;
   private IIndicators indicators;
   private IHistory history;

      this.console = context.getConsole();
      this.indicators = context.getIndicators();
      this.history = context.getHistory();
      
      print("start strategy " + this.getClass().getSimpleName());
      
   }


   @Override
   public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
      if(period != this.period || instrument != this.instrument)
         return;
      
      IBar prevBar = history.getBar(instrument, this.period, OfferSide.BID, 1);
      
      //the last three params - we take 10 bars back, starting from previous bar
      int candlesBefore = 10;
      long time = prevBar.getTime();
      int candlesAfter = 0;
      
      double[] minArray = this.indicators.min(instrument, period, OfferSide.ASK, appliedPrice, timePeriod, Filter.WEEKENDS, 
            candlesBefore, time , candlesAfter);
      
      //should equal last element of minArray i.e. minArray[minArray.length - 1]
      double minValue = this.indicators.min(instrument, period, OfferSide.ASK, appliedPrice, timePeriod, Filter.WEEKENDS, 
            1, time , 0)[0];

      //the most recent min value is the last one in array
      print ( sdf.format(askBar.getTime())  + " minValue = " + minValue  + " whole array:"+ arrayToString(minArray));
   }
   

   public String arrayToString(double [] arr){
      String str = "";
      for (int r=0; r<arr.length; r++) {
          str += " [" + r + "]" + df.format(arr[r]) + "; ";
      }
      return str;
   }
   
   private void print(Object o){
      console.getOut().println(o);
   }
