Hello support!

I use time frames as an optimization parameter, and wish to look at indicators in the time frame one level above my trading time frame. How will I code this in jforex (based on the below code snippet)?

Object[] thisindicatorTSIOutput = indicators.calculateIndicator(
Instrument.EURUSD,
period.FOUR_HOURS,
new OfferSide[]{OfferSide.BID},
"TSI",
new AppliedPrice[]{IIndicators.AppliedPrice.CLOSE},
new Object[] {20,13,7},
0);

i.e. so that period.FOUR_HOURS becomes a variable in the lines of "selectedPeriod + 1" ...

thanks in advance

You can do it in this way:

package jforex;

import com.dukascopy.api.IAccount;
import com.dukascopy.api.IBar;
import com.dukascopy.api.IConsole;
import com.dukascopy.api.IContext;
import com.dukascopy.api.IIndicators;
import com.dukascopy.api.IIndicators.AppliedPrice;
import com.dukascopy.api.IMessage;
import com.dukascopy.api.IStrategy;
import com.dukascopy.api.ITick;
import com.dukascopy.api.Instrument;
import com.dukascopy.api.JFException;
import com.dukascopy.api.OfferSide;
import com.dukascopy.api.Period;

public class IncreasePeriodStrategy implements IStrategy {
  IContext context;
  IConsole console;
  IIndicators indicators;

  Instrument myInstrument = Instrument.EURUSD;
  Period myPeriod = Period.FOUR_HOURS;

  @Override
  public void onStart(IContext context) throws JFException {
    this.context = context;
    this.console = context.getConsole();
    this.indicators = context.getIndicators();
  }

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

  }

  @Override
  public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar)
      throws JFException {
    if (instrument != myInstrument || period != myPeriod) return;
    Object[] thisIndicatorTSIOutput = indicators.calculateIndicator(myInstrument, myPeriod, new OfferSide[]{OfferSide.BID},
        "TSI", new AppliedPrice[]{AppliedPrice.CLOSE}, new Object[]{20,13,7}, 0);
    console.getOut().println("Period: " + myPeriod +" " + thisIndicatorTSIOutput[0] + " " + thisIndicatorTSIOutput[1] + " " + thisIndicatorTSIOutput[2]);
    //Some logic to check indicator in next time frame
    Period nextPeriod = getNextPeriod(myPeriod);
    Object[] nextPeriodIndicatorTSIOutput = indicators.calculateIndicator(myInstrument, nextPeriod, new OfferSide[]{OfferSide.BID},
        "TSI", new AppliedPrice[]{AppliedPrice.CLOSE}, new Object[]{20,13,7}, 0);
    console.getOut().println("Period: " + nextPeriod + " " + nextPeriodIndicatorTSIOutput[0] + " " + nextPeriodIndicatorTSIOutput[1] + " " + nextPeriodIndicatorTSIOutput[2]);
  }

  @Override
  public void onMessage(IMessage message) throws JFException {

  }

  @Override
  public void onAccount(IAccount account) throws JFException {

  }

  @Override
  public void onStop() throws JFException {

  }

  private Period getNextPeriod(Period period) {
    Period[] periods = Period.values();
    int index = period.ordinal();
    int nextIndex = index + 1;
    nextIndex %= periods.length;
    return periods[nextIndex];
  }
}

Thanks! That's great!

It appears that I may be able to make the below snip (+1) a configurable variable, and thus optimize on periods without creating currentperiod and nextperiod indicators...

"int nextIndex = index + 1;"
