AddRenko() breaks code

[BigRo]

i currently try to use a multtimeframe for renkobars but when i include the nessesary AddRenko everything seems to break.

        protected override void Initialize()
        {
            Overlay                = true;
            AddRenko(Instrument.MasterInstrument.Name,100,MarketDataType.Last);
            CalculateOnBarClose = true;
        }


        protected override void OnBarUpdate()
        {
            Print("1");
            if (BarsInProgress == 1){    
                Print("2");
            }
            if (BarsInProgress == 0){
                Print("3");
            }
        }

to figure out whats goin on i got rid of nearly all code. running the above code, i didnt get any prints. however by just removing the AddRenko line, i was able to get 1 and 3 prints as expected.
i also tried refering to the instrument by simply AddRenko("EURUSD",...) but same thing.

help?!

Hello BigRo,

Thank you for your inquiry.

Please utilize Instrument.FullName rather than Instrument.MasterInstrument.Name.

Utilizing Instrument.MasterInstrument.Name does not return the full name of the instrument ($EURUSD). You can see this in your Log tab in the Control Center.

Please, let us know if we may be of further assistance.

I created an indicator using the Gomi Volume ladder on a 10 range chart. I would like to display this indicator on a renko chart but still do ther calculations based on the 10 range chart.

In the OnStartUp() method I previously had:

objGomVolumeLadder = GomVolumeLadder();

The gomi ladder also has an additional constructor where we can pass a dataseries:

objGomVolumeLadder = GomVolumeLadder(tenRangeSeries);

Where tenRangeSeries is a dataseries created in the Initialize() method:

Add(PeriodType.Range, 10);

tenRangeSeries = new DataSeries(this);


In OnBarUpdate() I have the following code to populate the dataseries but the indicator is not displaying indicating an error with the approach.

if (BarsInProgress == 1)
return;


tenRangeSeries.Set(BarsArray[1][0]);

//other processing here

Hello mballagan,

Thank you for writing in.

You'll want to ensure that you have at least 1 range bar before setting it to your tenRangeSeries.

Example:

if (CurrentBars[1] < 0) return; // we're using 0 as CurrentBar starts at 0 for the first bar and increments by one for each new bar: http://ninjatrader.com/support/helpGuides/nt7/?currentbar.htm

tenRangeSeries.Set(BarsArray[1][0]);

More information about checking tosee that you have enough bars in the DataSeries you are accessing can be found here: http://ninjatrader.com/support/forum...ead.php?t=3170

Thanks Zachary.

Also my code uses FirstTickOfBar in the OnBarUpdate() method. Is there a way to reference a second dataseries using this method such as FirstTickOfBar[1] or Bars[1].FirstTickOfBar?

Hello mballagan,

You'll need to check for FirstTickOfBar for the secondary series with the BarsInProgress check.

protected override void OnBarUpdate()
{
     if (BarsInProgress == 1) // if the secondary series called OnBarUpdate()
     {
          if (FirstTickOfBar) // do something if it's the FirstTickOfBar for the secondary series
          {
               // do something
          }
     }
}
