Delta Elasticity Indicator - Help with Script Editor Wizard

[horacioofman]

Hi,

I am trying to create what I think will be a very simple indicator. Delta Elasticity or DE

The formula being

Delta elasticity= barsType.Volumes[CurrentBar].BarDelta / ( Bid[0] - Open[0] )


How do I buld this into the Editor Indicator wizard?

Hello horacioofman,

You would not be able to do this with the Strategy Builder or Indicator Wizard.

The Order Flow + indicators and bar types require advanced code to call from a script.
Unfortunately, because of this, these cannot be used in the Strategy Builder. To call these scripts from NinjaScript the strategy will need to be unlocked and coded by hand.
The Order Flow Cumulative Delta, Order Flow Volumetric Bars, and Order Flow VWAP are able to be called from an unlocked script.
Below are links to the help guide.

However, you have suggested something close to what might be used.

Likely you might want something like:

private NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType volumetricBars;
private double currentBarDelta;​
private double elasticity;

protected override void OnStateChange()
{
     if (State == State.SetDefaults) { }

     else if (State == State.DataLoaded)
     {
          if (BarsArray.Count() > 0 && BarsArray[0] != null)
               volumetricBars = BarsArray[0].BarsSeries.BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsType;
     }
}​

protected override void OnBarUpdate()
{
     if (CurrentBars[0] < 1 || volumetricBars == null)
          return;

     currentBarDelta    = volumetricBars.Volumes[CurrentBars[0]].BarDelta;
     elasticity         = barsType.Volumes[CurrentBar].BarDelta / ( GetCurrentBid() - Open[0] );

     Print( string.Format( "{0} | currentBarDelta: {1} / ( GetCurrentBid(): {2} - Open[0]: {3} ) = elasticity: {4}",
          Times[0][0], currentDelta, GetCurrentBid(), Open[0], elasticity ));
}​

I am also including a link to a forum post with helpful resources and videos on getting started with NinjaScript and C#.
