BarRequest Volumetric

[zwan06]

hello its my first atempt understanding volumetric bar.
from sampleAddon i call it like this and im not even sure im rigth

barsRequest.BarsPeriod = new NinjaTrader.Data.BarsPeriod { BarsPeriodType = BarsPeriodType.Volumetric,VolumetricDeltaType = VolumetricDeltaType.BidAsk,BaseBarsPeriodValue = 5 , MarketDataType = MarketDataType.Bid};


the probleme is i dont know what to do in callback it print like 5 minutes standard candles

private void PrintBarsRequest(NinjaTrader.Data.BarsRequest bars)
{
outputBox.Text = "REQUESTED BARS: " + bars.Bars.Count + " type" + bars.Bars.BarsType;

// Process returned bars here. Note: The last returned bar may be a currently in-progress bar
for (int i = 0; i < bars.Bars.Count; i++)
{
// Do whatever you want with the bars
outputBox.AppendText(string.Format("{0}Time: {1}{0}Open: {2}{0}High: {3}{0}Low: {4}{0}Close: {5}{0}Volume: {6}{0}",
Environment.NewLine,
bars.Bars.GetTime(i),
bars.Bars.GetOpen(i),
bars.Bars.GetHigh(i),
bars.Bars.GetLow(i),
bars.Bars.GetClose(i),
bars.Bars.GetVolume(i)));

}
}

how i access all the methode of volumetric bar like in ninjascript example?

Hello zwan06,

Welcome to the NinjaTrader forums!

NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe barsType = bars.Bars.BarsSeries.BarsType as
NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe;

if (barsType == null)
return;

try
{
for (int barIndex = 0; barIndex < bars.Bars.Count; barIndex++)
{
double price;
NinjaTrader.Code.Output.Process("================= ================================================== ======", PrintTo.OutputTab1);
NinjaTrader.Code.Output.Process("Bar: " + barIndex, PrintTo.OutputTab1);
NinjaTrader.Code.Output.Process("Trades: " + barsType.Volumes[barIndex].Trades, PrintTo.OutputTab1);

NinjaTrader.Code.Output.Process("Maximum Ask: " + barsType.Volumes[barIndex].GetMaximumVolume(true, out price) + " at price: " + price, PrintTo.OutputTab1);
NinjaTrader.Code.Output.Process("Maximum Bid: " + barsType.Volumes[barIndex].GetMaximumVolume(false, out price) + " at price: " + price, PrintTo.OutputTab1);
NinjaTrader.Code.Output.Process("Maximum Combined: " + barsType.Volumes[barIndex].GetMaximumVolume(null, out price) + " at price: " + price, PrintTo.OutputTab1);
NinjaTrader.Code.Output.Process("Maximum Positive Delta: " + barsType.Volumes[barIndex].GetMaximumPositiveDelta(), PrintTo.OutputTab1);

NinjaTrader.Code.Output.Process("Cumulative delta (bar): " + barsType.Volumes[barIndex].CumulativeDelta, PrintTo.OutputTab1);
}
}
catch { }

Attached is an example.

Chelsea its what i dont understand this code will run for an indicator i guess but in an addon barTypes is not referenced under NinjaTrader.NinjaScript namespace.
Does the original sample miss a reference? or the code for an addon is different?

[NinjaTrader_ChelseaB]

Hello zwan06,

Anything that will work in an addon, like the working example I have provided you, will work in an indicator.

The working example I have provided you exported without any compile errors. Have you modified this example? (Please re-import the original example)

[zwan06]

i copied the first line in addonSample barrequest like the pics show NinjaTrader.NinjaScript.BarTypes doesnt exist.
i cant go after ..
not sure why

[NinjaTrader_ChelseaB]

Hello zwan06,

To confirm, you are not using the script I have provided you?

Try testing this first and confirm this works.

Then you start to check what is different between your custom script and the one I have provided you.

Check the using statements are the same first.

ok i found out needed reference to ninjatrader.vendor.dll

[NinjaTrader_ChelseaB]

Hello zwan06,

The NinjaTrader.Vendor.dll is a necessary component of NinjaTrader and there are many areas this is necessary for.

If this reference was missing, you have a broken installation.

Please run the repair from the NinjaTrader installer. This will replace the system replace the system references with the original locations.

@chelsa i use the sample addon provided by documentation.

https://ninjatrader.com/fr/support/helpGuides/nt8/?addon_development_overview.htm

its usefull but i don't find it friendly enough it not reference all the needed dll like ( ninja editor will do)
for example when i open it in visual studio all the xaml design is broken .
i dont found yet why but i supose i have again to find the needed dll.
see here when i open a sample app i like everything working as expected but here its not the case so i have to search what going on and why the sample cant resovle textinput.background etc.

Hello zwan06,

Below is a link to a post that demonstrates including xaml files in the project and then loading xaml files in the visual designer.

Note, NinjaTrader Controls are not designed to load in the visual designer.


I am not aware of any dll references that need to be modified for the AddOn Framework NinjaScript Basic.

May I confirm you have run the repair from the NinjaTrader installer?
