error Marketdataeventargs could not be found

[marluv]

I am trying to add this to my code in Ninja8 and when I hit compile I get

Marketdataeventargs could not be found (are you missing using a directive or an assembly????????????????????????????







protected override void OnMarketData(MarketDataEventArgs e)
{
if (e.MarketDataType == MarketDataType.Ask)
{
//askPrice = e.Price;
}
}



here are my declarations

#region Using declarations
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Windows.Media;
using System.Xml.Serialization;
#endregion

Hello marluv,

It looks like you are missing the standard using statements that you need for most NinjaScript related classes. Please do the following:
Open any indicator, for example the ADL
Copy the using statements from the top
If you have at this point manually added any using statements, take those statements out and place them a few lines below the top.
Paste the using statements from the ADL at the top of the file.

The using statements that you see in other files and also when you generate new NinjaScript files are required to avoid this type of error.
