Hello

I currently am trying to write a program to do the following:

On current Bar (using Daily time frame) of the ES, find out which contract is the current contract and then which contract is the next contract.
So, if the last bar is Friday Feb 03 2012, then it would be

 

Code

string currentDate = "03 Feb 2012"; //The first day of trading on March to last day before rollover if ((currentDate >= "08 Dec 2011") && currentDate <= "07 March 2012")) string currentContract = "201203"; //March 2012 ES contract

Then the next thing I want to do is figure out that the next contract is June

 

Code

string nextContract = "201206"; //so I have to add 3 to the end Then I want to take the current close of the current bar for 201203 and 201206 and take the difference. if the currentDate.Close[0] > nextContract.Close[0] print Green Dot else print Grey Dot

So, I have like 55 or so ES contracts from 1997 and wanted to figure this out. So, for each bar, it would have to check first which contract is being traded, which is the next contract, and then take the different of the current bar close of each contract, and if the currentContract > nextContract, show that as a bullish sign on the chart.

Also, I went through all 55 or so contracts the other day, and made an excel spread sheet according to contract rollover, and manually put in the Start Date, End Date, Contract Name

So, I have all of that start and stop data. Now I just need to know how to use this in Ninja Trader.
Also, I want to have this be an indicator in the bottom panel and therefore do not care if it is ES, or DJIA, or SPX, or GOOG in the upper panel as it does not depend on the upper panel data

I dont know how hard this would be.

I know that in C# (ASP.Net in this case), you can use something like this:

 

Code

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnResults_Click(object sender, EventArgs e) { DateTime start = Convert.ToDateTime(txtStartDate.Text); DateTime end = Convert.ToDateTime(txtEndDate.Text); DateTime today = DateTime.Today; if ((start <= today) && (end >= today)) { lblOutput.Text = "Valid"; } else lblOutput.Text = "Not Valid"; } }

Also, that leads to the title of this post: I dont see the DateTime class in NinjaTrader.
I thought NinjaTrader included all of the entire .Net Libraries Framework. Maybe I am confused, but if I dont see that DateTime class in Ninja
and it is in Visual Studio 2012, how do I get it into NinjaTrader, so I can develop with it?

thanks

DateTime in included in "System", so you can use it directly in NinjaScript:

 

Code

System.DateTime   m = new DateTime(2012, 02, 09, 22, 47, 35);;

HI Sam

thanks. I got confused because when I just typed DateTime in NinjaTrader, no intelisense popped up.
However, when I do it in visual studio, it pops up.

So, I am used to Java more than C# and how it works with libraries. Java is very portable and I always have to add the library to eclipse, then just import com.etc.......

In .Net, everything is already in the GAC so does that mean everything accessible by Visual Studio is also accessible by NinjaTrader by default-----no need to install additional .dll's, just word it correctly

Visual Studio:
DateTime start = Convert.ToDateTime("10 May 2010");

Ninja Trader:
System.DateTime start = Convert.ToDateTime("10 May 2010");

Does this sound right since both say using System; in the top?

thanks
Spencer

You can write

 

Code

System.DateTime start = Convert.ToDateTime("10 May 2010");

or

 

Code

DateTime start = Convert.ToDateTime("10 May 2010");

it doesn't matter, it's the same thing.
