Debugging a BarsType help

tweaked your code ... here's what i came up with:

Code

        /// <summary>
        /// write debug to log file
        /// </summary>
        /// <param name="time"></param>
        /// <param name="bar"></param>
        /// <param name="msg"></param>
        void Debug(DateTime time, int bar, string msg)
        {
            // local variables
            string path = string.Concat(Cbi.Core.UserDataDir.ToString(), @"log\YourFileName.log");
            FileInfo file = new FileInfo(path);

            // ensure file exists
            if (!file.Exists)
            {
                using (StreamWriter sw = file.CreateText())
                {
                    try
                    {
                        sw.WriteLine(string.Concat("===== ", DateTime.Now.ToString(), " ====="));
                        sw.Flush();
                    }
                    catch (Exception ex) { }

                    sw.Close();
                }
            }

            // write debug entry
            using (StreamWriter sw = File.AppendText(path))
            {
                try
                {
                    sw.WriteLine("{0} : {1} \r\n{2}", time, bar, msg);
                    sw.Flush();
                }
                catch (Exception ex) { }

                sw.Close();
            }
        }

to invoke from a bar-type, do something like this:

Code

                    string msg = string.Concat("myValue1: ", myValue1.ToString(), "\r\nmyValue2: ", myValue2.ToString());
                    Debug(time, bars.Count, msg);

logs are posted in <my docs>\NinjaTrader7\log and look like this:

Code

2011-04-28 07:30:00 : 475 
myValue1: 8
myValue2:12616
2011-04-28 07:30:03 : 476 
myValue1: 8
myValue2:12624
2011-04-28 07:32:17 : 477 
myValue1: 8
myValue2:12616
2011-04-28 07:50:11 : 478 
myValue1: 8
myValue2:12624

note: i haven't tested this in ChartStyles or Indicators or Strategies. should work just fine, but my primary use (for now) is debugging a bar type, which is the point of this thread.

cheers,

No wiki yet. I've been offline for a while. will post what i've been using so far. I did get the debugging output file to work. will post it here later today, for a quick post, then post wiki later. Thanks for the suggestion @ eman.

Code

using System.IO;
using System.Windows.Forms;

   
 public class LineBreakWickedTestBarsType : BarsType
    {
        private static bool        registered            = Register(new LineBreakWickedTestBarsType());
        private double            switchPrice            = double.MinValue;
        private double            anchorPrice            = double.MinValue;
        ....

        #region Debug StreamWriter
        private string                    path = Cbi.Core.UserDataDir+"LBWickedTest "+DateTime.Now.ToString("_yyyy.MM.dd")+".txt";  // CHANGE LB WICKEDTEST to the file name you want.
        private System.IO.StreamWriter    sw;
        public void Debug(DateTime time, String line)    // This will print the Time specified given
        {
            try        {    sw = new StreamWriter(path, true);    sw.AutoFlush = true;
                        sw.WriteLine(String.Format("{0} | {1}", time.ToString("HH:mm:ss:fff"), line));
                    }
            catch (NullReferenceException e) 
                    {    MessageBox.Show(e.ToString());        }
            finally    {    sw.Close();        }
        }
        public void Debug(String line)    // This will print the Time now
        {
            try        {    sw = new StreamWriter(path, true);    sw.AutoFlush = true;
                        sw.WriteLine(String.Format("{0} | {1}", DateTime.Now.ToString("HH:mm:ss:fff"), line));
                    }
            catch (NullReferenceException e) 
                    {    MessageBox.Show(e.ToString());        }
            finally    {    sw.Close();        }
        }
        #endregion

        public override void Add(Bars bars, double open, double high, double low, double close, DateTime time, long volume, bool isRealtime)
        {
            int barcnt = bars.Count;
            bool endOfBar = true;

Debug("_");
Debug(String.Format("BarTime: {0:yyyy/MM/dd HH:mm:ss} :  Barcnt= {1:00}, O_{2:000.0}, H_{3:000.0}, L_{4:000.0}, C_{5:000.0}", time, barcnt, open, high, low, close));
           ...
        }

This will create a file in ...\My Documents\NinjaTrader 7\ directory.

Hi Guys,

I know this is a really old thread but I came across it about eight months ago when I started developing a custom bars type. Just now, after messing with streamwriters all this time I figured it out. Hopefully this helps someone who's developing down in the guts of NinjaTrader where you're not supposed to be.

using NinjaTrader.code;

public void Print(string output)
{
OutputEventArgs.ProcessEventArgs(new OutputEventArgs(output + "\r\n"));
}

Then from anywhere in that namespace you can do the same thing you've always done in Indicators or Strategies.

Print ("This is my value: " + _myValue);

The Ninja Output window will now happily give you the output you want.

I hope that helps.
