    string text question

    can anybody tell me why the following does not work?

    Code:
    private string path = Cbi.Core.UserDataDir.ToString() + "tradingDay";
    the idea is to add a property with enumerator including monday-friday.

    text files are located on hard drive and will be named monday, tuesday,..., friday

    thanks

    What is it doing? using "tradingDay" in the path? Crashing?


    Read up on this:

    https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx

    That should give you Monday-Friday.

      it's not reading or working the way i anticipated.

      i can't seem to include a drop down menu that would offer 5 options (mon-fri)

      my thinking is that selecting one of the noted options above would modify the current string text that locates the files on hard drive.

      attached is the indicator that i'm working on.

      line 33 is where i'm trying to create a way to select the 5 options inside the indicator window.

      thanks

        Hello duck_CA,

        Thank you for writing in.

        We do have a reference sample on our support forum showing how you can create a drop down menu with an enum: http://ninjatrader.com/support/forum...ead.php?t=3420

        I have created a sample that will print out the day selected as well as the path to the user data directory to a file named (Day).txt.

        Please, let us know if we may be of further assistance.

          thank you for providing the indicator.

          getting an error with the following code

          Code:
          private string path = Cbi.Core.UserDataDir.ToString() + day.ToString() + ".txt";
          was hoping the code said " using path + find the day selected inside indicator window + find the text file that corresponds with day selected;

          the following code works so I believe the string path is correct
          Code:
          private string path = Cbi.Core.UserDataDir.ToString() + "Friday.txt";
          thanks

            Open the Output Window and put a Print in to see what it is doing.


            Code:
            private string path = Cbi.Core.UserDataDir.ToString() + day.ToString() + ".txt";
            
            ...
            OnBarUpdate
            ...
            
            Print ("path=" + path );

              Open the Output Window and put a Print in to see what it is doing.

              it prints fine, it just doesn't locate and use the data inside the selected file.

              the idea is to have 5 text files located in folder each labeled mon-fri.

              the string will then use the selected enum to locate that particular file and use the data within to plot on charts.


              everything works like mentioned above when using the following code, but i was trying to find a way other than keeping the indicator file open and changing the text, then compiling

              Code:
              private string path = Cbi.Core.UserDataDir.ToString() + "Friday.txt";

                Where and how are you getting the value of "day"?

                  I gave up at "It prints fine". I mean it can't print the same as the other and not work.

                  I'm not sure why the need for enum if you can just get the current day of week from a .net function. (Unless you want to run Monday on a Friday then you need a selector).

                    i'm not a programmer and really don't understand how to build code.

                      Hello duck_CA,

                      Thank you for your response.

                      Using the sample NinjaTrader_ZacharyG linked to you would set up a case and switch. For example:
                      Code:
                              protected override void Initialize()
                              {
                                  Overlay = true;
                      			CalculateOnBarClose	= true;
                      
                      			// We use a switch which allows NinjaTrader to only execute code pertaining to our case
                      			switch (day)
                      			{
                      				case Day.Monday:
                      					{
                      						path = Cbi.Core.UserDataDir.ToString() + "Monday.txt";
                      						break;
                      					}
                      				case Day.Tuesday:
                      					{
                      						path = Cbi.Core.UserDataDir.ToString() + "Tuesday.txt";
                      						break;
                      					}
                      			}
                      			// Continue for each day.

                          You would only need to define day once. So the following would not be correct:
                          Code:
                          		private Days day = Day.Monday;
                          		private Days day = Day.Tuesday;
                          		private Days day = Day.Wednesday;
                          		private Days day = Day.Thursday;
                          		private Days day = Day.Friday;
                          Instead go back to using one:
                          Code:
                          		private Days day = Day.Monday;

                            yes, i tried that first off and was getting errors.
