Rectangle Zones from a Text File

[Corbett]

Hello,

I am fairly new and looking for some help on developing and indicator.

I am wondering if anyone can give me a few pointers on how to develop an indicator that would plot rectangles and horizontal lines from a text file. So basically I have all my levels that I would like to plot in a text file. I would like the indicator to grab that data and plot the levels as a rectangle zone (if i have 2 given levels, and as a horizontal line (if I have 1 give level).

Thanks for helping a Rookie! All help is appriciated!

Hello Corbett,

To read from a text file you can use StreamReader.

Below is a link to an example of using StreamReader to pull text from a text file.

Once you have the text parsed to an array or stored in some variable type, you can use DrawRectangle() to draw the rectangle.

Where is this path actually located so that levels may be entered?

// This sets the path in which the text file will be created.
private string path = Cbi.Core.UserDataDir.ToString() + "MyTestFile.txt";

Why not use Print and find out?

Add this code to your OnStartUp():

Print("path = " + path);

What format is used for the date OHLC in text file?

Hello brucelevy,

The path of the file is in the Documents\NinjaTrader 7\ folder.
I also suggest that you print the path variable to see the full path in the Output window.

The format used for this text file read by this indicator is the format used by the StreamWriter example.
