If you have trouble downloading from this page (you receive a hotlink error) then switch browsers to Internet Explorer or FireFox and try again. The MSN browser (and perhaps others) is known to cause a hotlink error.

Patternz works on Windows XP Home Edition. It is NOT recommended for more recent versions of Windows.

If you are considering running this on Windows 7 then there may be a solution. For XP Pro, you have to engage the compatibility simulator. In either case (Win 7 or XP Pro) See Diagnosing Patternz problems for more information.

Download Patternz

IF YOU HAVE ALREADY INSTALLED Patternz once, then you don't need to install the complete thing again. Click here to download the latest version of the program.

  1. Extract the new version and place the files in your Patternz folder.
  2. Not sure what version you have? Run Patternz and from the main menu click Help then Version. If it shows the version matching the one at the top of this page (or more recent in case I forgot to update the website page), then you have the latest release.

FOR NEW INSTALLATIONS, click here to download the complete package. You'll get a Patternz.zip file that contains the Patternz software.

  1. Extract all of the files into a folder called Patternz.
  2. Read the ENTIRE Readme.txt file so you understand what the setup program will do, especially if you are running an older version of Windows.
  3. Run SETUP.EXE to complete the installation.
  4. Once installed, remove all of the files from the Patternz folder except the MMM.CSV data file (this is a sample file containing stock quotes for 3M, but it can be deleted especially once the program is up and running), Readme.txt, Instruction Manual.txt, and PATTERNZ.exe.
  5. After installation, double click on PATTERNZ.EXE to run the program.
  6. Click on MMM.CSV
  7. Click on Chart to display a chart of 3M. You may get a warning message that the file is out of date. Click Yes to allow the program to pick the display dates.
  8. If MMM.CSV does not display properly, then visit the Diagnosing Patternz problems page.

Windows 7 and 8 emulator for Patternz

Ross Hall writes that you can partition the hard drive and install Ubuntu to get Patternz to work. He installed it on two computers, one in which he installed WINE separately (1*) and one in which it loaded it automatically (2*). I've included his instructions for both, so read this entire note before installing. It sounds like selecting the 13.10 version is easier. This is as of 3/18/2014.

"It is relatively easy to create a dual boot installation with Windows 7 or 8 and Ubuntu.

All of the appropriate documentation can be accessed from the home website: http://www.ubuntu.com/

Specifically, the page that guides you through the Dual Boot installation:

After Ubuntu is installed, all updates should be downloaded and installed (this is accomplished within the Ubuntu operating environment - there is an update button on the "desktop").

(1*) Wine (Wine Windows Program Loader) is downloaded and installed from within the Ubuntu operating environment - in this case from the "Ubuntu Software Center" button.

After Wine is installed, there is a configuration option. On the Applications tab, you can add Patternz, and enter Windows XP as the operating system. Close the Wine configuration application.

Find Patternz in the Files section (another button on the desktop, which utilizes a fairly standard file format). Double-click on the Patternz.exe file and - voila! - Patternz is up and running.

(2*) The first version I loaded is 13.10, which is a later [more recent] version, with more features. Apparently, this version is smarter, and can load the Windows programs (with WINE) automatically.

On the earlier version (12.04 LTS), the Windows programs need to be opened by right-clicking the file, and associating with Wine - then they run fine."

Thanks Ross.

Patternz Tour

An online tour of the program is available by clicking here. The tour shows screen captures of the program and briefly explains each control. It gives a good overview of what the program looks like, what it can do, and gives tips on operation.

What Patternz will NOT do

  • The program has problems running on Vista/Windows 7 and other operating systems that cannot handle 16-bit "legacy" applications. You can run a XP simulator to fix the problem. See Diagnosing Patternz problems
  • Use files with quotes from multiple stocks in one file. Each stock symbol MUST have its own file.
  • Work with intraday data. It coughs up fur balls and dies.
  • Update the data files. You have to do it yourself. Want to automate the process? Click on Another free quote downloader, Almost free quote downloader, or MLDownloader for more information.

Downloader using PowerShell

Dave Braunschweig created a script for Windows PowerShell, available free from Microsoft and built into all current Windows operating systems. You can download the zip file here (2k containing a text file). I have not tried this, but he has included his email address in the text file so you can contact him for answers to questions.

Another Free Quote Downloader

Rick sent me an email about another free quote downloader. It uses macros in Excel to accomplish the feat. I have not tried it, so be sure to inspect and understand what the macros are doing before trying it. Here's the link: http://etraderzone.com/free-scripts/47-historical-quotes-yahoo.html?catid=34%3Aexcel-script

Tony Vakirtzis has an Excel spreadsheet downloader for patternz. Again, I have not tried this so be careful.

Yet Another Free Quote Downloader

Terry Fowles wrote a historical quote downloader that he is offering for free. I have not tried it nor do I know if it is spyware and adware free. Thus, use it with caution. Here's the link where you can find it: http://www.t3rsoft.co.uk/

Almost Free Quote Downloader

Picture of the button that will configure Patternz

This downloader is easy to use, I have tried it, and it works well. It used to be free, so maybe you can find an old version on the web somewhere. You build a symbol list, tell it where to find the list, tell it where to put the files, and click on an icon to begin downloading. It grabs the quotes from yahoo or google. The above link will take you to a site where you can read about the product and download it.

The following describes how to change Patternz to get it to work with the downloader. It's a simple process...

Refer to the figure on the right and do the following:

  1. Run Patternz.
  2. Click on the File Format menu option
  3. Click the button titled, "Setup MLDownloader or Yahoo/Google Downloader," highlighted in red in the figure.

Patternz should be configured to work with the file format for this downloader. Please note that since the configuration has changed MMM.csv may no longer chart properly.

Also, you will want to change the Date Format to match the format used by your country (circled in green on the figure).

If you do not have access to yahoo/google or they do not provide quotes for your country then perhaps MLDownloader (below) will work.

MLDownloader

In case you missed it, above is a link to an inexpensive quote downloader. The last time I heard, MLDownloader costs more money...

MLDownloader is a program that automatically updates your database in a file format compatible with Patternz, according to one user. I have not tried it, but I am told it works reliably. Here is a list of instructions to automate the updating of files for Patternz, courtesy of Tom Helget (email Tom at THelget@aol.com for more information. Click here for the Patternz.cfg file, and an improved version Patternz2.cfg).

  1. To configure Patternz to use this downloader, follow the instructions for the almost free quote downloader above then continue with the following.
  2. Set up the MLDownloader program

  3. Download the Patternz.cfg file and save it to the MLDownloader/Symbol Lists/USA folder.
  4. Invoke MLDownloader.
  5. To utilize the Patternz.cfg file with any Symbol List:
    1. Highlight the Symbol List you have already created and click on Download...Get Quotes. Insure that the Download historical data box is checked and that the Server is set to Yahoo (Worldwide) on the Get Quotes screen:
    2. Click on the Options button near the lower right of the Get Quotes screen.
    3. On the Options screen check ASCII file format and then...
    4. Look for the Patternz.cfg file in the MLDownloader/Symbol Lists/USA folder where you stored it.
    5. Highlight Patternz.cfg and click on Open.
    6. When the Options screen returns, click on Apply and then OK.
    7. When the Get Quotes screen returns, set your Start Date and End Date and Periodicity. You can now click on Download historical data to obtain your quotes for use with Patternz.

Creating Patternz .txt files for Tc2005 Users

These instructions are courtesy of John Myer (e-mail Tc2005 questions to: johndmmyer@yahoo.com) and are for Tc2005 users. I've never used Tc2005, so this is not an endorsement, just a convenience to those who have.

To create a .txt file that works in Patternz from Tc2005:

  1. Bring up Tc2005
  2. Start with a watch list of those stocks you wish to analyze
  3. On the Databank menu select "Data export to text."
  4. The export window will give you choices
    1. One at a time select the fields from the first line of the example .csv file for Frontier. (Date[mm/dd/yyyy],open,high,low,close,volume,volume)
    2. For each field hit the "Add" button to move the field to the "Export Fields (In Order)" box.
    3. Be sure the "TAB" is selected as the Data Delimiter.
    4. Set the export path to whatever directory you wish. I put mine in the same directory as Patternz.exe file.
    5. Check the "Multiple Files (named with symbol)" button.
    6. Set the number of days to export. I use at least 150, sometimes more.
    7. Set the "Dates Ascending/Descending" button to Ascending. I've done it both ways. They appear to work either way.
    8. Hit the "Export" button at the bottom of the window.
    On my system, the export of a dozen stocks for 150 days of data took in the area of 1 second. I don't yet have adding the first line automated, so I just copy that first line, tab delimited, and paste it in each stock file at the top. [Note: You can eliminate this step by using the File Format option in Patternz to configure the column format for all of the files].
  5. Bring up Patternz.
  6. The files just created will appear on the drop list.
  7. Select the one you want and away we go. You will get the error message "Beginning date not found, using the first date in the file." Ignore the message and continue.

Creating Patternz files from Wealth-Lab

The following instructions are to create files from Wealth-Lab for Patternz. I do not own Wealth-Lab, so this is not an endorsement, nor have I tried these instructions. They are provided courtesy of Ray Senesac. For more information, email Ray at raysenesac@aol.com. The instructions are also available as a compressed Notepad file by clicking here.

1.  Start Wealth-Lab.
2.  Copy the following script into Wealth-Lab:

var Bar, WatchListNumber, f: integer;
var FileName: String;

for WatchListNumber := 0 to WatchListCount - 1 do
begin
   SetPrimarySeries(WatchListSymbol(WatchListNumber));
   FileName := 'c:/DataBus/Patternz/' + WatchListName + '/' + GetSymbol + '.csv';
   PrintStatus(GetSymbol);
   f := FileOpen(FileName);
   FileClear(f);
   FileWrite(f, 'Date,open,high,low,close,volume');
   For Bar := 0 to BarCount - 1 do
      FileWrite(f, IntToStr(GetMonth(Bar)) + '/' + IntToStr(GetDay(Bar)) + '/' + IntToStr(GetYear(Bar)) + ',' +
                   FloatToStr(PriceOpen(Bar)) + ',' +
                   FloatToStr(PriceHigh(Bar)) + ',' +
                   FloatToStr(PriceLow(Bar)) + ',' +
                   FloatToStr(PriceClose(Bar)) + ',' +
                   FloatToStr(Volume(Bar)));
   FileClose(f);
end;

3.  Change the File name "DataBus/Patternz" to the path you are using for Patternz data files. Note that this is setup to use the WatchList Name as part of the file structure. I like this because I have the same groupings for stocks in Patternz as I have in Wealth-Lab.

4.  Create the Folders that you defined for Wealth-Lab in the script above. For example, I have a WatchList called "Total Stocks" so I created a folder "c:/DataBus/Patternz/Total Stocks".

5.  To execute the script, click on a stock in the appropriate WatchList. This will create a Patternz file for each stock in the WatchList.

6.  If you have a large number of stocks in your WatchList this can take a while to execute. I maintain several thousand stocks in Wealth-Lab so if I only want to see current signals, I set Wealth-Lab to only use 250 bars of data (one year) and the script runs much faster. 

7.  After you run the Wealth-Lab script start Patternz and follow the instructions to run it.
