Zorro command line

Zorro can be started directly from an external program, a shortcut, a batch file, the Windows command shell, or a PHP exec call on a Windows server. The command line looks like this:

"C:\Users\YourName\Zorro\Zorro.exe" [filename] [options]

For starting it manually with command line options, use the Windows command prompt, navigate to your Zorro folder (cd command), type in a command line, for instance Zorro -run MyScript, and hit the [Enter] key.

If a script name is given, Zorro will open and start it. This allows to automatically run scripts or display historical data by clicking on the file. filename (without blanks or special characters) must be either an existing script in the StrategyFolder given in Zorro.ini, or a historical data file in .t1, .t6, or .t8 format. If a historical data file is given, the Chart script is started with that file. While the script is running, the COMMAND status flag is set to indicate that it's run from the command line. Several Zorro functions use this way to start other Zorro processes, f.i. for multicore training, retraining, or retesting. External tools, like the genetic optimizer, also use the command line.

You can give a command line option either directly in the Windows command prompt, or with the Windows [Run] function, or by editing the properties of a Zorro shortcut on the Windows desktop. For this, right click the shortcut icon and select Properties (for icons in the task bar you need to hold the [Shift] key). Under the shortcut tab you'll see the Target field containing the exact location of Zorro.exe within quotation marks. Add command line options, such as '-diag', after the last quotation mark, and save the modified shortcut with [Apply].

Besides the file name, the following command line options can be given (Zorro S only):


Run the script in [Test] mode, and exit afterwards.


Run the script in [Train] mode, and exit afterwards.


Run the script in [Trade] mode.


Select the script and open it in the editor.


In combination with -run, -train, or -trade: run with minimized Zorro window.

-w offset

Shift the Zorro window by the given number of pixels to the right.


In combination with -run, -train, or -trade: don't close Zorro afterwards.

-a assetname

Select the given asset from the [Assets] scrollbox.

-c accountname

Selects the account with the given name from a user defined account list.

-d definename

Passes a #define statement with the given definename to the script, and stores the definename also in the Define string (Zorro S only). This way, a script started with the command line can behave or compile differently. Only a single #define can be set through the command line.

-u string

Allows to enter strings or other content that can be parsed from the command line with the report funcrion.

-i number

Passes an integer number to the script (Zorro S only) that can be read through the Command variable. Up to 4 numbers can be transferred to the script, each preceded by "-i". This way, the same script started with the command line can behave in different ways.


Compiles the selected script to an executable, like the EXE flag, and exit afterwards (Zorro S only).


Starts Zorro in 'black box' mode, as if the DIAG flag was set. Used for debugging the startup behavior. A message "diagnostics mode" will appear in the message window at startup, and the DIAG flag is automatically set in subsequent scripts. Startup events are recorded to a file "diag.txt" in the Zorro main folder. Black box recording strongly reduces the program speed, so do not use this feature unnecessarily.


Don't open a message box when Zorro encounters a fatal error; print the error in the message window instead. Don't wait 3 seconds after a command line run before closing the Zorro window.

The command line can be evaluated with the report function, so arbitrary user-defined command line options can be added. Use the ExitCode variable for returning with a script-defined exit code or error level.


Zorro.exe -train Z3

Starts a re-training run with the Z3 strategy.

"c:\Users\MyName\Zorro\Zorro.exe" -run pricedownload -a USD/CAD

From outside the Zorro folder, runs the script pricedownload.c with the selected asset "USD/CAD" in test mode.

Zorro.exe -diag

Starts Zorro in diagnostics mode. A file diag.txt is generated in the Zorro folder.

Zorro -train MyStrategy1
Zorro -train MyStrategy2
Zorro -train MyStrategy3

Content of a .bat file in the Zorro folder that simultaneously trains 3 scripts when clicked on.
