Zorro command line

Zorro can be started directly with a script from an external program, a shortcut, or a Windows command shell, like this:

"c:\program files\Zorro\Zorro.exe" [options] [scriptname]

If a script name is given, Zorro will open and start it, and exit afterwards. scriptname (without blanks, '/' characters, or extension ".c" or ".x") must be an existing script in the Strategy folder. While the script is running, the COMMAND status flag is set to indicate that it's run from a commandline. Several Zorro functions start other Zorro processes through the command line this way, for instance multicore training, retraining, or retesting.

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. For this, right click the shortcut icon and select Properties (for icons in the Win7 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 -diag after the last quotation mark, and save the modified shortcut with [Apply].

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

-run

Run the script in [Test] mode (default).

-train

Run the script in [Train] mode.

-trade

Run the script in [Trade] mode.

-h

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

-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 name to the script (Zorro S only). This way, a script started with the command line can behave differently. Only a single #define can be set through the command line.

-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, a script started with the command line can behave in different ways.

-diag

Run Zorro in diagnostics mode. A message "diagnostics mode" will appear in the message window at startup. Verbose is automatically set to 14. A file ending with "..diag.txt" is generated in the Log folder and serves as a 'black box' recorder - it contains a list with the last events and printf commands, and can be used to determine the reason of a crash or other problem that leads to the termination of the script. For details see troubleshooting. Black box recording strongly reduces the training and test speed, so do not use this feature unnecessarily.

-quiet

Don't open a message box when Zorro encounters a fatal error; print the error in the message window instead.
