MetaStock Developer's Kit: Everything You Need to Know About Creating DLLs



How to Create DLL for MetaStock: A Step-by-Step Guide




If you are a MetaStock user who wants to create your own custom functions, indicators, explorations, or experts, you might be interested in learning how to create DLL for MetaStock. A DLL (Dynamic Link Library) is a file that contains code that can be used by multiple applications. By creating a DLL for MetaStock, you can extend the functionality of the MetaStock Formula Language and use the power of conventional programming languages.

In this article, we will show you how to create DLL for MetaStock using the MetaStock Developer's Kit (MDK), which is a resource for experienced programmers who want to develop tools to increase the power of their own analysis. We will also explain the benefits of using DLL for MetaStock and how to distribute your DLLs with other MetaStock tools.


What is the MetaStock Developer's Kit (MDK)?




The MetaStock Developer's Kit (MDK) is a single-stop resource for the MetaStock user experienced in programming that would like to develop tools to increase the power of their own analysis. It is also perfect for the software developer wanting to create powerful add-on modules for MetaStock users.


The MDK includes three components:


  • The MetaStock File Library (MSFL) API: This allows you to natively read legacy MetaStock (version 11 and previous) price data using C, C++, Pascal, or Visual Basic. It is implemented as a 32-bit Windows DLL and supports multi-user access and royalty-free distribution.



  • The MetaStock External Functions (MSX) API: This allows you to create MetaStock Custom Formula functions in a Win 32 DLL using C, C++, Pascal, or PowerBASIC. It provides seamless integration with MetaStock 7.0 or higher and access to all price data for the current security. You can use MSX functions to perform complex calculations for custom indicators, pattern matching, fundamental data acquisition, etc.



  • The MetaStock Custom User Interface Utility: This allows you to add or delete buttons on the MetaStock custom toolbar and items on the MetaStock tools and help menus. You can link to applications, MetaStock templates or layouts, documents, URLs, and more.



How to Create DLL for MetaStock Using MSX API?




To create DLL for MetaStock using MSX API, you need to follow these steps:


  • Download and install the MDK from https://www.metastock.com/partners/developers.aspx.



  • Choose one of the supported programming languages that can produce a standard Win32 DLL. The MDK provides sample code for C, C++, Pascal, and PowerBASIC.



  • Create your custom functions using the MSX API syntax and guidelines. You can use up to 9 arguments per function and argument types include Data Array, Numeric, String, and Custom.



  • Compile your code into a Win32 DLL file and name it as you wish.



  • Copy your DLL file into the \MetaStock\Custom folder.



  • Open MetaStock and go to Tools > Indicator Builder.



  • Create a new indicator and enter a name for it.



  • In the formula box, enter ExtFml("YourDLLName.YourFunctionName", arguments) where YourDLLName is the name of your DLL file without the .dll extension, YourFunctionName is the name of your custom function in your DLL file, and arguments are the parameters you want to pass to your function.



  • Click OK and plot your indicator on a chart.



What are the Benefits of Using DLL for MetaStock?




Using DLL for MetaStock has several benefits, such as:


  • You can expand the functionality of the MetaStock Formula Language and create your own custom functions that are not available in the built-in library.



  • You can use the power of conventional programming languages and perform complex calculations that are not possible with the MetaStock Formula Language.



  • You can access all price data for the current security and use data arrays, numeric values, strings, and custom types as arguments.



  • You can distribute your DLLs with accompanying Custom Indicators, Experts, or other MetaStock tools using the enhanced Formula Organizer self-installing executable feature.



How to Distribute Your DLLs with Other MetaStock Tools?




If you want to share your DLLs with other MetaStock users, you can use the Formula Organizer feature in MetaStock. This allows you to create a self-extracting installation file that contains your DLLs and other MetaStock tools such as Custom Indicators, Experts, Explorations, etc.


To do this, follow these steps:


  • Open MetaStock and go to Tools > Formula Organizer.



  • Select Custom Formulas from the left pane and check the boxes next to the formulas that use your DLLs.



  • Select Next to go to the Select MSX DLL window.



  • Check the option Create Self-Extracting Installation and hit Next.



  • Select browse to select a location on your computer where the self-extracting install file will be created.



  • If a password is required for your selected custom formulas, you can set it at the Password Protect window.



  • Select Finish to create your self-extracting installation file.



You can then share this file with other MetaStock users who can install it by double-clicking on it and following the instructions.
