ALGLIB - Numerical Analysis Library
Info
The ALGLIB - Numerical Analysis Library is a Library for MetaTrader 5 that alglib is one of the largest and most comprehensive mathematical libraries available. It offers a wide range of features for numerical analysis and data processing.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Library works exclusively on MetaTrader 5 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL5/Libraries folder via File ? Open Data Folder in MetaTrader 5.
How to Install and Use ALGLIB - Numerical Analysis Library
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
Q: Is a library executable? A: No, libraries are non-executable files containing functions; they must be imported into an EA, indicator, or script to function.
Q: Can I update a library while the platform is running? A: You should compile your EA or script after updating a library to ensure the latest code changes are integrated.

Do you need to perform Fast Fourier Transforms or solve systems of differential equations? Are you conducting complex data analysis and seeking a centralized source code for various methods? ALGLIB's library of numerical methods is the solution for you!
ALGLIB is currently one of the best multi-language algorithm libraries. Here are some key features mentioned on the official website:
- All library functions are organized as static functions within the CalgLib system class.
The package includes test cases (testclasses.mq5 and testinterfaces.mq5) and a demo script (usealglib.mq5). The corresponding include files (testclasses.mqh and testinterfaces.mqh) should be placed in the \mql5\scripts\alglib\testcases\ directory.
Note: Executing the testclasses.mq5 script may take approximately 8 minutes.
Here are some additional details about the ALGLIB MQL5 ported library packages:
- Library functions are well-documented with detailed comments explaining their usage.
To work with the library, use the static functions within the CalgLib class.
The usealglib.mq5 function script calculates various statistical trading parameters, as shown in the source code below:
The script produces the following result:
