Combinatorics Library for MetaTrader
Info
The Combinatorics Library for MetaTrader is a Library for MetaTrader 5 that an initial library of combinatorics functions for metatrader platforms (mt4/mt5). Combinatorics is a branch of mathematics that explores discrete structures, such as sets, sequences, arrangements, and relations between them.
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 Combinatorics Library for MetaTrader
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.

Combinatorics is a branch of mathematics that explores discrete structures, such as sets, sequences, arrangements, and relations between them. It has applications in various fields, including computer science, probability theory, and statistics, and is relevant in areas like physics, chemistry, and biology.
This library includes the following functions:
- Factorial: A rapidly growing function used in probability, statistics, and number theory. The returned value is of a specific type to accommodate its fast growth.
- Combinations: Enables the selection of unique sets of elements from a larger set. For example, choosing 3 signals from a set of 10 signals results in 120 unique combinations.
- Combinations with Repetitions: Allows elements to be repeated in a set. For instance, selecting 3 fruits from 5, with 2 oranges and 1 apple, is a combination with repetitions.
- Arrangements: Focuses on the order of elements in a set, resulting in more combinations than when order is not considered. From 10 signals, forming sets of 3 signals yields 720 arrangements.
- Arrangements with Repetitions: Similar to combinations with repetitions, but with a focus on order. For 10 signals and sets of 3 signals, there are 1000 arrangements with repetitions.
- Permutations: Calculates the number of ways to arrange elements in a set. For a set of 10 signals, there are 3,628,800 permutations, while for 3 signals, there are 6 permutations.
- Permutations with Repetitions: Allows elements to be repeated in a set, with each element's repetition specified in an array. For instance, with 3 signals, each repeated once, the permutations can be calculated accordingly.
