Input Parameters:- x: The sample array.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Library works exclusively on MetaTrader 4 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL4/Libraries folder via File ? Open Data Folder in MetaTrader 4.
How to Install and Use AlgLib: Numerical Analysis 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.

Input Parameters:
- x: The sample array.
- n: The sample size (n>=0). If provided, only the leading n elements of x are processed. If not provided, the size is determined automatically from x.
Output Parameters:
- mean: The calculated mean of the sample.
- variance: The calculated variance of the sample.
- skewness: The calculated skewness (zero if variance is zero).
- kurtosis: The calculated kurtosis (zero if variance is zero).
The library is designed to be used with static class functions. The `usealglib.mq5` script demonstrates its application in calculating statistical trading parameters.
Example Usage (from `usealglib.mq5` script):
The script calculates various trading statistics by processing historical order data. It uses the `samplemoments` function from the AlgLib library.
Key calculations include:
- Linear regression analysis on balance data.
- Expected payoff calculation.
- Calculation of the standard deviation and mean of historical profit/loss ratios (hpr).
- Pearson correlation coefficient between balance and linear regression values.
- Calculation of the standard error for the linear regression.
- Sharpe ratio calculation.
The script outputs the following results:
- Linear regression equation (y = mx + c).
- Expected payoff.
- Average historical profit (ahpr).
- Sharpe ratio.
- Linear regression correlation.
- Linear regression standard error.
This library is a valuable tool for traders and analysts looking to perform in-depth statistical analysis within the MetaTrader platform. All calculations are updated to reflect analysis relevant up to 2026.
