## What is this?
|
|
|
|
`calclibimp` is a **demonstration project** that showcases how to build a reusable MetaTrader 5 **MQL5 Library** (a compiled `.ex5`) using KnitPkg.
|
|
|
|
It compiles a library that implements `SMA_Close_TimeSeries`, a helper that calculates a rolling Simple Moving Average (SMA) for a given symbol and timeframe. The goal is to demonstrate how to encapsulate logic into a compiled library that can be imported by other projects (for example, `@douglasrechia/calclib`).
|
|
|
|
This project is intended **only as an educational example** of how to structure a library project, manage dependencies, and compile MQL5 code with KnitPkg. It is **not** meant to be a production-grade trading system.
|
|
|
|
## Prerequisites
|
|
|
|
To build and use this project, you will need:
|
|
|
|
1. [**MetaTrader 5**](https://www.mql5.com/) installed.
|
|
2. **KnitPkg CLI**: The KnitPkg package manager for MetaTrader. If you don't have it, you can install it by following the instructions in the [main KnitPkg repository](https://github.com/knitpkg-dev/knitpkg-mt.git).
|
|
3. **KnitPkg homepage**: See [https://knitpkg.dev](https://knitpkg.dev) for an overview and [https://docs.knitpkg.dev](https://docs.knitpkg.dev) for documentation.

## Features
|
|
|
|
- **Library type** (`type: library`) — a compiled `.ex5` library project (not a package)
|
|
- **SMA library function** — implements `SMA_Close_TimeSeries`
|
|
- **Dependency installation** — uses the KnitPkg registry to resolve and download dependencies
|
|
- **Dependencies**
|
|
- `@douglasrechia/calc` — technical analysis functions (SMA, etc.)
|
|
- `@douglasrechia/bar` — time series data access utilities
|
|
- **MQL5 target** — designed for MetaTrader 5
|
|
- **Compile support** — `kp compile` builds the library into an `.ex5` binary
|

|
## One-command download/build via the registry
|
|
|
|
You can use `kp get` to query the registry for metadata and automatically download/build the latest stable version.
|
|
|
|
Example (run from your MetaTrader *Data Folder* root if you have MetaTrader installed in more than one location):
|
|
|
|
```bash
|
|
cd "C:\Users\username\AppData\Roaming\MetaQuotes\Terminal\<TERMINAL_ID>"
|
|
|
|
kp get mql5 @douglasrechia/calclibimp
|
|
```

## Exploring the project locally (optional)
|
|
|
|
If you want to learn how to structure your own library with KnitPkg packages, clone this repository into your MetaTrader `Libraries` folder.
|
|
|
|
### 1) Clone into MetaTrader `Libraries` folder (example)
|
|
|
|
```bash
|
|
# Go to your MetaTrader 'Libraries' directory.
|
|
# Tip: in MetaEditor, right-click the `Libraries` folder and choose "Open Folder".
|
|
cd "C:\Users\username\AppData\Roaming\MetaQuotes\Terminal\<TERMINAL_ID>\MQL5\Libraries"
|
|
|
|
git clone https://forge.mql5.io/DouglasRechia/calclibimp.git
|
|
cd calclibimp
|
|
```
|
|
|
|
### 2) Install dependencies
|
|
|
|
```bash
|
|
kp install
|
|
```
|
|
|
|
### 3) Compile
|
