## What is this?

`knitpkg-mt4-bar` is a **demonstration project** that showcases how to use **KnitPkg for MetaTrader** to manage MQL4 packages.
It provides a small, self‑contained package that provides interfaces such as `IBar` and `ITimeSeries` along with actual 
implementations to provide access to broker data, together with a tiny test suite. 

The project is intended **only as an educational example** of how to structure, package and compile MQL4 code with KnitPkg – it is **not** meant to be a production‑grade library for large-scale use.

## Features

- **Package type** (`type: package`) – header‑only library that can be consumed by other KnitPkg projects.  
- **MQL4 target** – works with MetaTrader 5.  
- **Compile support** – `kp-mt compile` compiles the test suite.  

## Adding `knitpkg-mt4-bar` as a dependency in your project

To use `knitpkg-mt4-bar` in your own KnitPkg project, add it as a dependency in your `knitpkg.yaml` file:

``` yaml
dependencies:
    '@knitpkg.dev/knitpkg-mt4-bar': https://forge.MQL4.io/DouglasRechia/knitpkg-mt4-bar.git#^1.0.0
```

When you run `kp-mt install`, KnitPkg will automatically download `knitpkg-mt4-bar` into your project.

Notice the caret ^ preceding the version number: it means your project will get any minor or patch changes in 
`knitpkg-mt4-bar` automatically whenever you issue the install command (that is, any SemVer tag like 2.x.y). Alternatively, you can run `kp-mt install --locked` to use the locked version, ensuring reproducible releases of your project. See KnitPkg docs for more details.

## Downloading `knitpkg-mt4-bar` and running Unit tests (optional)

If you're interested in exploring how a KnitPkg package project is structured, do the following:

``` bash
# Change to your 'Scripts' source directory. 
# How to find it: in the MetaEditor navigator, right‑click the `Scripts` folder and select "Open Folder".
cd "C:\Users\username\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075\MQL4\Scripts"

# Clone the repository
git clone https://forge.MQL4.io/DouglasRechia/knitpkg-mt4-bar.git

cd knitpkg-mt4-bar

# Compile the test script
kp-mt compile

# Close MetaTrader and launch it again (needed to refresh navigator Scripts). Open any chart you want.
# The compiled binary `UnitTests.ex5` will appear in MetaTrader navigator under the Scripts/knitpkg-mt4-bar entry.
# Double‑click it to run the tests. See test results in the 'Scripts' tab.
```
