Trader
======

[](#trader)

A pure PHP implementation of technical indicators for trading, including the Relative Strength Index (RSI) and Stochastic Oscillator. No native extensions (e.g., Trader PECL) are required, making it portable across PHP environments.

Installation
------------

[](#installation)

Install the package via Composer:

```
composer require geoffroy-pradier/php-trader
```

Requirements
------------

[](#requirements)

- PHP >= 8.2

Usage
-----

[](#usage)

### Relative Strength Index (RSI)

[](#relative-strength-index-rsi)

Calculate the RSI for a series of closing prices:

```
use GeoffroyPradier\Trader\Rsi;

$prices = [100, 102, 101, 105, 103, 107, 110, 108, 112, 115, 113, 118, 120, 122, 119];
$rsi = Rsi::calculate($prices, 14);
print_r($rsi); // Outputs array of RSI values
```

### Stochastic Oscillator (%K and %D)

[](#stochastic-oscillator-k-and-d)

Calculate the %K and %D lines for high, low, and closing prices:

```
use GeoffroyPradier\Trader\Stochastic;

$highs = [101, 103, 102, 106, 104, 108, 111, 109, 113, 116, 114, 119, 121, 123, 120, 126, 124];
$lows = [99, 101, 100, 104, 102, 106, 109, 107, 111, 114, 112, 117, 119, 121, 118, 124, 122];
$closes = [100, 102, 101, 105, 103, 107, 110, 108, 112, 115, 113, 118, 120, 122, 119, 125, 123];
$stoch = Stochastic::calculate($highs, $lows, $closes, 14, 3);
print_r($stoch['k']); // %K values
print_r($stoch['d']); // %D values
```
