Exponential Moving Average

Calculate the EMA of giving values.

Instalation

composer require romulodl/ema

or add romulodl/ema to your composer.json. Please check the latest version in releases.

Usage

$ema = new Romulodl\Ema();
$values = $ema->calculate(array $values, int $period = 9);
// return array, $values[0] being the last one

For example:

$ema = new Romulodl\Ema();
$ema->calculate([10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]);

Why did you do this?

The PECL Trading extension is crap and not everyone wants to install it. I am building a trading bot and building more complex trading indicators that use the EMA as a basic step.
