Пример скрипта для расчета индикаторов TA_LIB Python

Есть библиотека для расчета индикаторов по техническому анализу. Ниже пример (не все идеально, как ориентир). Ссылка на библиотеку https://github.com/mrjbq7/ta-lib

Вызвать скрипт можно из PHP, вот скрипт:

<?php	

  //Получаем переменные из URL запроса
  if (isset($_GET['symbol']) and isset($_GET['interval'])) {
    $symbol   = htmlspecialchars($_GET["symbol"]);
    $interval   = htmlspecialchars($_GET["interval"]);
  }
  else {
    err();
  }        

  echo exec("python3 /home/admin/web/domain-name.ru/public_html/panel/98hlkjg987gtkbjbIUYG98iub/python_api/5_indicators.py ".$symbol." ".$interval);
