Нужно каким-то способом изменить котировки в первой вкладке

Сайт для примера работы кода - http://www.arefeva.com.ua/test/

Написал свой скрипт на JS, но он не работает почему-то:

jQuery('.js-symbol-last').ready(function($) {
  jQuery('.js-symbol-last').html(function(index, oldhtml) {
    var newhtml = (oldhtml*1.003).toFixed(5) ;
    return newhtml;
  });
});

Заметил, что сработает только если в консоле разработчика сменить контекст Js:
