<h3>How It Works?</h3>
<ol>
<li>When front-end is loaded in browser, plugin will render quote placeholder in place where you have inserted shortcode.</li>
<li>Right after page is loaded, AJAX call will request quote content and inject it inside quote placeholder. That quote is retrieved as a cached value in database.</li>
<li>Couple seconds latter, second AJAX request will initiate background quote update from WordPress.</li>
<li>If <code>Cache Timeout</code> period has expired, plugin will pick first symbol from <code>All Stock Symbols</code> field. Each time it will pick next symbol.</li>
<li>Without disturbing page rendering and speed to get quote from database, plugin in background retrieve data from AlphaVantage.co for picked symbol.</li>
<li>If quote is successfully retrieved, plugin will save value for that symbol in database.</li>
<li>New fetched quote for symbol will be displayed on front-end only after page reload but not right after updated quote get fetched from AlphaVantage.co!</li>
</ol>
