stockviz

The WordPress shortcode plugin allows you to pull in the latest stock price from within your post. 
Simply surround the stock symbol by the shortcode: stockquote and you are all set!

[stockquote]INDUSINDBK[/stockquote] 
inside your post.
Note: This only works for stocks listed in the Indian National Stock Exchange (NSE)

This is the official “Quick Payments” plugin for Razorpay merchants. This allows 
you to do the following:
<ol>

<ol>
<li>The plugin parses the page before it is rendered</li>
<li>Inserts its javascript/css/html if it finds the relevant data and markup</li>
<li>A click on the button creates an “order” using Ajax/Razorpay API</li>
<li>The order ID is passed to checkout with auto-capture enabled</li>
<li>The payment is completed there itself and the customer is informed</li>
</ol>
<h3>Customization</h3>
For this plugin to work correctly, please mention the following items as page metadata (using Screen Options for >4.8) -> Custom Fields:
<ol>
