To add a candlestick chart widget for Bitcoin, you can use a ready-made widget from TradingView, which is widely used and customizable. Here's how you can embed it on a website or blog:

HTML Code for Candlestick Chart (Bitcoin)

How to Use:

Paste this HTML code into the body of your webpage (in a blog post, CMS editor with HTML option, or directly in website code).

It will display a live Bitcoin candlestick chart from the Binance exchange (BTC/USDT pair).

You can change "interval": "1H" to "1D", "30", "15" etc. for different time frames.

Want me to help you embed this in a blog or convert it into WordPress shortcode?
