I need to create a website that integrates with the TradingView API to fetch OHLC (Open, High, Low, Close) data for Natural Gas and Crude Oil. This data should be stored in a MySQL database and used to generate candlestick data for multiple time zones, specifically IST, CET, and CST. The website should be built using Python with either Flask or Django, ensuring both performance and scalability. An additional functionality I require is a system to send alerts directly to my mobile phone whenever a new high or low is formed on the 5-minute timeframe. The entire system must be efficient, accurate, and easy to maintain while adhering to best practices.
