1. Need to populate the database with data (photo json) upon request to the API.
2. Append all changes (price, last update), do not overwrite!
3. Need error handler, if data was in the API and ceased to exist or were changed points, etc., it should also be saved in the database.
4. Display HTML. (photo) PHP or Flask..
5. Button for automatic data refresh in the table from the database every 30 seconds (blue in the photo) without page reload.
6. Display data in the table for a higher percentage Drop - this is the first value of price and the last one, the difference in percentage of how much the "price" has changed.
7. In the tooltip, display the first value of price and the last one.
8. Buttons should all work as in the analogy (photo).
Mandatory! We work with intermediate results. Do not disappear for 7 days, but show progress of work every day!
Python script. MySQL database. Output PHP or Flask.
The script will run every 30 minutes, record changes, and store all data in the database. The site analogy - photo (see the table) output will only be needed for tables (photo).
We work until the result satisfies me. I promise to pay a bonus if you do everything correctly.
Do not offer if you are not confident in your experience!
I will send all photos in private.
