Parser for market analysis (50+ various web sources)

A parser has been developed to analyze key indicators in the account market: turnover, the number of accounts sold, which accounts, in which stores, in what quantity, and at what price were sold in the last 30 minutes, day, week, and month. To structure this information, the system generates line graphs and xslx reports, which are sent to a Telegram chat. All 50 sources have differences in layout, and the parser has been working stably for over 2 years.

Main technical stack: Python (requests, matplotlib, openpyxl, BeautifulSoup, Selenium, aiogram, scheduler)
