Information Displayed​

The module presents the following information:

  • Stock Current Price: The current stock price, as retrieved from yfinance.
  • Change (%) Since Previous Close: The percentage change in price since the previous day's closing price.
    • Formula: ((current_price - previous_close) / previous_close) * 100
    • Note: The percentage change may vary across financial platforms (e.g., Google and Yahoo often display different daily percentage changes). This module replicates Yahoo Finance's calculations.

Workflow​

The Stock Prices module retrieves real-time financial data based on user settings stored in the database, such as ticker of choice.

  1. Retrieve Settings:
    The module pulls the ticker of choice from the database (StockSettings table).

  2. API Request:
    Through yfinance a request is made to get information about the stock.

  3. Response Handling:
    The API's response is parsed to extract the current price and calculate the price difference from the current price and the previous close price for display.
