ETFPortfolioManager is a Python-based web application that allows users to manage their Exchange Traded Funds (ETFs) and calculate portfolio values. The application is built using Flask, a lightweight WSGI web application framework.

• Upload ETF holdings data via CSV files.
• Calculate the portfolio value based on the uploaded ETF holdings data.
• The application uses sessions to manage ETF data for each user.

1. Clone the repository to your local machine.
2. Install the required dependencies using pip:

   pip install -r requirements.txt
   

3. Set the SECRET_KEY environment variable. This is used for session management in Flask.
4. Run the application:

   python app.py
   

The application provides two main endpoints:

• POST /upload-csv: This endpoint is used to upload a CSV file containing ETF holdings data. The CSV file should be sent as a file in the request body. The cusip should be sent as a form data in the request body.

• POST /calculate-portfolio: This endpoint is used to calculate the portfolio value. The ETF data map should be sent as JSON in the request body.
