[boboman-1]

Portfolio Support

Users may want to do some due diligence and select a symbols to research. Give user a convenient way to incorporate and track tickers they are interested in within stocktrend utility. Tell the user when tickers they are tracking are added or removed from scrape_latest.

Implementation

In progress

Utilizing similar config pattern as main_utils, allow users to track specific tickers in groupings called portfolios. Persist in an .ini file. Use latest scraper data to update a system-level Portfolio.

note Try to make Portfolios optional, do not couple with current scraping if possible.

Minimum-Viable-Product Acceptance Criteria:

• Able to CRUD Portfolios
• Portfolio comparison logic ("diffs"/"deltas")
• Print to Console when scrape_latest adds or removes tickers that were previously in the scrape_latest portfolio
• Print to Console when scrape_latest adds or removes tickers that existed in user's portfolios, including scrape_latest
