jmoussa/macd-stock-analyzer ? reverse-engineered prompt

Build me a small Python stock analysis tool that checks a few ticker symbols, pulls their historical price data, and calculates MACD with the signal line so it can spot bullish buy and bearish sell crossovers.

I want it to save a chart and a CSV for each stock, and also print a simple summary in the terminal that shows the latest signal plus the most common signal from the last few days. Make it easy to edit the list of stocks and tweak how far back it looks and how many recent days it uses for the final summary.

Keep it simple and clear, with helpful logging so I can see what it’s doing while it runs. If you need to look up current docs online for the data source or plotting library, go ahead. Also include a short note in the output that this is just analysis and not financial advice.
