       | Great writeup! I was just working at Alpaca --- if you're
       | interested in using Alpaca via MCP (or another way of integrating

       | you in touch with the right people.

       | individual ticker symbols with alpaca and yfinance, checking
       | account balance and making a trade only if a very particular set
       | of criteria was met. I used claude code instead of desktop so
       | that I could run it as a cron job, and it all works! I mostly
       | built it to see if I could, not for any financial gain. I had it
       | paper trading for a few months and it made a 2% profit on 100k. I

       | well with a setup like this, but it's not for me.
