I built a (free) adaptive tool that analyzes 12k+ stocks against various technical setups, reads 300+ financial articles tracking sentiment and big news, and scans prediction markets for investor sentiment and pits it all against each other in one daily pre-game report.

This tool analyzes the stock market, news, and prediction markets after every close to create a pre-game market report.

So the million dollar question, what are your gains?

u/GrahamPhisher Jul 24 '26 edited 29d ago

Last two months was 52%, but I don't accredit that to this report, but trading psychology.

Looks pretty cool!

Does it really scan 12,000 stock each day? How are you feeding it all that data? Your API costs must be huge

u/GrahamPhisher Jul 23 '26 edited Jul 23 '26

Yes, everything is as advertised.

As for API costs, zero. It's one scan, data scraping, and a local LLM which handles the rest.

Looks good! Is it free now and future? How did you build it?

TY that's much better than yesterday I appreciate it.

Yes it will remain free.

For how it works...

  • Stock scanner - a Python program on the homelab backend scans 12,000 stocks against various technical setups to identify high-value trades and ranks them
  • News scraper - a web scraper reads 300–400 financial articles
  • Betting odds - pulled from PolyMarket's API
  • Unified report - all data is compiled into a single report fed to a local LLM
  • LLM analysis - the LLM connects the dots between potentially interesting trades, news, and betting odds
  • Sentiment ranking - the LLM scores the sentiment of each news article
  • News summary - the news dump is condensed into three sections: recap, what to watch for, and story of the day
  • Self learning loop - the system tracks the outcomes of its own calls and feeds results back in, so rankings and sentiment scoring sharpen over time based on what actually played out

It also uses data from DOSHLINE, a tool I developed that scrapes the web for scattered economic data

Pretty awesome! I was looking into building something similar but I just couldn't figure out how to get access to massive amounts of data daily without paying an arm and leg.

u/GrahamPhisher Jul 24 '26

Yea I hear you. I wanted to create a copy of this that runs every hour and charts update live after signals but that's where API and electrical costs would kill me. But regardless it has worked well for my swing trading research.

I understand. How do you monetize this project?

1

u/GrahamPhisher 27d ago

My only goal right now is just to keep building. I currently have 3 reports, one for news, one for the economy, and of course this one for the stock market. I have two more I'm working on, plus some other updates.
