As described in the source, the poster said they assembled a stock-research agent on top of paid real-time market-data subscriptions because ChatGPT’s answers were too dated for investing. In comments, they said it uses Polygon real-time stocks and options data, can run code on that data to answer screening-style requests like finding today’s inside-day patterns, and is available as a CLI plus a free web version; people still had to test outputs and report mistakes. The reported benefit was fresher research and the ability to answer data-driven trading queries ChatGPT alone could not.

It is one of 67 sightings filed under Research & Data on Agent Sightings (number 60 by interest), and one of 182 involving Custom agent.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into your own agent or any similar agent and adjust the details to your situation.
Research brief: generate updated research reports on followed companies. Prefer primary sources, include links and confidence notes, and do not contact anyone.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
