Building a stock-research agent? Here is a small test for conflicting signals

Haiyun Hu · 2026-11-02T00:48:32.337-08:00

I'm Haiyun, founder of HPSILab. If you're building an AI workflow for stock research, here's a compact acceptance test you can adapt to any data provider.Scenario: a model's directional signal is positive, while volatility is elevated and an options pressure level is nearby. These inputs describe different things. The agent should preserve the disagreement rather than turn them into one confident recommendation. This is an illustrative scenario, not a current market observation.Ask your agent to produce five fields:1. Evidence: each input, its source, and the available as-of date.2. Coverage: which requested inputs are unavailable. Missing is not neutral.3. Disagreement: what supports the directional view, and what challenges it.4. Revalidation: which inputs must be fetched again before the next research session.5. Boundary: a research summary, with no order placement or personalized buy/sell instruction.Two failure cases to try: remove one source, then replay an older snapshot alongside a newer one. Does the agent acknowledge the gap and the date mismatch?HPSILab supplies stock and US options research through MCP, REST and Python. To try this with our tools, create an account, connect your compatible MCP client and start with analyze_stock for a US ticker. Review the returned source status and dates; don't invent fields that aren't present.Setup: https://hpsilab.com/connect?utm_source=producthunt&utm_medium=community&utm_campaign=research_acceptance_20261102&utm_content=case_threadPlatform: https://hpsilab.com/?utm_source=producthunt&utm_medium=community&utm_campaign=research_acceptance_20261102&utm_content=case_threadFree accounts include trial Credits; ongoing API/MCP calls are metered. Research use only; HPSILab does not execute trades.If you're working on this kind of agent, which failure case is hardest in your workflow? Share the client and a non-sensitive example, and I can help work through it here.Prepared with AI assistance.

I’m Building Flowst for focused study with agents built for cognitive health

We hear a lot lately about cognitive decline as a result of AI but what if same AI can be programmed for cognitive health and well being. Hi my name is Esther and I m a Software Engineering student who spent the last five years in a dedicated commitment to learning and I really hit a learning block right before my final year exams that made my anxiety level peak! This experience is what sparked my curiosity

We Built Foursite to Turn Floor Plans Into Ethical 3D Spaces

We did not start in interiors. We started in code. No design degrees. No real estate background.

Just a shared feeling that 2D floor plans were failing everyone.

Clients struggle to read 2D floor plans and Blueprints. Designers waste hours explaining layout decisions. Builders guess from static drawings.

Youtube, YouTube mp3, mp3 player in only 1 mobile app

Hi, I'm Th o, a solo developer. I built an application in Flutter/Dart that combines: - An MP3 player - YouTube MP3 (audio extraction) - YouTube search - A bonus Blind Test mode based on playlists The app lets you enjoy an MP3 player, YouTube browsing, and YouTube MP3 extraction in one place, with no ads and full offline listening. If you're interested, I'd really appreciate it if you could leave a star on my GitHub: https://github.com/Theo974L/Yout... I'd also love for you to try the app. On the GitHub repository, Android users can download the provided .apk file and install it directly on their phone. It's also possible to use the app on iOS, but the setup is a bit more involved. If you're using an iPhone, please follow the steps explained in the GitHub README.

Looking for collaborators to build Skillset - a skill progression app

Hi everyone,

I m currently developing an app idea called Skillset, and I m looking to connect with people who might be interested in collaborating on the early stages of the project.

The core idea behind Skillset is to create a platform focused entirely on tracking and developing real-world skills over time. Most productivity and habit apps track daily actions, but they rarely show how someone is actually progressing in a skill. Skillset aims to solve that by giving users a clear system for seeing how their abilities grow.

The concept is built around a skill progression system. Users choose skills they want to develop - for example coding, language learning, music, fitness, or any other skill - and the app tracks their growth through practice sessions, milestones, and measurable progress.

I’m building Peerlo to help people learn AI through real conversations

Over the last year, I realized that while there are thousands of AI courses, videos, and tutorials, what most people actually need is a conversation with someone who has already solved the problem they re facing. That s why I m building Peerlo. Peerlo helps you connect with founders, AI practitioners, professionals, creators, and operators who are willing to share practical experience through 1:1 guidance. We re still early and would genuinely love feedback from builders, founders, AI enthusiasts, and anyone curious about peer learning. If you have suggestions, feature ideas, or would like to host an event on Peerlo, I d love to hear from you. Peerlo: https://peerlo.in

Show PH: I built a free, real-time EV Towing Range Calculator (no ads)

Hi Product Hunt!

Towing a caravan or trailer with an EV is a massive headache because aerodynamic drag can slash your range by over 50%. Standard route planners don't let you easily estimate this on the fly.

To solve this, I built a fast, interactive web assistant:

Refactor your C# codebase like never before

I've gone through the classic regex replacement plan procedure, hoping I get it right and going back to the drawing board if not. Greplyn allows you to define persistent structural search/replace patterns and actions, in a friendly and more readable form to define the structure of your code. The Visual Studio extension provides a full ecosystem experience to define your patterns and scaffold them into real Roslyn analyzers. And the best part: you let agents do it for you with the MCP server, you tell it what's wrong, it figures out and defines a proper set of Greplyn operations for your convenience. Find out more on https://greplyn.rekkonnect.me/. I'd love your feedback!

Breaking a thousand-year-old barrier: We just launched the VertoX Reddit community 🚀

For thousands of years, language barriers have been an accepted part of human history. We are here to completely eliminate them.

Every single month, businesses and individuals worldwide lose billions of dollars and countless hours to translation friction. People spend years of their lives trying to master just one single language. But there are over 7,000 languages and dialects in the world. Learning them all is impossible. Experiencing this barrier is inevitable, you either already have, or you will soon.

At VertoX, we are building the world s first real-time, voice-to-voice translation infrastructure to solve this forever.

To turn this vision into a movement, we have just launched the official VertoX Reddit Community: https://www.reddit.com/r/Realtim...

I’m building BELLOCCO, a modern mafia browser game inspired by classic online games need feedback

Hey Product Hunt community

I m Robin, the solo developer behind BELLOCCO a free online mafia browser game where players build criminal empires, compete with rivals and create their own stories.

I started working on BELLOCCO because I loved the classic browser games where players formed alliances, competed for rankings and built something over time. Many of those games have disappeared or stopped evolving, so I wanted to create a modern version with a better experience.
