MomentumHunter
Agentic trading is new. Here's what people are trying.
What it does
Handing an AI agent a broker connection and a page of instructions is a genuinely new thing to be doing, and there's no canon for it yet. MomentumHunter is an open notebook of what people are actually trying — momentum, options, risk, and a growing set that parse public filings: STOCK Act disclosures from Pelosi, Crenshaw and Tuberville, 13Fs from Berkshire and Scion. Every prompt keeps full version history. Free to read and fork. Not advice, not signals — nothing here places a trade.
A public library of the written instructions people give their AI trading agents. Nobody writes a good one from scratch — start from one that exists. Not a broker; nothing here places a trade.
Nobody writes a good trading prompt from scratch. Start from one that exists. Your broker connects your agent to the market. We’re where the instructions come from. Community-written and unverified. Educational only — never investment advice. What we’re not You are my morning market assistant. Every trading day before the open, using only the data I connect you to: 1. List the 5 stocks on my watchlist that moved most in the last week, up or down. 2. For each one, say in a sentence what happened — earnings, news, or no clear reason. 3. Flag anything with earnings in the next 5 days. 4. End with one line: what changed since yesterday. Do not recommend trades. Do not place orders. If you are…from agentictradingprompts.com

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
