LAYER 0 — Trading Decision Firewall

The firewall that stops a bad trade before it happens

What it does

Trading journals (TradeZella, Edgewonk, Fillbook) record what already happened — none stop the trade before it starts. LAYER 0 is a mandatory pre-trade gate (7 questions, one verdict) plus a real 20-minute lockout after a loss. Optional Commitment Contract stakes real money on your own discipline. Built by a funded prop trader who lost six figures to undisciplined trading. Goal: daily, honest use moves a trader from reactive gambler to calm and consistent — tracked by process, never P&L.

The app to stop revenge trading, overtrading, and breaking your daily loss limit. LAYER 0 is a pre-trade firewall, journal, and tracker for prop firm, funded, and independent traders.

Free for 7 days, no card required. Then $14.99/mo — locked in for life, guaranteed Most trading damage doesn't start with a bad setup — it starts with a bad state, one that's already active long before it shows up on the account. “Stop being the gambler in the casino. Become the owner of the casino.” Five stages, gated on process — never P&L. A real progress path, not another P&L number, with a shareable stage card at every step. Illustrative sample — the real card generates from your own stage and streak. Answer 7 questions before you open a chart. Mood, sleep, recent losses, revenge impulse, overconfidence after a win — the real variables. The app returns one of three verdicts: Proceed,…from layer0firewall.com

    Post-Opus 4.6, LLMs feel much better at using bash, code, local files, and tools. So I kept coming back to a simple question: if a model can use a computer reasonably well, why can’t I just give it my broker account, a strategy, and let it trade? My conclusion is that the blocker is not model capability in the abstract. It is the system around the model. A raw LLM breaks on a few practical things almost immediately: • no persistent operating memory across sessions • no trustworthy record of what it did and why • no hard approval boundary before money moves • no cheap always-on monitoring if…

    Built a 200k-edge market knowledge graph to filter false dip-buy signalsDec 2025 · ▲5

    I’ve been experimenting with a graph-based approach to a classic trading problem: why most dip-buying strategies can’t tell the difference between a temporary overreaction and a genuine structural collapse. Most systems treat a −5% move the same regardless of context. My hypothesis was that where a company sits in the market’s structure matters more than the price move itself. The engineering idea I built a knowledge graph of the U.S. public markets with ~207k edges across ~21 relationship types, organized into four layers: Operational: supply-chain relationships (SUPPLIES_TO, PRODUCES)…

    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…

  • 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.
