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.

I built LAYER 0 after nearly losing six figures — and my family — to undisciplined trading. It wasn't a bad strategy. It was no risk management, ever, and no friction between impulse and action. Every trading journal I tried just recorded what already happened. None of them stood between me and the market on the days I was the biggest risk in the room. So I built the gate I wished had existed: 7 questions before every session, a verdict before you open a chart, and a real 20-minute lockout after a loss — not an alert you can dismiss, an actual pause. Free to start, 7-day trial, no card required. Happy to answer anything — pricing, how the verdict logic works, what counts as a breach on the optional Commitment Contract, whatever.
