LAYER 0 — Trading Decision Firewall

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 (Proceed/Caution/Stop), plus a real 20-minute lockout after a loss, not a dismissible alert. Optional Commitment Contract: stake real money on your own discipline, forfeited to a charity you pick if you break your rules. Built by a funded prop trader who nearly lost six figures to undisciplined trading.
