Prop-Challenge Risk & Survival Suite

Stop Donating Reset Fees to Prop Firms. Stress-Test Your Strategy Against Drawdown & Consistency Rules in Claude or Cursor Before You Buy a Challenge.

Why 90%+ of Prop Evaluations Fail

Most retail traders fail prop evaluations not because their entry signal has negative expectancy, but because they size for raw return instead of path-dependent survival: hitting the 5% daily loss floor during a 2-sigma losing streak, violating the 30%–40% single-day consistency rule on a windfall session, or giving back gains at 75% of the profit target instead of engaging a 0.55x Target-Lock Taper.

Tool Plan & Cost What It Enforces & Computes
warden.prop_challenge_check Free (0 credits, runs locally) Evaluates TwoStep (5% daily / 10% max loss / 8% target) and OneStep (4% daily / 6% trailing loss / 10% target) rules, 30%–40% consistency caps, spread + overnight swap friction, and the 0.55x Target-Lock Taper at ≥70% of profit target.
warden.defensive_posture Free (0 credits, runs locally) Classifies market & portfolio telemetry into Normal (1.0x), Cautious (0.68x), Defensive (0.42x), or CrisisShield (0.20x) with stop-tightening and aggregate stop-heat caps.
gym.prop_challenge_sim Pro (1 credit on hosted, 0 locally; covered by 100 free signup trial credits or £19 / ~$24 / €22 Starter pack) Simulates up to 500 multi-day evaluation paths on your trade R-multiples to output exact Pass Probability (%), Daily Breach Probability (%), Consistency-Lock Frequency (%), and the Optimal Risk-Per-Trade (%) that maximizes expected net payout minus challenge fees.

60-Second Copy-Paste Prompt for Claude Desktop / Cursor

Install quant-swarm (uvx --from quant-swarm swarm-warden-mcp and swarm-gym-mcp) and paste this prompt into Claude or Cursor:

Audit my last 50 trades for a $100,000 TwoStep prop-firm challenge (5% daily loss limit, 10% max loss limit, 8% profit target, 40% consistency rule):
1. Call warden.prop_challenge_check on my current account state and next proposed trade to verify safe daily drawdown buffer, consistency cap headroom, and whether 0.55x Target-Lock Taper is active.
2. Call warden.defensive_posture to check whether current volatility and drawdown require tightening stops or scaling down risk.
3. Call gym.prop_challenge_sim with my trade R-multiples across 500 paths to find the exact risk_pct_per_trade that maximizes my pass probability and expected net payout after a $500 challenge fee.
