The Prop-Firm Risk Guardian

Fudoshin 不動心

Always-on discipline - %-of-drawdown daily stop, auto-flatten, tilt-proof lockout, and the signed Scrolls rules + news feed.

The risk rule you cannot switch off.

Fudoshin enforces your drawdown and daily-loss limits inside NinjaTrader, and once tilt-proof is armed, it takes four hours to turn off.


The 20 minutes that costs $50,000

Nobody blows an evaluation over a month. They blow it in one afternoon: down on the day, sizing up to get it back, and the risk tool that would have stopped them got switched off somewhere around the second revenge trade.

Every risk add-on on the market has the same flaw. It obeys you, including at the exact moment you should not be obeyed.

What Fudoshin does differently

Tilt-proof mode. Arm it and the lockout is not negotiable. It survives closing the window, closing NinjaTrader, and rebooting the machine. It clears at the next session, not before. Turning tilt-proof off starts a four-hour delayed disable that is written to disk, so a restart cannot dodge it. You cannot loosen your risk type, un-manage an account, or edit enforcement settings while it is armed.

That is the product. Everything else is support.

The rest of it

  • Loss limits as a percentage of drawdown. Not a fixed dollar figure, set separately for evaluation, funded, and cash accounts. On a $2,000 drawdown, 10% flattens you at -$200. Change account size and the limit scales with you.
  • Profit lock. Locks the account when you reach an R-multiple of your loss limit. Giving back a good day kills more funded accounts than any single loss.
  • Consistency lock. Computes the maximum today’s profit can reach and keep you payout eligible, then enforces the tighter of that and your profit target.
  • Order intercept. Cancels entries that breach your contract cap, or any entry placed while you are locked out. Never blocks an exit, a reducing order, or a protective bracket.
  • News auto-flatten. Flat before high-impact releases, flat through the window, trading again after.
  • Session-aware resets. Eastern time, DST-aware, per calendar day or per trading session (Asia, London, New York).

The Scrolls

120+ prop-firm rulesets ship in a signed feed: Apex, Topstep, FundedNext, TopOne, BluSky and more, each with its drawdown type and amount, daily loss, consistency share, contract limits, and the date the numbers were last verified.

The feed is Ed25519-signed. Fudoshin verifies the signature, then verifies every firm file’s hash, before anything loads. Rules that do not verify never reach the engine. Anything you edit yourself is protected from feed updates, and if your plan is not in the feed, the Ruleset Builder lets you add it.

It works offline

Enforcement is local. It runs inside NinjaTrader on your machine and needs no server, no network, and no login. The cloud only ships the rules and the news calendar.

Proof it is working

Every warn, flatten, lock, and unlock goes to an append-only activity log with the reason and the numbers at the moment it fired: “DailyStop: Day P&L -315; -115 loss room left”.

Who it is for

Prop traders on NinjaTrader 8, in evaluation or funded, who have blown an account and know exactly how. Multi-account traders who need the same rules applied consistently everywhere.
