NinjaTrader® Account-Guard Add-On
Your limit only works – until you decide to break it.
After three losing trades, you're no longer thinking as clearly as you were before them. The next setup suddenly looks like a chance to make it all back, the position gets bigger, and the stop moves further away. Not because you lack discipline – decisions made under pressure are systematically worse. That's how a single day can erase what took weeks or even months to build.
Willpower is weakest on exactly the day you need it most.
I needed this myself – so I built it.
I didn't build this as a product. Every tool on this site started by solving a problem in my own trading. Account Guard runs on my accounts every trading day, and it's the reason a bad session stays a bad session instead of turning into a bad week.
If it works for my trading, it can work for yours.
How Account Guard works
Set your limit once – per account, as a fixed dollar amount or a percentage of your trailing maximum drawdown.
It activates the next trading day. Change it anytime on ArtyTrades.com, and the new limit takes effect the following trading day.
Limit hit → instant lock. Open positions are closed immediately, and the account is locked until the next trading day. No confirmation dialog. No "just one more trade."
The NinjaTrader® add-on installs in seconds and runs quietly in the background from then on. That's what automated risk management inside NinjaTrader 8 looks like in practice: one decision, made once, enforced every trading day.
Your risk management runs even when you don't want it to
Automated daily loss and trade limitFixed dollar amount or percentage of your trailing max drawdown. Once it's hit, Account Guard locks your NinjaTrader account instantly – without your input.
Per-account configurationOwn capital, broker account, or evaluation – define separate limits for each. Optimized for the rules of Apex, Topstep, MyFundedFutures, and other leading providers.
Discipline without willpowerThe automated or manual account lock ends revenge trading and the urge to "make back" losses before it starts.
