You didn’t fail your last challenge because of your strategy. You failed it on the one day you broke your own rules: the revenge trade, the extra position, the “just one more”.

Trader OS is a journal built for that day. You set your rules when you’re calm. It enforces them when you’re not.

What it does

• Prop firm mode: daily loss limit, max drawdown (static or trailing) and profit target, tracked live. You always know how much room you have left.
• Tilt lock: after X losses in a row or your max trades for the day, the app locks until midnight.
• Pre-trade checklist: every rule you skip is saved with the trade.
• The number that hurts: Stats show exactly how much money breaking your rules has cost you.
• Live TradingView chart, equity curve, P&L calendar and breakdowns by setup and emotion.

Costs less than one failed challenge.

One failed evaluation can cost you $100 or more. Trader OS is €24.99, once. No subscription, no Notion, no spreadsheets.
