Why do traders fail from trailing drawdown?
They often keep trading after the drawdown floor has moved up. A normal pullback can become a rule violation if the trader does not know the current floor.

Estimate the account floor that can end an evaluation, even when you are profitable overall.
Trailing drawdown is a moving loss limit. As your account reaches new highs, the danger line can move up too. This calculator helps you see the estimated floor, remaining cushion, and a cautious risk amount before you trade.

Example Walkthrough
$100,000 account starts with a $3,000 maximum drawdown.
The account reaches $103,000, so the trailing floor may rise to $100,000.
If equity drops to or below that floor, the trader may fail the account.
Common Mistakes
- Risking more after a winning streak.
- Confusing trailing drawdown with static drawdown.
- Ignoring open trade losses during the day.
- Trading larger because the profit target feels close.
Checklist Before Trading
- I know where the current drawdown floor is.
- I know today's daily loss room.
- My stop loss is planned before entry.
- My risk is small enough to survive a losing trade.
FAQ
Is trailing drawdown the same at every prop firm?
No. Some firms trail from balance, some from equity, and some stop trailing after a certain point. Always check the official rule page.
Should beginners avoid trailing drawdown accounts?
Not always, but beginners should use smaller risk and track the floor carefully. Static drawdown rules are often easier to understand.
What should I calculate before a trade?
Know the drawdown floor, account cushion, daily loss room, and planned dollar risk before entering.
