Daily Loss Limit Calculator — Frequently Asked Questions

Q.What is the FTMO daily loss limit?

FTMO daily loss limit is 5% of the initial account balance. For a $100K account = $5,000 per day. For a $50K account = $2,500. The daily loss is calculated on the balance at the start of each trading day, not on open positions — so unrealized losses count.

Q.Does the daily loss limit reset every day?

Yes — the daily loss limit resets at the start of each new trading day. For FTMO, the reset is at midnight CET. For TopStep, it resets at 5:00 PM CT. Always check your firm's specific reset time. Positions held overnight may have their floating losses count against the next day's limit.

Q.What happens if I breach the daily loss limit?

Breaching the daily loss limit immediately fails the challenge or funded account — there is no grace period or warning in most firms. Some brokers auto-close all positions at the moment the limit is hit. Prevention: set a hard stop in your trading platform at 80% of the daily limit and refuse to trade past it.

Q.Should I risk the full daily loss limit each day?

Never. Professional prop traders treat the daily loss limit as a hard ceiling, not a target. Most experienced funded traders stop trading after losing 40–60% of their daily limit. If you lose $2,000 on a $5,000 daily limit day, stop. Come back tomorrow fresh — protecting the account is more important than revenge trading.

Q.How do I avoid hitting the daily loss limit?

Set a personal daily loss limit at 50% of the firm rule. If FTMO allows $5,000 daily loss on $100K, stop trading at $2,500 loss. Use a position size calculator so no single trade can lose more than 25% of your daily limit. Take a mandatory break after 2 consecutive losses.
