Daily loss limit
A daily loss limit is the maximum amount or percentage of your account you are willing to lose in one day. Once you hit it, you stop trading for the day.
How it works
You set the limit in advance, for example 2–3% of the account or three losing trades in a row. When you reach it, you close the platform until tomorrow, even if you feel sure you can win it back right now. The point is that one bad day never turns into a disaster.
After a run of losses, decisions get worse: you want your money back, position sizes creep up and you take trades without a setup. A daily limit breaks that spiral before it eats a week or a month of work.
At prop firms the daily limit is a hard rule: break it and the account is closed. There it matters what it is measured from (balance or equity at the start of the day) and at what time of day it resets.
Account $5,000, daily limit 2%, which is $100. You risk $25 per trade. After four losers in a row the limit is used up and you stop. Your worst day costs 2% of the account, not the 10–20% that chasing losses can cost.
A common mistake is raising the limit during the day: just one more trade. A limit you keep moving does not work. Write it into your trading plan, set an alarm or use platform settings that cap losses if available, and log any breach as a separate mistake in your journal.
Questions and answers
What is a daily loss limit in simple terms?
It is an emergency brake for the whole day: once you lose a preset amount, you stop trading until tomorrow.
What daily loss limit should I use?
Many traders use 2–3 times their per-trade risk or 2–5% of the account. What matters is that your worst day cannot wreck your month and that you actually stick to it.
How is the daily loss limit calculated at a prop firm?
It depends on the firm: usually from balance or equity at the start of the trading day, resetting at a set server time. Check the specific firm's rules.
