The 5% rule is your real stop
Prop firm marketing talks about profit targets; survival is about daily loss limits. At Traders Club, funded and evaluation accounts typically use a 5% maximum daily loss from the day-start balance.
This guide is the companion to position sizing for prop firms — focused specifically on the 5% daily cap.
Session risk budget
Daily budget ($) = Account equity at 00:00 UTC × 5%
Examples:
| Account | 5% daily budget | |---------|-----------------| | $25,000 | $1,250 | | $50,000 | $2,500 | | $100,000 | $5,000 |
Never plan to use 100% of the budget on one trade.
Per-trade risk
A conservative split:
- 0.5% per trade → up to ~8–10 losses before daily breach (if you kept trading — you should stop earlier)
- 1% per trade → stop after 2–3 consecutive losses for the day
Rule of thumb: Stop trading for the session after −2R or −3% total, whichever comes first.
Worked example ($100K)
- Daily budget: $5,000
- Risk per trade: 0.5% = $500
- Stop on EUR/USD: 40 pips → size ≈ 1.0 lot (round down)
If trade 1 loses $500 and trade 2 loses $500, you are at −1% — consider ending the session. Revenge trade 3 at double size is how evaluations die.
Combine with max drawdown
Daily loss resets each UTC day; max drawdown does not. A string of −4% days still approaches the 10% static floor.
Read static vs trailing drawdown and handling losing streaks.

Frequently asked questions
- How much can I lose in one day on a prop firm account?
- At Traders Club, the daily loss limit is 5% of your balance at the start of the trading day (00:00 UTC). Open and closed losses count.
- What risk per trade fits a 5% daily limit?
- Many traders use 0.25%–1% of equity per trade, stopping after 2–3 full losses to stay inside the daily cap.
- Does one bad trade fail the challenge?
- A single trade can fail you if it exceeds the daily or max drawdown limit. Size so your largest plausible loss stays under your session budget.
