Stop-loss and max-risk-per-trade rules at prop firms, explained
Some firms make you attach a stop-loss to every trade, some cap how much one trade can risk, and some leave it entirely to you. Here is how per-trade risk rules differ across the firms we track.
Daily loss limits and overall drawdown get most of the attention. But a growing number of firms also police individual trades — either by requiring a stop-loss, or by capping how much a single position may put at risk.
These rules are easy to miss because they often sit in a help-centre article rather than on the pricing page. This neutral explainer walks through the main approaches using firms in our dataset. Always confirm the current rule for your exact product on the firm's own pages.
1. Mandatory stop-loss on every trade
The simplest version: every position must carry a stop-loss.
- Top One Trader lists "stop-loss required per trade" across several of its plans, including 1 Step FLASH and its Instant Funding products. On some plans it is a soft breach (a warning rather than instant failure), and an add-on is offered to remove the requirement.
- Fintokei describes a stop-loss requirement as one of several measures that can be applied if its gambling-detection system flags an account — so it is conditional rather than universal.
What to check: whether the stop must be set on entry or merely before some time limit, and whether a missing stop is a soft or hard breach.
2. A cap on risk per trade
Instead of requiring a stop, some firms cap the potential loss on any one position — usually as a percentage of the account:
- Upcomers: funded accounts carry a max risk per trade of 3% of initial balance, listed as a hard breach.
- Fintokei: a maximum risk on open trades of -3% is cited across its programs (we flag parts of this as unverified).
- Blueberry Funded: funded accounts on several plans carry a per-trade risk rule of around 1.5%.
A per-trade cap effectively forces stop-loss discipline: without a defined stop, there is no clear way to show your risk stayed under the limit.
3. No per-trade rule at all
Many firms rely only on the daily and overall drawdown limits. Funded Trading Plus, for example, states "no stop-loss requirement" on its Instant Funding (Master Trader Program) plan — while still requiring all positions to be closed before the weekend.
No rule doesn't mean no risk. A single unprotected trade can still hit the daily loss limit in one move.
Why the evaluation-vs-funded split matters
Notice a pattern: several of these rules apply only once you're funded. A trader who passed the evaluation using wide or no stops can find their style suddenly non-compliant after funding. Our guide to what changes after you pass covers this in more depth.
How these rules interact with other limits
- Lot caps vs risk caps: a lot or contract limit restricts size; a risk cap restricts size × stop distance. You may need to satisfy both.
- Martingale and averaging down: Blueberry Funded explicitly prohibits martingale — even a small lot increase after a loss. Per-trade caps often travel with banned-strategy lists.
- Automation: if you run an EA, make sure it attaches stops and sizes positions within the cap. See our AI & automation hub.
Key takeaways
- Per-trade rules come in two forms: a mandatory stop-loss, or a cap on risk per position (often around 1.5%–3%).
- Many of these rules apply only on the funded account — not during the evaluation.
- Check whether a breach is soft (warning) or hard (account ends).
- Firms with no per-trade rule still enforce daily and overall drawdown.
