Forex Risk Management: The Rules That Keep You in the Game
Every strategy has losing streaks. Risk management decides whether a losing streak is an annoyance or the end of your account. These are the core rules, and the maths behind them.
Risk management means deciding what you can lose before the trade. Fix a risk per trade, commonly between 0.25% and 1%, size the position from the stop distance, cap the day with a loss limit, and never widen a stop. It decides survival far more than entries do.
Rule 1: Risk a small, fixed percentage per trade
Decide the most you'll lose on any single trade as a percentage of your account, and keep it the same every time. Many traders use 0.25% to 1%. Small, fixed risk keeps losing streaks survivable and makes results comparable.
Rule 2: Always know your stop before you enter
The stop loss is where your trade idea is proven wrong, not a random number of pips. Place it at the structural invalidation, then size the position so that hitting it costs exactly your fixed risk. Our lot size calculator does the maths.
Rule 3: Think in R
"R" is the amount you risk. A trade that makes twice the risk is +2R; a full stop-out is -1R. Thinking in R lets you judge a method independently of account size. It also shows why reward-to-risk and win rate are linked: at 1:2 reward-to-risk you can be wrong more often than right and still come out ahead, before costs.
| Reward:risk | Break-even win rate (before costs) |
|---|---|
| 1:1 | 50% |
| 1:1.5 | 40% |
| 1:2 | 33% |
| 1:3 | 25% |

Set a point at which you stop trading for the day, for example 2% or three losing trades. Most blow-ups aren't one bad trade; they're a bad day followed by revenge trades. Prop firms enforce daily limits for exactly this reason.
Rule 5: Respect the drawdown maths
| Loss | Gain needed to recover |
|---|---|
| 10% | 11% |
| 20% | 25% |
| 30% | 43% |
| 50% | 100% |
Losses compound against you. Small risk per trade keeps you in the shallow part of this table.
Rule 6: Watch correlation and news
Three trades on EUR/USD, GBP/USD and AUD/USD are often one bet against the US dollar. Count correlated positions as one when you add up your risk. Spreads can widen sharply around major news, so a stop may fill worse than planned.
Frequently asked questions
What is the 1% rule in forex?
Risking no more than 1% of your account on any single trade. It keeps a normal losing streak from doing serious damage.
What is a good risk-to-reward ratio?
There's no single best ratio. Higher reward-to-risk lowers the win rate you need to break even, but targets must still be realistic for the setup.
Should I always use a stop loss?
A predefined exit is essential for controlling risk. Without one, a single adverse move can do disproportionate damage.
How do I stop revenge trading?
Set a daily loss limit and stop when it's hit, reduce size after losses, and review trades away from the screen.
