The 10 commandments of forex trading are ten habits that keep you in the game: learn before you risk money, trade only what you can afford to lose, plan each trade, control the size of every loss, and review your results honestly. They can't guarantee a profit, and following them doesn't make trading easy. What they do is protect you from the mistakes that end most beginners' accounts early.
Most of these rules are about you rather than the market, which is why they apply to any strategy. Below is each one with a practical step. Where we use numbers, we show where they come from. If you trade with an expert advisor (EA), there's a section on that at the end.
1. Learn Before You Risk Real Money
Know what a pip, a lot, a spread and leverage mean before your first live trade. These are the numbers that decide what a trade costs. A demo account costs nothing, so use it to learn the platform and make your first mistakes there. Keep in mind that demo trades don't feel the same as live ones, and they don't face the same execution.
Your step: work through our step-by-step guide to start trading, and keep the forex glossary open.
2. Be Realistic
Many traders lose money, and a small account won't replace a salary in a few months. There's no standard timetable for becoming good at this, and no guaranteed return at the end of it. Be careful with any monthly figure you see: it's the past, not a schedule. A good first goal has nothing to do with income. Keep to your rules for a few months and keep the losses small.
Your step: write down what you'd do with this money if you didn't trade. If the answer is something you need, read rule 4 before going further.
3. Know Your Strategy and Test It
A strategy is a set of rules for when you enter, where you exit and how much you trade. If you can't write yours down, you don't have one yet. Writing it down also lets you test it, because you can't test a feeling.
A test doesn't prove that a strategy will work. It shows how it might have behaved, including its losing runs. Many strategies have no real edge at all, and you can only start to find out with enough trades.
Your step: write your rules on one page, then test them on a demo account or on past data, as in How to Backtest an Expert Advisor.
4. Trade Only Money You Can Afford to Lose
If you need this money for rent, or you are paying off debts, stay on a demo account for now. That isn't a judgement: it's practical. When a loss would really hurt, you can't let a trade play out. You close too early, you move the stop, or you add to the position to get the money back.
Your step: choose an amount that you could lose completely without changing your life. That's your trading account.
5. Don't Let the Last Trade Decide the Next One
Results come in an uneven order. If a strategy wins 60% of the time, you'd expect about 20 losses in 50 trades on average, and you don't know which ones. It won't be exactly 20: in about 97% of such runs it's between 13 and 27 (our calculation, assuming independent trades).
Losing streaks are more common than they feel. Here is the chance of at least one streak of 5 or 8 losses in 100 trades:
| Win rate | 5+ losses in a row | 8+ losses in a row |
|---|---|---|
| 70% | 15.3% | 0.4% |
| 60% | 45.9% | 3.6% |
| 50% | 81.0% | 17.0% |
| 40% | 97.6% | 49.0% |
Our calculation, assuming independent trades. Real trades can cluster, so long streaks may be more common than this.
So five losses in a row isn't a signal that something broke, and it isn't proof that nothing did. It's a reason to follow the plan you made before the streak began, not to take revenge on the market. A win is the same: three good trades don't make the fourth one safer.
Your step: set a pause rule in advance, for example stop for the day after three losses or a 3% drop.
6. Accept Losses, but Control Their Size
You can't avoid losses, because they're a normal cost of trading. What you can decide is how big each one is. Many traders risk 1–2% of the account per trade. On a $2,000 account with a 1% risk, ten losses in a row cost about 9.6%. At 10% per trade, the same run costs about 65%.
The way back is also steeper than the way down: after −40%, you need about +67% to recover. A stop loss limits a loss, but it doesn't guarantee the exit price, because a fast market or a weekend gap can fill it further away.
Your step: work out your lot size from your risk and your stop, as Money Management in Forex shows, or use the lot size calculator.
7. Focus on the Process, Not the Money
You don't control the result of any single trade, but you do control whether you followed your rules. Watching the balance tick up and down pulls your attention to the one thing you can't influence, and it pushes you to close winners early and hold on to losers. A well-made trade can lose, and a careless one can win. So judge your trades by whether they followed the plan.
Your step: keep a simple journal. For each trade, note the reason, the risk and whether you followed the plan.
8. Plan Every Trade Before You Enter
When a trade is open, it's hard to think clearly. So make your decisions before you enter. Answer five questions first:
- Why am I entering, and does it meet my rules?
- Where is the idea proven wrong? That's the stop loss.
- Where will I take profit?
- What lot size makes the loss at the stop equal to my risk?
- What are the costs, and is any big news due?
Then leave the stop alone, unless your plan says how it moves. Our guide to forex risk management covers where the stop and target go, and how risk–reward fits with your win rate.
9. Skip Trades That Don't Meet Your Rules
You don't need to be in the market all the time. Every trade costs a spread, and every trade outside your rules is a trade you never tested. Waiting is a valid decision.
That doesn't mean that some setups are sure things. Trades look obvious afterwards, not before. So never raise your size because a trade “can't lose”. The setup that looks perfect takes the same risk as any other, and it can hit the stop just the same.
Your step: keep a short checklist from your strategy. If one item fails, you don't trade.
10. Review Your Rules, and Change Them Slowly
A plan isn't a promise to do the same thing forever. Don't give up on a strategy after a few losses, because that tells you almost nothing, and jumping from one system to another means you never collect enough results to judge any of them. But don't hold on for ever either: markets change, and strategies can stop working.
Review at fixed intervals, say every month or every 50 trades, not in the middle of a bad day. Decide in advance what would count as the strategy failing, such as a drawdown deeper than your limit. Change one thing at a time, and test it before you use it live.
Your step: put a monthly review in your calendar, and read your journal then.
Do These Rules Apply to Expert Advisors?
An EA removes some problems and leaves others. It follows its rules without fear or hope, but the decisions about risk are still yours, and so is the temptation to interfere.
| Rule | With an EA |
|---|---|
| Know your strategy | Learn how it trades, above all whether it adds to losing trades |
| Affordable money | Unchanged |
| Control losses | Set the size from your own drawdown limit |
| Ignore the last trade | Don't switch it off after a normal losing run |
| Review slowly | Write down the point at which you'd stop it |

FAQ
What are the most important rules of forex trading?
Trade only money you can afford to lose, decide your risk before you enter, size each trade from your stop loss, and follow a written plan. Together these keep single losses small enough for you to stay in the market.
How many losses in a row are normal?
More than most people expect. With a 60% win rate and independent trades, there's a 45.9% chance of at least one run of 5 losses in 100 trades. With a 40% win rate, the chance is 97.6%. Real trades can cluster, so treat these as a minimum.
Should I change my strategy after a losing streak?
Not straight away. A short streak says little about a strategy. Review it at a set time, with enough trades to judge, and against limits you chose in advance. If you pass the limit, pause it and find out why.
Do these rules guarantee a profit?
No. They reduce the avoidable damage, but they can't give a strategy an edge that it doesn't have, and you can follow all of them and still lose money.
The Bottom Line
- Learn first, and use a demo account while it's free to make mistakes.
- Trade only money you can afford to lose, with realistic expectations.
- Write down your strategy, and plan each trade before you enter.
- Control the size of each loss, because you can't avoid them.
- Expect losing streaks, and set your pause rule before they start.
- Review at fixed times, and change your rules slowly.
