Risk management in trading
If you've ever lost half your capital in two trades, you don't have good risk management.
I'd go further: you don't have any...
Contrary to what beginners might think, a trader's goal isn't to make as much money as possible on every trade.
A trader's goal is to make more in profits than they lose over the long term.
That's why good risk management matters.
Let me be clear: good risk management doesn't prevent losses. It only limits them.
The 2% rule in trading
The 2% rule says you should never risk more than 2% of your capital on a single trade.
It's a very well-known, ready-made rule you'll find all over the internet.
It's recommended to beginners, although I have doubts about using it in practice.
Why?
In theory, it looks like a very cautious approach when you're starting out.
Take a concrete example. You have €5,000 in your trading account:
2% of €5,000 = €100
Under the 2% rule, you shouldn't risk more than €100 per trade.
It would take more than 35 consecutive losing trades to lose 50% of your capital.
The 2% rule helps you stay in trading over the long term and stops a series of bad trades from taking you out of the game.
For a beginner, it provides a money-management framework.
You won't take reckless risks by putting your entire account on one trade.
It's theoretical protection against large losses while you're learning.

How to apply the 2% rule
- Calculate 2% of your total capital
- Determine your stop loss before entering a trade
- Calculate how many coins or shares you can buy
For example:
You have €10,000 and follow the 2% rule, so you're willing to risk €200 per trade.
Suppose you're trading a cryptocurrency priced at €50.
You've identified support at €48, where you'd place your stop loss if the trade moves against you.
To calculate how many coins you can buy, divide your risk amount by the difference between your entry price and stop loss.
In this case:
€200 / (€50 - €48) = 100 coins
You can buy 100 coins.
If price falls to your €48 stop, you lose €2 per coin, or €200 in total: 2% of your account.
Losing scenarios: with and without the 2% rule
Imagine starting with €10,000 in your account. You're incredibly motivated and think you'll be buying a Lamborghini within 3 months.
Scenario 1: Without the 2% rule
You decide to risk 20% of your account on every trade.
I don't need to tell you that's a huge mistake.
Here's what could happen:
- Trade 1: -20%, a €2,000 loss, leaving €8,000
- Trade 2: -20%, a €1,600 loss, leaving €6,400
- Trade 3: +15%, a €960 gain, bringing you back to €7,360
- Trade 4: -20%, a €1,472 loss, leaving €5,888
In just 4 trades, you've lost more than 40% of your starting capital.
You now need a 70% gain to return to €10,000...
Can you see why the average beginner trader loses €10,000?
Scenario 2: With the 2% rule
Now let's apply the 2% rule:
- Trade 1: -2%, a €200 loss, leaving €9,800
- Trade 2: -2%, a €196 loss, leaving €9,604
- Trade 3: +1.5%, a €144 gain, bringing you back to €9,748
- Trade 4: -2%, a €195 loss, leaving €9,553
After the same sequence, you've lost only 4.5% of your starting capital. You need just a 4.7% gain to return to €10,000.
See the difference?
With the 2% rule, you're still in the game even after a losing streak.
Remember: your priority in trading should be surviving long enough to become profitable.
Why set your stop loss before entering a trade?
A stop loss is a predefined order that automatically closes your position if price reaches a certain level.
- It protects you against excessive losses if the market turns against you
- It stops you staying in a losing trade out of hope or fear
- Setting it beforehand helps you follow your trading plan instead of your emotions
But be careful. Placing a stop loss isn't about choosing a random percentage. It needs to be positioned strategically based on your market analysis.
How do you place it properly?
- Analyse the chart to identify levels that would invalidate your plan, such as support and resistance if you use chart analysis
- Place your stop at the identified level
- Calculate your position size and enter the trade
This makes your stop meaningful in relation to the market while respecting your risk management.
The limits of the 2% rule
Here's my view, though:
Giving one fixed rule to traders who trade differently isn't ideal.
It's easy to see why.
Telling someone who trades 8 times a day and someone who takes 1 trade a week to both follow the 2% rule makes no sense...
The first could risk more than 50% of their capital across 40 trades in the week, while the second risks 2%.
You need to adapt the rule to your trading.
Another thing that bothers me is that a professional trader's average monthly return target is 3% to 6%.
Under the 2% rule, they risk their entire target in just a few trades.
And that's not all. An experienced trader knows how to recognise opportunities and doesn't need arbitrary risk rules.
- Limited potential gains: they may identify exceptional opportunities where risking more would be worthwhile
- Less flexibility: professionals often adjust risk to the quality of an opportunity, not just a fixed percentage
- Experience left unused: over time, a trader develops a feel for the market that can justify departing from the rule
If they judge the probability of success to be low, for example, they might risk 0.5% instead of 2% to limit the loss.
This flexibility isn't for beginners. It takes years of experience and a deep understanding of the market.
