Risk management in trading
How to decide how much you can lose on a position and how much to allocate, before you open the trade. The rules that keep an account alive long enough for your edge to matter.
What risk management is
Risk management is the set of rules by which you decide how much you can lose on a position and where you exit, before you open the trade. It doesn't tell you what to buy — it tells you how much and how far. Strategy answers "what and when"; risk management answers "how much and what if I'm wrong".
It has two sides that work together. Risk management answers "how much do I lose if the market goes against me" — through the stop-loss and the percentage risked. Money management, or position sizing, answers "how much do I allocate" — how many units you buy so the loss stays within the limit you set. The reference sources (Van Tharp, the CMT curriculum) treat them as a single discipline with two components. We keep them together on this page.
In trading (short positions, often with leverage) risk is controlled through the stop-loss and the sizing of each position. In long-term investing the logic differs: risk is managed through diversification, time horizon and allocation, not through a strict percentage stop. This page covers the trading side. For the other one, see Investing.
Did you know
A loss of 50% of your account requires a 100% gain just to get back to where you started. That's not an opinion — it's arithmetic. That's why protecting your capital matters before profit.
Why most people lose
Between 74% and 89% of retail (non-professional) investor accounts lose money trading CFDs. The figure comes from the analyses of national authorities across the EU, synthesized by ESMA.
Source: ESMA — product intervention measures, 2018, still in force today (esma.europa.eu).
The 74–89% figure refers to CFD accounts, leveraged instruments. It does not describe classic investing in directly held shares, where the risk profile is different.
"Non-professional" means, in plain terms, an amateur: someone who doesn't trade as a regulated profession. And many amateurs study a little, study the wrong things, or don't study at all. Where, then, would good results come from? Without a strategy with clearly understood rules, without risk management and without an account suited to the goal, not even the best self-control saves the account. The components work together — none of them covers the absence of the others.
The reason isn't only a lack of good ideas. A trader can be right many times and still end up in the red, if management mistakes wipe out the profit. Since this page is about management, here we look at the causes that have to do with money and percentages:
- No stop-loss. The first and most costly one. Without an exit point set in advance, a single position can swallow the profit of dozens of successful trades. (Detailed in chapter 4.)
- Too much risk per trade. How much of the account you put at stake on a single position. The most common sizing mistake. (Chapter 3.)
- Too much risk per account. How many positions you keep open at the same time and how correlated they are — total exposure, not just the individual one. Ten "small" positions in the same direction add up to a big risk. (Chapter 10.)
- Adding to losing positions. Buying more of a position that is already losing. It's a tactic used deliberately in some approaches, but it works only if it's calculated in advance and framed within a fixed risk budget. Done emotionally, to "recover quickly", it's among the fastest ways to empty an account.
Locking means opening an opposite-direction position, of the same size, on the same instrument, without closing the losing position. The loss appears "frozen", but it doesn't disappear. In reality it's a deferred stop-loss: you're left with the same loss, plus double the spread and swap, plus two positions to manage instead of one. The moment you freeze decides nothing — it merely puts the unpleasant situation on pause, and one day it still has to be resolved. If you see a good opposite-direction idea on the same asset, that is a new trade, judged on its own merit — not a lifeline for the first one, because it doesn't work that way. Specialist sources are almost unanimous: a tactic for experienced traders with steady nerves, unsuitable for beginners.
Retail (non-professional) investors benefit from negative balance protection — you can't lose more than you deposited. Plus an automatic close-out rule (margin close-out) when margin falls below a threshold. It protects you from uncontrolled loss, but it does not protect your deposit itself.
Risk on a single position
The most cited rule in trading education: don't risk more than 1–2% of your capital on a single position. Important: 1–2% is the ceiling, not the target. It's fine to risk even a few tenths of a percent per trade — the less you risk, the longer the account survives a string of losses. If you have 10,000 USD and you risk 1%, the maximum accepted loss on that trade is 100 USD; at 0.5%, it's 50 USD — no matter how sure you feel about the idea.
Why a fixed percentage and not a fixed amount: the percentage adjusts itself as the account grows or shrinks. You risk less in absolute value after a string of losses and more after a string of wins. That way you avoid emptying your account exactly when things go badly.
Ideally, you trade without effectively using leverage — that is, the position value should not exceed the account's capital, or at least not on the individual trade. Leverage doesn't increase your edge; it only amplifies the result, in both directions. Details in chapter 8.
1–2% is a widely used convention, not a guarantee. The right percentage depends on your risk tolerance; what matters is that it stays the same on every position, regardless of style or frequency.
Professional traders and institutions usually risk a small fraction of capital per position and put capital preservation ahead of a quick gain. But they operate with large accounts, under strict mandates and risk limits, often with other people's money and with different goals — hedging, liquidity, obligations to clients. That's why you shouldn't copy their numbers; copy the discipline. For a small account, small percentages matter all the more.
Did you know
With a risk of 1% per position, you'd need almost 70 consecutive losses to lose half your account. At 10% per position, you get there in just 7. That's the difference between staying in the game and being knocked out of it.
Stop-loss: where to place it
A stop-loss is the order that automatically closes the position at a preset price, to limit the loss. Its location is decided by the market, not by the account: the stop sits where your trade idea becomes invalid, not where "you feel comfortable". Then you adjust the size of the position to the stop, not the other way around.
Three ways to place the stop, from best to weakest
- Structural — below a support or above a resistance, where the chart tells you the idea was wrong. The best one, because it's tied to the market. See Technical analysis.
- Volatility-based — at a distance of a few ATR (the average range of the move). It adapts to how agitated the instrument is.
- Fixed — an amount or a percentage set in advance. Common, but usually wrong: it ignores market structure and places the stop where it suits you, not where it matters. Exception — algorithmic strategies (for example martingale-type ones), where everything is systematized and fixed by rule.
Position sizing
This is where everything connects. Position size doesn't start from "how much do I want to buy", but from two figures already established: the amount you accept losing (chapter 3) and the distance to the stop (chapter 4).
Example: a 10,000 USD account, 1% risk = 100 USD. You enter at 50 USD, you place the stop at 48 USD → the distance is 2 USD. Size = 100 ÷ 2 = 50 units. If you move the stop closer (49 USD, a 1 USD distance), you can buy 100 units at exactly the same 100 USD risk.
The counterintuitive idea: risk and the stop determine how much you buy, not the other way around. Van Tharp shows that position sizing matters more for the long-term result than the entry signal — exactly the part most people ignore.
This also explains the difference between styles: a scalper, with a tight stop, uses a larger volume; a swing trader, with a wide stop, a smaller volume — at the same percentage risked. Style changes the volume, not the percentage risk.
Position-sizing calculator
The example below is on a currency pair. Change the values and see how the stop and the percentage risked decide your position size. Try a closer stop or a smaller percentage and watch how much the result changes.
Important: 1 lot on a forex CFD is usually 100,000 units. On CFDs for gold, oil, indices, crypto and other assets, the size of a lot (contract size) differs — check it in your broker's platform.
The distance to the stop is the price difference between entry and stop. Volume = amount risked ÷ distance ÷ lot size, rounded down to 0.01 lot (the minimum tradable). The size of a lot differs by instrument — check with your broker.
The risk/reward ratio
The risk/reward ratio (R:R) compares how much you risk with how much you target. You risk 100 to win 200 → an R:R of 1:2. It's the second number in the equation, after the percentage risked.
R:R and the win rate work together — neither one alone tells you whether you're in profit. With a good R:R you can be right rarely and still win. With a bad R:R, you need a very high win rate just to stay flat:
| Risk/reward ratio | Minimum win rate to break even |
|---|---|
| 1:1 | over 50% |
| 1:2 | over 33% |
| 1:3 | over 25% |
Hence the classic mistake: traders who "are right often" but lose, because they close their wins quickly and let their losses grow — an inverted R:R.
R-multiple and mathematical expectancy
R is your risk unit: 1R = the amount risked on a position. If you risk 100 USD and win 250, you have a result of +2.5R. If you hit the stop, you have −1R. By expressing everything in R, you compare trades of different sizes on the same scale.
Mathematical expectancy tells you how much you win on average per position, over the long run:
If the result is positive, the system has an edge. If it's negative, you lose over time even if you have good days. That's the difference between a real edge and an impression.
Did you know
A system with a win rate of just 35% can be profitable over the long run, if each win is 3 times larger than each loss (+0.40R per position on average). The win rate alone doesn't tell you whether you're in profit.
Expectancy and the win rate are calculated on your real trades, not from theory. You need a sample of ~30–50 trades for the numbers to mean something. That's where The trader's journal comes in.
Leverage and margin
Leverage lets you control a position larger than the amount you deposited. With 1:30 leverage, 1,000 USD controls a 30,000 USD position. It amplifies in both directions — both the gain and the loss. It's not a source of profit; it's a multiplier of the result, whatever it may be.
Margin is the amount locked as collateral for the position. When losses erode it below a threshold (50% of the minimum margin, at regulated brokers), the position closes automatically — so you don't fall into an uncontrolled loss.
Common myth
Many believe that a high-leverage account is automatically a risky account. It isn't. Leverage only states how much you can use on top of your real money; the real risk comes from the volume you actually put into the trade. A car that can do 220 km/h on the dial isn't automatically dangerous — the risk depends on how hard you press the accelerator. The risky one may be the driver, not the car; the trader, not the account. Many experienced traders use effective leverage below 1:10, regardless of how much the broker offers.
ESMA leverage caps for retail (non-professional) investors
In force since 2018, still active. The more volatile the asset, the lower the allowed leverage — so that the risk is comparable across instruments:
| Instrument | Maximum leverage |
|---|---|
| Major currency pairs | 30:1 |
| Non-major pairs, gold, major indices | 20:1 |
| Commodities (excluding gold), non-major indices | 10:1 |
| Individual shares | 5:1 |
| Cryptocurrencies | 2:1 |
Source: ESMA (esma.europa.eu). The caps apply at EU-regulated brokers, for retail (non-professional) clients.

Drawdown and the risk of ruin
Drawdown is the drop in the account from a peak to a trough, expressed as a percentage. A 20% drawdown means you've lost a fifth of the maximum capital you reached.
Recovery isn't symmetric. The deeper the hole, the more disproportionately the gain needed to get back to zero grows:
| Drawdown | Gain needed to recover | How often it's salvageable |
|---|---|---|
| −10% | +11% | common, manageable |
| −20% | +25% | it happens, still salvageable |
| −30% | +43% | hard, but possible |
| −50% | +100% | rare |
| −60% | +150% | very rare |
A drawdown of 20–30% isn't "normal", but it does happen sometimes and can be recovered. Beyond 60%, however, accounts are very rarely saved — the math of recovery becomes prohibitive.
Drawdown codes
That's why a good trading and risk management system doesn't keep the same rules forever — it changes them as the drawdown deepens. You can think of them like weather codes:
- Yellow code — 10%. You already behave differently: you reduce position size, you look at what's not working, you slow down.
- Orange code — 20%. You seriously cut back risk, maybe stop for a few days and reassess the system.
- Red code — 30%. A critical threshold. You stop, analyze in detail, and don't resume until you understand the cause.
The 10/20/30% figures aren't a global standard — they're just an example by way of comparison. You can set your own thresholds, often smaller, according to your tolerance and your system. The idea that matters stays the same: the deeper you go into drawdown, the harder the recovery, and from a certain point it becomes practically impossible. That's why a careful study of drawdown thresholds helps you build a better and safer trading system.
The basic rule goes against instinct: you reduce position size after a string of losses, you don't increase it to "recover quickly". Increasing it after losses is the shortest road to an empty account.
Many prop accounts (with capital provided by a firm) close access at a total drawdown of around 10% — a yellow code for you, but a red line for them. The industry standard is around 5% daily loss and 10% total drawdown, beyond which the account is finished. Hence some people's reservations about them: a bad run of a few days can close the account with no right to return.
The risk of ruin is the probability that a string of losses closes your account before you get a chance to recover. It rises rapidly the more you risk per position — exactly what the "Did you know" in chapter 3 shows.
Correlation and total exposure
Risk isn't measured only per position, but across the entire open portfolio. Three long positions on instruments that move together (for example three pairs with USD) aren't three separate risks — they are in reality a single risk, three times as large.
Correlation measures how much two assets move together. Positively correlated positions add up the risk; negatively correlated positions partially offset it. You can check it quickly with the correlation matrix before opening several positions on related instruments.
Total exposure: even if each position respects the 1% rule, ten correlated positions opened simultaneously can mean 10% of real risk in a single direction. That's why you limit not just the risk per position, but also the combined exposure.
Your risk management plan
All the rules above matter only if you apply them consistently. That's why they're written down — before the market opens, when your mind is clear, not in the middle of a losing position.
A risk management plan contains at least:
- The maximum percentage risked per position
- The maximum total exposure open at the same time
- The stop-placement rule
- The minimum accepted risk/reward ratio
- The drawdown limit at which you stop and reassess
The discipline of risk rests on two others: recording — so you can see whether you really follow the rules — and psychology — so you follow them even when it hurts.
Risk toolkit (Excel)
Two tools that do what a page can't: a position calculator (size any trade from risk, stop and lot size) and a strategy simulator. You enter your win rate and your R:R, and the simulator shows you how the account would evolve, with real drawdowns and losing streaks. You press a key and see another scenario: the same parameters, but a different order of wins and losses — because order matters just as much as the win rate. It works in Excel and Google Sheets. We send the toolkit to your chosen channel, and in your Personal Cabinet you can find it any time, alongside all the site's resources offered for free.

Frequently asked questions
What percentage should I risk on a position?
The convention is 1–2% of the account, as a ceiling. What matters is that the percentage stays the same on every position, regardless of style or how often you trade — whether you make 20 trades a day, one after another, or 2 a week, you put the same percentage on each. What differs between scalping and swing trading isn't the percentage, but the volume: scalping has a tight stop, so a larger volume; swing trading has a wide stop, so a smaller volume, at the same risk. Frequency is managed separately, through the total exposure limit (chapter 10), not by changing the base percentage.
Can I trade without a stop-loss?
Technically yes, but on leveraged instruments it means a loss with no preset limit. At regulated brokers, negative balance protection saves you from losing more than you deposited — but it doesn't protect your deposit.
What leverage is "safe"?
Leverage isn't safe or unsafe in itself. The risk comes from position size, not from the available leverage. You can use high leverage with a small position and risk little, or the other way around. The figure that matters is the percentage of the account you risk.
How many positions can I have open at once?
It's not the number that matters, but total exposure and correlation. Five correlated positions can be riskier than ten uncorrelated ones. Limit the combined exposure in a single direction.
Does risk management guarantee profit?
No. It guarantees that a single mistake doesn't close your account. Profit comes from the system's edge plus discipline; risk management only keeps you in the game long enough for the edge to matter.
