Copy trading is a way of trading in which your account automatically repeats the trades of another trader. When that person opens a position, sets a stop loss or closes a trade, the same thing happens in your account, scaled to the amount you chose to allocate. It can look like an easy shortcut for beginners, but it hands your decisions to someone you usually do not know, so it carries real risk. This guide explains how it works, what it costs, where it can go wrong and how to judge an offer.
In brief
- Copy trading links part of your funds to a chosen trader, and each of that trader's moves is repeated in your account in proportion.
- You usually keep control of how much you allocate and can stop copying, but the results depend on someone else's decisions and skill.
- Past results of a trader do not predict future ones, and platforms tend to show their most successful traders, so rankings can mislead.
- In crypto, price swings and leverage can make losses large and fast, so a copied trader's style matters as much as their headline result.
- Before you copy anyone, check who runs the platform, what every fee is and how much you could lose, and only use money you can afford to lose.

What copy trading is
A study published in Management Science in December 2020 describes the mechanics: copying another investor means dedicating a share of your budget to follow that person's trades, and once you copy them, all their trades are replicated for you as they happen, in proportion to your budget. If the leader puts 1% of their portfolio into a trade, so do you. Copy trading is often distinguished from mirror trading, where you follow a strategy rather than a person.
The trader being copied is often called a leader or a signal provider, and the person copying is the follower. In a briefing for supervisors published on 30 March 2023, the European Securities and Markets Authority (ESMA) describes copy trading as a service that involves trading a client's assets based on the trades of another trader, and notes that the trading is usually automated. Terms vary between platforms and sources, so always read how a given service defines what it does.
How copy trading works, step by step
The details change from one platform to another, but the typical flow is similar:
- You open an account on a platform or exchange that offers the feature and secure it with a strong password and two-factor authentication.
- You browse the available traders. Platforms usually show a profile with past results, the assets traded, how long the trader has been active and sometimes a risk indicator.
- You choose an amount to allocate. Only this part of your funds is linked to the trader you copy.
- Trades are mirrored. When the leader opens, changes or closes a position, your account does the same in proportion.
- You review and adjust. As the Management Science study describes, you can usually stop copying a leader at any time: the relationship ends and all copied positions are closed at the current market price.
Mirroring is rarely perfect. Orders reach the market a moment after the leader's and can be filled at slightly different prices, and a small allocation may not allow the exact same position sizes. These differences are usually small, but they can add up in fast or thinly traded markets.
What copy trading costs
Costs depend on the service and are worth reading before you start. According to the same study, most platforms reward investors for being copied, for example with a commission on the volume their copiers trade, fixed payments or rebates on the spread, which is the gap between the buy and sell price. It adds that these platforms typically earn their own revenue from the spread rather than from subscription fees, so they have an interest in high trading volume. The briefing from ESMA also points to the information firms should give about costs and charges and about how leaders are rewarded, because those payments can create conflicts of interest.
In practice, look for these items: spreads and trading commissions, any fee charged by the platform, any fee or share of profit paid to the leader, funding costs on leveraged positions and withdrawal fees. Write them down next to the amount you plan to allocate, because costs reduce results whether the copied trader wins or loses. Prices and fees change, so check the current terms on the platform itself.
How it compares with other ways to trade
| Copy trading | Trading signals | Trading bot | Trading on your own | |
|---|---|---|---|---|
| Who decides the trades | A trader you choose | A provider, then you | Rules and settings | You |
| Are orders placed automatically | Usually yes | Usually you place them | Usually yes | No |
| What you control | Amount, which trader, when to stop | Whether to follow each signal | Settings and filters | Everything |
| Main risk | The trader's decisions and style | Signal quality and your timing | Poorly set rules or a weak strategy | Your own mistakes and emotions |
None of these removes the risk of loss. They differ in who makes the decisions and how much work is left to you. To compare the two automated options, you can read our guide to the crypto trading bot.
The advantages of copy trading
- A way to learn. You can watch how a more experienced trader sizes positions, uses stop losses and handles losing streaks. A guide to the stop loss and take profit orders helps you recognise what you see.
- Less time at the screen. Once trades are mirrored, you do not have to watch the market all day.
- Lower barrier to start. Many platforms accept small allocations, so you can begin with a limited amount.
- Visible track records. Most platforms show a trader's history, which is more than you get from many tips on social media, as long as you read it critically.
- Control kept. You usually choose the amount, the trader and the moment to stop.
The limits and risks of copy trading
The risks are the other half of the picture, and they are not small.
- Past results are not a promise. A good year can end quickly, and a trader can change style when conditions change. Platforms often promote traders who did well, which creates a selection effect: what you see is not a fair sample of all traders.
- It can push people to take more risk. A study by Apesteguia, Oechssler and Weidenholzer, published in Management Science in December 2020, used an experimental asset market and found that showing the success of others raised risk taking, and that the option to copy directly raised it further. In the second round of the experiment, about 32.5% of participants picked the riskiest of four assets when they saw nobody else's results, and 47.9% when they could see the past results of others. Where copying was possible, 65% either picked that asset themselves or copied someone who had. The authors concluded that copy trading leads to excessive risk taking.
- Leaders are not always supervised. Depending on the platform and region, the people you copy may not be professionals or regulated advisers. A reliable track record, a stop loss and a stated maximum drawdown, meaning the largest fall from a peak, tell you more than a headline percentage.
- Leverage multiplies losses. If the leader uses borrowed money to trade, your account is exposed to the same effect. Our guide to leverage in crypto trading explains why this can wipe out an allocation.
- Crypto adds its own risks. The European supervisory authorities warn that many crypto-assets are highly risky and speculative, that you may lose all the money you invest and that prices can rise and fall quickly. They also warn about misleading advertising on social media and about promised fast or high returns that look too good to be true.
- Scams use the same words. The US Commodity Futures Trading Commission (CFTC) has described fraudsters who advertise automated trading and signal schemes with unreasonably high promised returns. A real copy service does not need to promise results.
How to choose a trader and a platform
Choosing is the part you control, so take it slowly:
- Check the platform first. See whether the company is authorised by a financial regulator where you live and whether it appears on warning lists. Regulators warn that dealing with unauthorised firms carries high risks of losing capital because they operate outside supervisory controls.
- Read the track record over time. Prefer a long history that includes a bad period over a few spectacular months. Over our years of trading and investing, we have learned to read the worst stretch of a record before the best one: it shows how a trader handles risk when things go wrong.
- Look at the maximum drawdown, not only the profit. A trader who lost a large part of the account once could do it again.
- Check the instruments and the leverage the trader uses, and whether that matches the risk you accept.
- Understand how the leader is paid. A trader paid for each trade or for the number of followers may have different incentives from one paid on results.
- Spread your allocation. Copying several traders with different styles reduces the effect of one failure, though it does not remove risk.
Be wary of anyone who contacts you privately, asks you to move money to an unknown platform or promises regular gains. These are classic warning signs of a scam.
John Bax's view
In Lazy Investor, Smart Investor, John Bax treats copying a "master trader" as one of the lazier alternatives to day trading, with a few practical rules: choose someone with a strong reputation, and allow at least a few months before you judge the results or switch. He also notes that you can expect a one-time follower fee plus a share of profits, often 10% to 30%, and that many master traders suggest $1,000 to $2,000 to copy them properly. Fees and minimums vary from one platform to another, and the book is clear that copy trading does not guarantee profits.
Where Crypto Go Bot fits
Crypto Go Bot, which we built, is not copy trading in the strict sense, because it does not mirror one person's account. Every hour it receives the Crypto Go Smart Money Flow, our own reading of the money entering and leaving wallets of investors with a proven track record, graded Low, Medium or Strong. You choose the minimum strength, the token size and the blockchains to follow, and the bot opens and closes positions on your own Kraken account through a Futures trading API key (an application programming interface key that lets software place orders for you) that you create. It cannot withdraw funds, and take profit and stop loss orders are placed on Kraken.
Copying one person is not the only way to follow other market participants: some investors watch what the largest wallets do on public blockchains, as this Bloomberg explainer shows.
What Bitcoin whales are and why investors watch them (Bloomberg) (in English)
For someone who likes the idea of delegating the work but wants rules they can see and change, that is a different approach with its own risks. The bot also closes trades at a loss, and no system can guarantee profits. You can read the full overview in our article on the crypto trading bot.
How to start, step by step
- Learn the basics first. Understand long, short, leverage and stop loss before you let anyone trade for you.
- Choose a platform you can verify. Check its authorisation, fees and how you can withdraw your funds.
- Start with a small allocation that you can afford to lose completely.
- Pick one or two traders after reading their full history and their drawdown.
- Set limits. If the platform allows it, use a maximum loss on your allocation.
- Review on a schedule, for example every week, and stop copying if the style changes or you no longer understand it.
Checklist before you copy anyone
- I know who runs the platform and how it is authorised.
- I have read every fee and how the leader is paid.
- I have checked the trader's history over a long period and the biggest fall.
- I know whether leverage is used and what it can do to my allocation.
- My allocation is money I can afford to lose.
- I know how to stop copying and close positions.
If you prefer to understand the wider picture first, our book Lazy Investor, Smart Investor has a part on lazier alternatives to day trading, including trading signals, copy trading and bots, and explains why day trading is hard for people who do not want to spend hours on it.
Who it is for
Copy trading suits people who want exposure to active trading without placing every trade themselves, and who accept that someone else's decisions will drive their results.
- Beginners who want to learn by watching: with a small allocation they can afford to lose, they can see how an experienced trader sizes positions and uses stop losses, as long as they first learn what leverage and drawdown mean.
- Busy people with little screen time: they can let trades run while they work, provided they review the copied account every week or two and know how to stop copying.
- Active traders who want to diversify their own style: they can copy one or two traders with a different approach next to their own trading, keeping the copied part small.
- Patient followers with a long view: people ready to give a trader several months before judging, and to accept losing streaks along the way, are better suited than those who switch after one bad week.
Key terms
- Leader: the trader whose positions are copied, sometimes called a signal provider or master trader.
- Follower: the person whose account repeats the leader's trades.
- Allocation: the part of your funds you link to a leader, and the most you can lose by copying them.
- Drawdown: the fall of an account from its highest point to its next low, often shown as a percentage.
- Spread: the gap between the buy and the sell price, a cost paid on every trade.
- Mirror trading: copying a trading strategy or system rather than a specific person.
Frequently asked questions
Is copy trading the same as mirror trading?
Not exactly. Mirror trading usually means copying a strategy, while copy trading links part of your funds to a person and repeats that person's trades. Some sources use the two terms differently, so check how a platform describes its service.
Can I lose money with copy trading?
Yes. The trades in your account can lose money just like any other trade, and you can lose the whole amount you allocate. A trader's earlier results do not guarantee what happens next.
Is copy trading good for beginners?
It can help beginners learn by watching how experienced traders behave, but it is not an easy shortcut. A beginner still needs to understand leverage, drawdown and the costs, because they are the ones who bear the losses.
Do I pay the trader I copy?
It depends on the platform. Leaders are often rewarded by the platform itself, through commissions, fixed payments or spread rebates, and some services also charge followers a fee or a share of profits. Read the fee page before you start and ask how the leader earns.
Is copy trading legal and regulated?
Rules differ between regions, and the status of a service can depend on how it is built. In the European briefing mentioned above, ESMA says that automatic execution of another trader's trades can fall under portfolio management. Always check whether the firm you use is authorised where you live.
How much money should I start with?
Only an amount you could lose without harm to your life. A small allocation lets you see how the service behaves, how costs add up and how you feel when the account falls, before you decide whether to continue.
