What Copy Trading Is
Copy trading is an arrangement in which the trades of another account, called the signal provider, are reproduced in your own trading account automatically, usually within seconds. Your money stays in your account, at your broker, in your name. What you hand over is the decision about what to trade, when, and how much.
The Robotic Trader's view: copy trading is a legitimate mechanism, but it moves the whole question of risk onto one choice, the provider you follow, so that provider deserves the same scrutiny as any Expert Advisor you would buy.
How the Copying Actually Works
Three parties are involved: the provider's account, the copy service that reads it, and your own account at your broker. When the provider opens a position, the service sends a matching instruction to your account, and your broker fills it at its own price.
Sizing is proportional, not identical. On MetaTrader 5's built-in Signals service, for example, you choose what percentage of your deposit the copied trades may use, and the platform calculates each copied volume in proportion. You can also set an equity level at which copying stops and every copied position is closed, and a maximum price deviation, measured in spreads, beyond which a trade is not copied.
That is why your results never match the provider's exactly. Your fills come at your broker's prices, volumes are rounded to your broker's lot sizes, and a symbol may be named or priced differently. Where the minimum and maximum lot sizes on the two accounts differ, MetaQuotes warns that "there can be serious difference in volume" between the provider's trades and yours.

The worked arithmetic, with examples, is in how copy trading actually works: lot sizing and proportional copying.
The Main Ways to Copy
Built into the platform
MetaTrader's own Signals service. You subscribe from inside the terminal, trades are copied to your account at your own broker, and the provider's statistics are published on MQL5.
Third-party copy networks
An independent platform connects providers to a list of supported brokers and passes their signals to your account. You are limited to the brokers it supports, and each network sets its own fees and rules.
Broker-run copy services
Some brokers run copy trading inside their own platform. Provider and follower must both trade at that broker, so your choice of provider is limited to that broker's community.
Trade copiers you run yourself
Software that mirrors one account you control onto another, such as a MetaTrader trade copier. It is a tool for copying between your own accounts, not for following other people.
The model you choose changes who you depend on, what you pay and how easily you can leave. It does not change where most of the risk sits, which is with the provider.
What It Really Costs
- The provider's fee. On MetaTrader's Signals service it is a monthly subscription, and some signals are free; on other platforms it may be a share of profits.
- The platform's take, which may be a separate fee, a charge per lot or a mark-up built into the spread. Check which before you start.
- Your broker's normal costs: spread, commission and overnight swap on every copied trade.
- Divergence: the gap between the provider's fills and yours, which is a cost even though nobody invoices it.
Before subscribing, find out how the provider and the platform are paid. If either earns more when you trade more, that is worth knowing. The full breakdown is in copy trading fees explained.
Where the Risk Sits
- The provider's bad month. Losses are copied as faithfully as gains, so the provider's worst month becomes yours.
- Hidden structure. Systems that add to losing positions, such as grid and martingale recovery, can show a smooth equity curve for a long time and then give it all back. The signature is lot sizes that grow after losses.
- Short or selected records. A few good months, a demo account, screenshots, or a provider showing one account while others failed elsewhere.
- Execution divergence. Your fills differ from the provider's, and on fast scalping strategies the difference can decide whether the strategy works for you at all.
- The provider stops. Signals get withdrawn and accounts get closed. Positions already copied can stay open in your account, and managing them falls to you.
- Your own settings. The share of your deposit you allocate and your account's leverage decide how hard each loss lands.
How to Check a Provider Before You Follow
- How the record is verified. A third party reading the account directly, such as Myfxbook, FXBlue, Show My Trades or MQL5, is evidence. The copy platform's own page, screenshots and demo accounts are not.
- How long, and how many trades. Months of real-money history and the number of closed trades. For the Expert Advisors we review, we require at least 12 months and 300 closed trades, and 24 months for a Recommended verdict; see how we test.
- Maximum drawdown, disclosed. Ideally both the balance and the equity figure, because the equity figure shows the open losses the balance figure hides.
- Profit factor beside the win rate. A high win rate on its own means nothing if the losses are several times the size of the wins.
- Stop losses on every trade. A record with no stops can look perfect until the one trade that isn't.
- Lot sizes after losses. If they increase, you are looking at a recovery system, whatever the description says.
- Deposits and withdrawals. Money added during a drawdown flatters every growth figure that follows.
- Who the provider is. A registered business, a named individual, or a username with nothing behind it.
Copy Trading or Your Own Expert Advisor?
Copy trading hands the decisions to a person or system you cannot inspect. Running your own Expert Advisor puts the system on your own account, where you can test it and set its risk yourself, at the cost of setup and maintenance. We set out both sides in copy trading versus running your own EA, and publish every verdict we have reached on the Expert Advisors we have reviewed.
Trading a funded account? Prop firms have their own rules on copying, covered in copy trading inside a prop firm account.
Our Position
The Robotic Trader does not offer copy trading and does not recommend any copy-trading provider or platform. There are no affiliate links on this page.
We run real-money accounts of our own only on Expert Advisors that have passed our full testing standard. Each is published in full, drawdowns included, on that Expert Advisor's review, and none is offered for copying. Current verdicts are on our Expert Advisor reviews.
Frequently Asked Questions
What is copy trading?
Copy trading reproduces another trader's positions in your own account automatically, in proportion to the share of your deposit you allocate. Your money stays at your broker, in your name; what you hand over is the trading decisions.
Is copy trading legit?
As a mechanism, yes: copying is built into MetaTrader itself and offered by brokers and independent platforms. The risk is in who you copy. Treat any provider with only screenshots, a demo account or a short record with caution, and never give a provider your account password or send them money directly.
Is copy trading profitable?
It is exactly as profitable as the provider you follow, less the fees and the divergence between their fills and yours. There is no honest general figure. Judge each provider on the length of the real-money record, the maximum drawdown and the profit factor, not on headline growth.
How do I start copy trading?
Choose a broker, choose how you will copy (MetaTrader's built-in Signals, a copy network or your broker's own service), check the provider against the eight points above, then set the share of your deposit you will allocate and a level at which copying stops. Start small, and compare your results with the provider's for the first month.
If you are still choosing a broker, see our MT5 broker comparison.
Is copy trading good for beginners?
It removes the need to make trading decisions, but not the need to understand risk. A beginner still has to judge the provider, and that is the hard part. Run any provider through the signal provider scorer above before committing money.
Does The Robotic Trader offer copy trading?
No. The Robotic Trader does not offer copy trading, recommend a provider or earn anything from copy trading. Where we run an Expert Advisor that has passed our full testing standard on a real-money account, the account is published in full on that Expert Advisor's review, and it is not offered for copying.
Risk Disclosure
Trading Forex and CFDs carries a high level of risk to your capital and you should only trade with money you can afford to lose. Past performance of any trading system or methodology is not necessarily indicative of future results.
Copy trading automatically mirrors another trader's positions in your own account, so their losses reach your account as well as their gains. Please ensure you fully understand the risks involved, the mechanics of copy trading, and your own risk tolerance before participating. It is worth knowing in advance what a bad month actually looks like when you are copying someone else's trades.
