What it is
Copy trading is a feature offered by certain trading platforms that lets you automatically replicate the trades of another trader — the "signal provider" — in real time on your own account. When the signal provider opens a trade, the same trade opens proportionally on your account. When they close it, yours closes too.
Popular copy trading platforms include eToro, ZuluTrade, and Myfxbook's AutoTrade feature. MetaTrader's MQL5.community also offers signal copying natively within the platform.
How it works
- You choose a signal provider from the platform's list — typically choosing based on their track record, drawdown history, and trading style
- You set your allocation — how much of your account you want to mirror (usually as a percentage or a fixed amount)
- The platform automatically opens and closes the same trades on your account, scaled proportionally to your allocation
- You can stop copying at any time
The signal provider receives a fee — either a flat monthly subscription or a percentage of the profits they generate for copiers.
Copy trading vs Expert Advisors
- Copy trading: You replicate a human trader's live decisions in real time. The strategy depends on the individual trader continuing to perform.
- Expert Advisors: You run a rule-based automated strategy directly on your account. No reliance on a third party continuing to trade. More control over configuration.
Both approaches automate the execution of trades. The difference is where the trading decisions come from — a human signal provider vs a programmed algorithm.
Risks specific to copy trading
- You are dependent on the signal provider continuing to trade well — past performance doesn't predict future results
- The signal provider may change their risk approach without warning
- Execution slippage between the provider's trade and your copied trade can affect results
- The best signal providers often have capacity limits — their performance may degrade as more copiers follow them
Common misconceptions
- A high-performing signal provider is not guaranteed to keep performing. Selection bias is severe in copy trading — you see the survivors. Many poorly performing providers are not prominently listed.
- Your account is still your own. Copy trading does not mean the signal provider has access to your account. They trade their own account, and the platform mirrors those trades on yours. Your capital stays with your broker.
