Copy trading is a form of trading in which the trades of one account, the master or signal provider, are automatically copied to one or more follower accounts. When the master opens, modifies or closes a position, the same happens on the follower accounts, scaled to each follower's account size and risk settings. Copy trading is popular in forex, CFDs and crypto, and is offered by social trading platforms, brokers and dedicated copy trading software.
How does copy trading work?
- Trade capture: the copier detects every new order, modification and close on the master account, via the trading platform or broker API.
- Distribution: the trade is sent to all followers within milliseconds to seconds.
- Lot sizing: each follower's position size is calculated, for example as a fixed lot, proportional to account equity, or with a multiplier.
- Risk controls: per-follower limits such as maximum lot size, maximum open positions, symbol filters and drawdown stops.
- Reporting: results per master and per follower, and often performance fees or subscriptions for the provider.
Copy trading, social trading and signals
Social trading platforms combine copy trading with profiles, rankings and discussions, so followers can choose whom to copy. Trading signals are a looser form: the provider publishes trade ideas, and the subscriber executes them manually or with an Expert Advisor. With copy trading, execution is fully automatic. Within MetaTrader, copy trading also happens between a trader's own accounts, for example to run one strategy on several accounts or brokers at once.
Risks and points of attention
Followers copy losses just as faithfully as profits, and past results of a master are no guarantee for the future. Differences in broker, spread and execution speed mean follower results never exactly match the master's. Many prop firms restrict copy trading between accounts. And in the EU, offering copy trading to others can fall under financial regulation, depending on how it is set up; get advice from a regulatory specialist before launching a service.
Copy trading software
Brokers, signal providers and fund managers often need more than an off-the-shelf copier: their own branding, multiple platforms (MT4, MT5, cTrader), specific allocation rules, subscriber management and billing. See our copy trading software, signal provider tools and what is algorithmic trading.
Frequently Asked Questions about Copy Trading
Is copy trading profitable?
It depends entirely on the trader being copied, the costs and the risk settings. Copy trading automates execution; it doesn't remove market risk. Be wary of providers who promise guaranteed returns.
Is copy trading legal?
Yes, copy trading itself is legal. Offering it to others as a service can, depending on the setup, be regulated as portfolio management or investment advice, so providers should have their structure reviewed.
Can trades be copied between different brokers?
Yes. A trade copier can connect accounts at different brokers and platforms, translating symbol names, contract sizes and lot steps where they differ.
How fast is copy trading?
A well-built local or server-based copier copies trades within milliseconds to about a second. Cloud copiers that poll accounts are slower, which can matter for short-term strategies.
