Copy trading links your account to another trader’s decisions. When the selected strategy opens, changes or closes a position, the platform can make a corresponding trade on your account. The details matter: copying a trade is not the same as owning a managed fund, buying a trading signal or buying an AI model.
The four participants in a copy trade
There is usually a strategy provider, a copier, a technology layer and a brokerage or trading account. The provider chooses trades. The copying technology mirrors qualifying positions using its sizing rules. The broker executes trades and holds the relevant account balance under its own terms.
A product such as TAG CopyX sits within the TAG Markets environment. cTrader Copy is a copying component used through participating brokers. eToro CopyTrader is offered within eToro. These product boundaries can affect your fees, investor protections and available instruments.
Why your results can differ from the provider’s
Execution happens in a separate account, possibly at a different moment or price. Spreads, slippage, leverage, minimum order size, available cash and different start dates change the resulting returns. A provider’s past performance chart is therefore not your expected return.
Sizing also varies. Some systems calculate copied volume from the ratio between provider and copier equity; others let you set a fixed amount or a percentage of your account. Read the actual formula before you fund an account.
Five checks before selecting a strategy
Look beyond percentage return and follower counts. A strategy that has never experienced a difficult market cannot prove its ability to survive one.
- Maximum historical drawdown and whether that figure includes open positions.
- Trading history length, missing periods and independently verifiable account data.
- Leverage, concentration, average holding period and use of stop losses.
- Provider fee, platform fee, spreads, commissions, swaps and withdrawal charges.
- Ability to pause copying, set an equity stop or exit without waiting for the provider.
What copy trading does not do
It does not transfer investment responsibility away from the account holder. It does not eliminate losses and it does not guarantee diversification: several apparently different providers may all hold the same currency or gold exposure.
If the underlying trades are leveraged CFDs, you face market and leverage risk as well as provider-selection risk. The broker entity and customer safeguards vary by country. Always check which legal entity would actually open your account.
A safer research process
Begin with the product and legal entity, not the headline return. Read account terms, verify whether the platform accepts residents of your country, examine the full available performance history, calculate a plausible worst-case account loss and understand how to stop copying. A demonstration account, where available, can help you learn the interface but cannot reproduce every live-market condition.
