What Is Copy Trading? How It Works and What to Watch For
Copy trading means automatically or manually copying the trades of another trader or wallet in your own account. It saves research time but copies their mistakes too, and prices, fees and timing mean your results will differ from theirs. Start small and know who you are copying.
Copy trading, defined
Your account follows trades another trader or wallet already placed. You choose who to follow and how much money is in the copy. When they buy or sell, you get a version of that trade, on its own or after you confirm. The position, the fees, and any loss stay with you.
The IOSCO final report on copy trading (FR/06/2025) calls this an online imitative trading practice: a copy trader copies trades of one or more lead traders, often automatically, though other models exist. It shows up in short-term markets, including foreign exchange and crypto-assets.
The Investor.gov glossary says certain digital platforms enable investors to copy the trades of other investors, known as copy trading, in certain types of investments.
The lead trader places the trade. The copier supplies the money. Following them does not make them your adviser. Copying can be automatic, rule based, or by hand, and your fill is not their fill. Broker pages often mean foreign exchange or contracts for difference. In crypto the source is often a public wallet. More guides are on the Learn hub.
Copy trading vs mirror trading vs social trading
IOSCO treats copy trading, mirror trading, and social trading as related practices with different automation. Mirror trading copies every trade of one leader automatically, so you do not pick trade by trade. An algorithm can send the signals. Social trading is generally not automated: people share ideas, and you decide whether to trade. A post is not a fill.
Onchain wallet copying follows a public address with no agreement from the owner. AI agent copying reads the wallet and the token, then buys, skips, or asks you. The table maps the trigger. It does not rank results.
| Type | What is copied | How automatic | Link to the source |
|---|---|---|---|
| Copy trading | Some or all trades, by a fixed amount or a portion of your balance | Often automatic; you may confirm or copy only part | A lead trader on a platform |
| Mirror trading | Every trade of one leader or strategy | Automatic | The account mirrors the whole stream |
| Social trading | Ideas and trades people discuss | Usually manual | A community, not an order router |
| Onchain wallet copying | Buys and sells of a public wallet | Manual, or an app you choose | No agreement with the owner |
| AI agent copying | Trades the agent accepts after reading the wallet and the token | Buys, skips, or asks you | You set limits; the agent is not that wallet |
How copy trading works, step by step
Screens differ. The steps below are the usual order, and they are not tied to one broker.
- Pick a trader or a wallet. Read how long the record runs and how large the drops were, not only the headline gain.
- Set an allocation. Assign a fixed amount or a portion of the account. Start small.
- Trades are copied. The platform can send the order when the leader does, or it can wait for you. Rule based copying can skip trades or cap size.
- You pay fees. That may be a spread, a commission, a performance fee, a subscription, or a fee on each swap. Frequent trading multiplies it. IOSCO warns that transaction fees from frequent trading may erode gains or extend losses.
- You can stop. Ending the link should stop new copies. Positions already open may stay open. Test that stop while the size is still small.
You will not match the leader. You enter later, your size differs, and slippage plus fees come out of your account. Before you start, confirm if copying is automatic, if you can cap or skip a trade, how the leader is paid, the fee per trade, and what open positions do when you stop.
Onchain copy trading: following public wallets
On Solana, any wallet is public. Its buys and sells can be read by anyone. A Solana wallet tracker watches addresses so you do not have to refresh an explorer. The owner did not agree to be a lead trader. There is no contract with you, and no duty to say when the strategy, a hedge, or the size changes. The address might be a treasury, a market maker, or a bot.
You arrive second. A crowd copying the same wallet can move the price against you, and that wallet may already be selling while your buy lands.
Copy trading in the Moby app follows this pattern and covers Solana tokens only. The Moby app itself supports Solana, Robinhood Chain, BNB Chain, and Base for trades you place yourself.
When an AI agent does the copying
An agent can sit between you and the wallet. It reads the wallet's record and the token, then buys, skips, or asks you. A copy trading agent is not a mirror of every fill. It can still follow a bad wallet or arrive late. Watching large wallets rather than one leader you chose is whale tracking.
You set your agent's limits on max per trade, daily buy volume and market-cap range from the Moby app, and Moby checks them server-side on every buy your agent makes. The longer write-up is AI agent guardrails.
Risks of copy trading
IOSCO lists harms that apply whether you copy a person, a strategy, or a wallet.
- Timing and pricing. Followers of a popular leader can move the price, so copiers buy higher or sell lower than the leader.
- Strategy changes. A leader can switch markets or products with no notice. A public wallet never promised a style.
- Conflicts. Pay tied to volume, signups, or a product can work against the copier. Ask how the leader is paid.
- Fees from frequent trading. A busy record can still shrink the account. Small sizes feel a per-trade fee first.
- Operational risk. Outages, bad data, or a security incident can copy a trade you did not want, or miss the exit. Algorithm flaws count too.
- Survivorship bias in leaderboards. Boards show who is still listed, often sorted by a recent gain. People who stopped or lost the account drop out of view. A top row is not the average result.

Is copy trading legal? Is it profitable?
Is copy trading legal?
It is a common feature on regulated platforms. Every offer is not automatically allowed, and a leader is not automatically licensed. IOSCO says firms should check whether the service is investment advice, portfolio management, or another activity that needs registration. Check the platform's terms and your local rules before you start.
Is copy trading profitable?
It can lose money as easily as make it. IOSCO notes that copying is often marketed as simple and profitable when the product is complex. A profit promise is a red flag.
Can I make $1000 per day from trading?
No. Copy trading is not a wage. A promise of $1000 a day with little risk is a sales line, not a feature of the tool.
How much money do I need for copy trading?
Platforms set their own minimums. Fees take a larger portion of a small trade, so read the fee first and start with money you can afford to lose.
How to choose who to copy
A checklist does not remove the risk. It does block a decision based only on a short screenshot.
- A long record, including quiet months, not a few good days.
- Drawdowns. Find the worst drop, and see if the style changed afterward.
- Trade size. A small trade for them can be your whole allocation. Keep a cap.
- Consistency of markets and holding time, at a pace whose fees you can pay.
- Incentives. Paid to be copied, or a public wallet that never agreed.
- A way out that stops new copies, plus clarity on positions already open.
If an agent will send the orders, read risk management for AI trading before you raise size. Tool roundups are on the Best hub. This page does not score platforms.
Frequently asked questions
What is copy trading?
Copy trading means copying the trades of another trader or wallet into your own account, either automatically or by hand. You keep control of your money, but your results depend on the trader you copy, plus fees and timing.
Is copy trading profitable?
It can lose money as easily as make it. Past results of a leader do not predict future results, and fees and slippage mean your returns differ from theirs. Treat any profit promise as a red flag.
Is copy trading legal?
Copy trading itself is a common feature on regulated platforms, but rules depend on where you live and the platform you use. Check the platform's terms and your local rules before you start.
How much money do I need for copy trading?
Many platforms set a minimum, and fees per trade matter more on small sizes. Start with an amount you can afford to lose and check the fee per trade first.
What is the difference between copy trading and mirror trading?
Mirror trading copies every trade of a chosen leader automatically. Copy trading can be partial or rule based, and social trading usually means sharing ideas with no automatic copying.
Can an AI agent do copy trading?
Yes. An AI agent can watch wallets you choose, check each trade and token, and buy within limits you set or ask you first. It does not remove copy trading risk, so keep sizes small.
