The Ultimate Guide to Copy Trading on Polymarket
Finding a profitable wallet is the easy half. This walks through picking one worth following, then setting the sizing, filters and limits that decide what copy trading actually costs you.
Copy trading gets sold as a shortcut. Find someone who wins, mirror their trades, collect. The part nobody puts on the poster: you do not have their bankroll, their exit discipline, or their reason for taking the position in the first place. Copying every move they make is how you inherit their risk without their plan.
What works is narrower. Pick a trader you understand, then decide which of their trades you want and how much of your money goes behind each one. Kreo is the bot most people on Polymarket use for this, and its settings are where the whole thing lives or dies. This walkthrough follows the setup end to end, using the screenshots from the Kreo team's own guide.

Finding wallets worth copying
Start on the Polymarket leaderboard. It ranks by profit, which is the wrong number to copy on its own. A wallet can sit near the top on one lucky resolution.
What you want is consistency. Before you copy anyone, look at:
- profit and loss over time, not one spike
- volume traded and number of trades
- which markets they trade
- how often they trade
- win rate
Paste any wallet address into Kreo on Telegram and it returns that profile for you.
Letting AI Match build the shortlist
Reading wallets by hand is slow. Kreo's AI Match takes your constraints and returns candidates instead.
You tell it your risk tolerance, the markets you care about, your trading style, how long you want to hold, how active the trader should be, and what should weigh most in the ranking.
Treat the output as a shortlist, not a verdict. Check the wallets yourself before any money follows them.
Setting up the task
New accounts run /start first, which creates the trading wallets, then fund the one you plan to trade from. For Polymarket that means USDC.e on Polygon for direct deposits, with bridging available inside Kreo. Check the network and the asset before you send anything.
Then open /copytrade and press Add Task.
Kreo asks for the wallet, either a Polymarket username or the address. Give the task a name you will recognise later, pick which Kreo wallet places the trades, and you are at the question that matters most: how much of your money follows each trade.
Four ways to size a copied trade
Fixed spends the same amount every time. Ten dollars a trade, whatever the trader does. It is the easiest thing to reason about.
Exact matches their dollar amount. They buy $100, you buy $100. Risky when their bankroll dwarfs yours.
Percentage takes a share of their position. They buy $100, your setting is 10%, you buy $10. Your size moves with theirs.
Portfolio weighted looks at what share of their portfolio the trade represents and applies a similar share of yours.
If you are new, start on Fixed. You know exactly what each trade costs you. Move to Percentage or Portfolio weighted once you have watched the strategy run for a while.
Max Buy, your first safety rail
Max Buy caps what a single trade can spend. It matters most with Percentage sizing: your trades might be running at $15, then the trader drops $5,000 on something and your calculation jumps with them. A $20 Max Buy stops that at $20. There is a Min Buy too, which sets a floor.
Deciding which trades you want
This is where copy trading stops being blind. You do not have to take everything the wallet does. Kreo filters on category, market name, trade size, liquidity, volume, market expiry and price.
The difference is between "follow every move this trader makes" and "follow this trader in the markets I understand".
Copy a trader's specialty, ignore the rest
Say the wallet is excellent on crypto and also trades sports, politics and economics. You want the crypto.
Select Crypto in Categories and the rest of their book never triggers your task. For most people this single setting is the biggest improvement they make.
Trigger Range: ignore the very small and the very large
Trigger Range filters on what the trader spends. Set a $25 minimum and a $500 maximum and a $2 test trade will not pull you in, nor will a sudden $10,000 swing.
Price range
Polymarket contracts run from one cent to a dollar. A 10c to 90c range keeps you out of the lottery tickets at both ends.
Liquidity is not optional
Your trader might get a clean fill where you will not. Copy a large trade into a thin market and you move the price against yourself. Kreo lets you require minimum liquidity and volume, and a copied trade is only worth having if you can get filled at a sane price.
Slippage
The trader buys at 45c, you get filled at 49c. Same market, different price. Kreo defaults to 5% and you can change it: more room means more fills, less room means better prices and more misses.
What happens when they buy and when they sell
Follow Buys does what it says. Copy Sells makes their exits yours as well, which matters more than people expect. Counter Trade inverts them: they buy YES, you buy NO. That is not copy trading any more, that is betting against a wallet you are watching.
Price Match Mode
A copy trade normally fills at whatever the market shows when your order lands. Price Match Mode places a limit order near the price the trader got instead.
They filled at 42c, you try for 42c. Better control over your entry, fewer fills.
Spending limits beyond a single trade
Max Spend, Daily Cap, Per Market, One Entry per Market. Set Max Buy at $10, Daily Cap at $50 and Per Market at $20, and a trader having a busy day cannot drain the wallet.
Global One Entry per Market earns its place when you copy several wallets at once. Three traders piling into the same Bitcoin market is not three independent bets, and without the global limit you would enter it three times.
Stop loss and take profit
You are not obliged to hold to resolution. Kreo does stop loss, take profit, and layered exits: sell half at +20%, the rest at +50%, in percentage, fixed price, or layers.
Do not add one because the field exists. If the wallet you copy holds to resolution, a tight stop loss turns their strategy into a different one.
Normal or Priority monitoring
Normal is standard. Priority detects trades faster and is what Kreo recommends for active traders.
The whole loop, in order
- Find traders on the leaderboard, in external tools, or through AI Match.
- Research them: what they trade and how, from the wallet profile.
- Shortlist the ones whose strategy you can explain to someone else.
- Add each as a copy trading task in Kreo.
- Start small on Fixed sizing.
- Add filters: categories, price, liquidity, trigger range.
- Add limits: Max Buy, Daily Cap, Per Market.
- Watch the Activity menu, the skipped trades as much as the taken ones.
- Adjust the settings against what you see.
- Scale only once you know what the strategy is doing.
The order is the point. People who lose money copy trading usually did steps one and four and skipped everything in between.
