If you want to choose Polymarket traders to copy, start by finding wallets whose trades you could realistically follow. A large profit number is useful context, but you also need to understand trade frequency, typical size, losses, and the markets behind the result.

PredScout puts these checks in the Smart Traders leaderboard and each trader profile. The steps below help you turn a long list into a small set of Paper-mode candidates.

Trader profiles, a magnifying glass and comparison notes illustrate choosing Polymarket traders beyond headline profit.

1. Compare the same time period

Choose 30D, 90D, or All on the leaderboard. Use the same period for each wallet. Look at P&L, which means profit and loss, alongside P&L / Buy Amount and Trades. One winning event can make a short period look exceptional; a longer period shows whether a trader kept participating.

Check when the wallet last traded. If it has gone quiet, there may be nothing new for a copy strategy to follow. Recent activity alone is not proof of skill, so keep reading.

When choosing Polymarket traders to copy, avoid treating a rank as a recommendation. The table is designed to help you shortlist and compare wallets.

2. Find where the result came from

Open Details on a candidate. The profile's Wallet summary can flag whether gains were concentrated in one event. The Trading style tab shows market distribution and the share of positive profit associated with the largest samples. A wallet that made most of its money from one market may behave differently in the next one.

Look at Positions and History to see what the trader actually holds and has traded. Ask whether you understand those markets' rules and whether you would be comfortable seeing similar positions in your own account. If the wallet mostly trades a category you cannot interpret, that is a practical reason to keep looking.

PredScout's trader analysis helps you choose Polymarket traders to copy based on behavior rather than a headline profit figure.

3. Check the losses and the sample

On the profile, the selected period shows Period trading P&L, Total buy spend, Period P&L to buy amount, and Largest fall vs buy amount. A fall is a past decline in the measured P&L; it is not the maximum loss that a future follower could face.

Review the P&L chart across more than one window. A smooth-looking line can come from limited history or a particular market type. Check the trade count and the number of complete weeks available before deciding that the pattern is stable. If a measure shows a dash or lacks enough data, treat it as unknown rather than favorable.

The Copy Grade is a separate historical summary. Its grade uses a fixed 30-day rating window, so switching the profile's display period does not change it. Open the grade explanation to see the dimensions it considers; do not use the letter alone to choose a trader.

4. Ask whether you can copy the trade sizes

In Trading style, check median buy size and trading frequency. A trader placing many tiny orders can be hard to follow with a smaller account, because your scaled order may fall below a market's minimum. A wallet making large, infrequent trades creates a different risk: one copied position could consume too much of your planned capital.

Use the profile's Copy Strategy Calculator to enter a hypothetical capital amount and copy ratio. For example, a 5% ratio turns a $1,000 target buy into a $50 intended copy before market constraints. The calculator shows estimated coverage from recent history. It does not replay fills, and it excludes slippage and fees.

Your own available funds, per-trade cap, market liquidity, and approval settings can change what actually gets copied. This is why a profitable wallet may be a poor match for your setup.

5. Make a short comparison sheet

For two or three candidates, write down the same facts: selected period, recent activity, typical buy size, number of trades, main market categories, largest historical decline, and estimated coverage at your proposed ratio. Add one sentence about what you still do not understand.

This simple Polymarket trader analysis makes it easier to notice a mismatch. If one wallet trades markets you understand and has sizes your Paper strategy can handle, test it before considering Live mode. Paper results remain simulated and can differ from live execution.

You have enough information to choose Polymarket traders to copy when you can explain the wallet's behavior and your planned limits without relying on its rank or grade.
