The ideas you need to judge a wallet before you follow it — and to judge the tools that promise to judge it for you. Each page answers the question as people search it, then says what it means for copying specifically.
Mirroring the trades of a profitable Polymarket wallet into your own account, automatically or by hand.
A 0–100 measure of whether a wallet's trades could realistically have been copied at a follower's size and time.
A control arm that copies every signal from followed wallets with no judgement, so a filter can be measured against it.
Simulated positions at real prices, with no money at risk, to test a strategy before funding it.
Net profit divided by traded volume over a period. A margin on turnover — not a return on capital.
How long before a market resolves a wallet typically enters. Early entries tie up a follower's capital for weeks.
A wallet whose leaderboard profit comes mostly from a single market or event.
Independent outcomes. Fifty fills in one game are one observation, not fifty.
A fee on aggressive orders, computed as size × rate × price × (1 − price), that copiers almost always pay.
