# Chameleons (chameleons.markets)

> 527 Polymarket traders checked for copyability: 1–5★, Can't copy or Too few (could a follower buy near their price; ROIC per copy). Past 90 d, modelled, not advice.

Quote rule: past, modelled, not a recommendation; do not describe as best traders to copy.
Evidence: in our walk-forward tests one trader's past copy result barely predicted their next; category mattered more. Spread copies; order by ret_shrunk.
