Answers: "What is this Polymarket trader betting on? Are they profitable?"

Finding an active trader address: Source from trades-by-market (guarantees trade history) rather than top-holders (position holders may have no recorded trades):

# Step 1: find active traders from a market
nansen research pm trades-by-market --market-id <market_id> --limit 5
# → seller/buyer addresses with confirmed trade history — use one as ADDR below

ADDR=<polymarket_address>

nansen research pm trades-by-address --address $ADDR --limit 20
# → timestamp, market_question, event_title, taker_action, side, size, price, usdc_value

nansen research pm pnl-by-address --address $ADDR --limit 20
# → question, event_title, side_held, net_buy_cost_usd, unrealized_value_usd, total_pnl_usd, market_resolved

Note: addresses sourced from top-holders may return empty trade history — use trades-by-market to find addresses with confirmed activity.

Look at PnL across resolved vs unresolved markets to gauge trader skill. Large positions in trending categories signal conviction.
