Crypto 0x4cdb2582b32604b89b1fbd71b58898de48a3172c Profile on Polymarket

Only 13% of this trader's buys could be fully copied at a 5-minute delay, and another 9% only partly; the −$948.63 comes from the part you could copy. A copier who mirrored 0x4cdb…172c's 1,385 buys across 390 markets with a 5-minute delay and $100 per trade would have ended at −$948.63. The leader lost $383.46 at the same size, so there were no returns to keep: delay cost $440.48, slippage $4.89 and fees $119.80. In the backtest, this simulated copy would have tied up to $3,963 at once across 292 positions.

Copy delay

Each time the trader buys, the simulation copies this much. Not a total budget.

The headline numbers only count what real trades in the 10 minutes after the delay prove. “Including estimates” also counts the unproven part of a buy when order-book or trading-volume evidence says it was fillable, at an estimated price. Treat it as an upper view, not a promise. 840 estimated: 175 high · 378 medium · 287 low · 356 thin How we estimate

  5. Follower PnL−$948.63

Leader PnL is scaled to your per-trade size. Delay cost is the price move between the leader's fill and yours; slippage is walking the book to fill your size; fees use the 2026 fee schedule. Methodology.

Trades

Each leader buy and the copy we simulated at the selected delay. Open “Details” to see the market fills behind the copy price.

How fills are simulated: a copy can only fill against real taker buys of the same outcome within 10 minutes after the delay, so the headline numbers are conservative. Fill basis adds a second opinion: where no trade proved a fill, order-book or volume evidence may say the size was still fillable (an estimate, never in the headline). Methodology.
