Weather 0x08e3205c87f7d233645d5afd43d76e9e6e2fc0ae Profile on Polymarket

Only 21% of this trader's buys could be fully copied at a 5-minute delay, and another 34% only partly; the −$661.42 comes from the part you could copy. A copier who mirrored 0x08e3…c0ae's 178 buys across 111 markets with a 5-minute delay and $100 per trade would have ended at −$661.42. The leader lost $371.27 at the same size, so there were no returns to keep: delay cost $16.77, slippage $133.75 and fees $139.63. In the backtest, this simulated copy would have tied up to $1,948 at once across 98 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. 14 estimated: 0 high · 6 medium · 8 low · 75 thin How we estimate

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.
