Finance 0xf9e1aa52914cbc4e88274a04adea7f53248f0458 Profile on Polymarket

Provisional4 buys are too recent to evaluate at this delay: the market data after them isn't indexed yet, so they're left out of these numbers. Computed Oct 26, 2026, 02:03 UTC.

Only 14% of this trader's buys could be fully copied at a 5-minute delay, and another 25% only partly; the +$17,230 comes from the part you could copy. A copier who mirrored 0xf9e1…0458's 1,818 buys across 52 markets with a 5-minute delay and $100 per trade would have made +$17,230 — more than the leader's +$4,489 at the same size, so the copier kept all of the leader's returns and more (383.8%). That happens when prices keep moving the leader's way after they buy and a later entry ends up cheaper: the delay helped by +$15,611, slippage $2,063 and fees $808.19. A small sample can flip this, so compare the other delays and the trades below. In the backtest, this simulated copy would have tied up to $2,549 at once across 713 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. 914 estimated: 552 high · 153 medium · 209 low · 539 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.
