In backtest, only 2% of 0xa53b…4021's buys could be fully copied at a 5-minute delay

Economy 0xa53ba9d683f68602ccd767512d5c862a43824021 Profile on Polymarket

Only 2% of this trader's buys could be fully copied at a 5-minute delay, and another 11% only partly; the +$2,636 comes from the part you could copy. A copier who mirrored 0xa53b…4021's 761 buys across 221 markets with a 5-minute delay and $100 per trade would have kept 52% of the leader's returns: +$2,636 against +$5,023 for the leader at the same size. In this backtest, most of the edge survived the delay, and 2% of buys could be filled within 10 minutes. The remaining gap is delay cost $1,973, slippage $176.51 and fees $237.62. In the backtest, this simulated copy would have tied up to $804.38 at once across 100 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. 265 estimated: 68 high · 95 medium · 102 low · 447 thin How we estimate

  5. Follower PnL+$2,636

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.
